浅谈道路与桥梁工程施工的质量控制策略

作为推动国家建设的重要基础保障,市政道路桥梁工程可以更好地发挥其提高交通运行效率的作用,从而实现国家基础设施建设的优化。目前市政道路桥梁由于施工流程和工序比较复杂,因而在施工过程中会受到多种施工因素的影响,进而导致一系列质量问题的出现,因此本文将对道路和桥梁工程施工中的质量控制策略进行探究,以期更好地为提升我国市政工程基础设施建设水平。     

市政道路工程路面水稳层施工质量控制

道路工程建设是基础设施建设的重要组成部分。道路水稳层整体质量直接影响交通的稳定性与安全性,而水稳层施工技术的不足会直接威胁到人们的出行安全和出行效率。传统的道路水稳层施工主要在出现质量问题之后采取相应的修复措施进行修复,但修复时间长且成本高。为此,落实和加强对道路水稳层施工质量控制的分析,不仅可以有效降低后期养护维修的成本,而且能提高道路工程施工整体质量,维持其运营效果,保证人们日常的出行安全。路面水稳层作为市政道路工程的重要组成部分,直接影响市政道路体系的结构稳定性及使用寿命。基于此,文章对市政道路路面水稳层施工工艺进行研究,分析影响路面水稳层施工质量的因素,并提出相应的质量控制措施,为提高我国市政道路工程质量,推动交通事业发展做出贡献。     

软基加固施工技术在市政道路施工中的应用

随着我国近些年社会发展水平的不断提高,对于道路行业也取得了很大的进步。在道路工程施工过程中施工质量和施工的效率成为整个行业关注的重点,由于道路工程施工的特殊性,在施工的现场会遇到不同的地质和气候环境,其承载能力也会不同。因此,要结合具体的施工情况,选择针对性的施工技术方案,确保整个工程的施工效果。道路工程施工过程中软基基础施工是整个工程施工中的重要项目,针对于软基项目的特点要采取针对性的处理方法,这样才能够提高整个工程的整体建设水平。由于我国各地区的地理环境与土壤环境各不相同,部分地区在进行市政道路施工过程中经常会遇到目标土层的压缩量较高、土层中含有较多的有机物质的现象,因此需要相关项目方做好软土地基地处理,以降低软土地基对市政道路带来的影响。以市政道路施工项目为研究对象,探讨在市政道路施工过程中软土加固技术的应用路径。     

市政道路工程沥青路面接缝施工技术研究

市政道路工程作为城市的基础建设项目受到全面高度关注,尤其在经济不断发展的前提下,市政道路建设项目数量逐渐增多。但是,在市政道路沥青路面接缝施工中存在着一些问题,而这些问题会影响到接缝技术的效果,即使在良好的技术操作出现的问题也无法避免,在一定程度上会影响市政道路工程的建设与发展。所以,在市政道路沥青路面接缝施工中,需要结合当前的施工问题进行分析,加大对施工的关注,落实科学的技术操作,并且保障所有操作的规范化和合理化,满足接缝施工技术的应用要求,为市政道路建设与发展提供支持。     

浅谈公路工程高填方路基施工技术

高填方路基施工技术对于整个道路工程的施工质量会有决定性的影响,在实际施工时,必须要配备专业人员全程进行监管,以保证最终的施工质量。在诸多施工案例中,高填方路基施工过程中存在着诸多缺陷,这种质量缺陷会对道路的稳定性以及路基的强度造成巨大的影响,道路的整体质量也无法得到保证,道路的使用寿命会大幅度缩短。为了提高市政道路的整体质量,保证使用寿命,必须要对高填方路基施工技术进行优化。     

市政道路建设中沥青道路施工和养护研究

当前我国处于社会与经济快速发展进程中,各地区政府对市政工程建设质量非常重视,其中关注度最高的是市政道路沥青混凝土路面施工。因为城市发展最重要的就是道路,若是道路出现问题不仅会影响群众出行,还会对地区经济发展带来阻碍,所以在发展过程中就需要结合实际情况去制定相应工作计划。为此各地区在发展过程中开始对市政道路沥青混凝土路面施工技术进行总结分析,以通过这样的方式来优化施工方案,进而提高工程质量与使用寿命。

城市道路监控工程规划与设备施工（下）

城市道路监控是兼顾城市安全与道路交通监控两用的方案，是现代城市不可缺少的市政建设项目，城市道路监控工程可以加强道路功能和优化道路使用。在规划和设计时进行城市道路监控工程设计，是保障城市安全规划实施和道路通畅的重要环节，而目前还有很多城市都没有做此项工作。本文是结合已建置城市的成功经验情况，阐述道路监控的必要性，包括系统内容、规划原则及施工安装细节的工程说明。     

道路桥梁工程的常见病害与施工处理技术

近年来,我国的各项建设都在不断发展,城市道路的建设也取得了飞速的发展,从而更好地促进我国经济的增长。但是,一些大型的道路桥梁工程在设计施工过程中,经常会出现诸多的安全隐患,严重影响到道路桥梁工程的施工质量,使其在使用阶段出现质量问题,威胁人们的生命安全。为此,道路桥梁工程的施工人员必须通过适当的处理手段对常见的问题和病害进行防治,改善相应的施工处理技术,以便大幅度提升道路桥梁工程的安全性,为我国经济的持续发展提供强大的动力。

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.     

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.     

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008

Explanation and prediction: an architecture for default and abductive reasoning

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.     

Three Process Perspectives: Organizations, Teams, and People

This paper provides the author's personal views and perspectives on software process improvement. Starting with his first work on technology assessment in IBM over 20 years ago, Watts Humphrey describes the process improvement work he has been directly involved in. This includes the development of the early process assessment methods, the original design of the CMM, and the introduction of the Personal Software Process (PSP)^SM and Team Software Process (TSP){^SM}. In addition to describing the original motivation for this work, the author also reviews many of the problems he and his associates encountered and why they solved them the way they did. He also comments on the outstanding issues and likely directions for future work. Finally, this work has built on the experiences and contributions of many people. Mr. Humphrey only describes work that he was personally involved in and he names many of the key contributors. However, so many people have been involved in this work that a full list of the important participants would be impractical.     

基于复小波噪声方差显著修正的SAR图像去噪

提出了一种基于复小波域统计建模与噪声方差估计显著性修正相结合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像斑点噪声滤波方法。该方法首先通过对数变换将乘性噪声模型转化为加性噪声模型,然后对变换后的图像进行双树复小波变换(Dualtree Complex Wavelet Transform,DCWT),并对复数小波系数的统计分布进行建模。在此先验分布的基础上,通过运用贝叶斯估计方法从含噪系数中恢复原始系数,达到滤除噪声的目的。实验结果表明该方法在去除噪声的同时保留了图像的细节信息,取得了很好的降噪效果。
