水下灌浆隧道围岩应力与位移分析

目前对隧道围岩的应力与位移分析，其前提都是以围岩为均质材料，而灌浆隧道的围岩是由两层不同力学性能材料构成的夏合结构，其应力与位移特点不同于均质围岩。基于岩体的弹脆塑性模型及非关联流动法则，考虑地下水压力的作用，对灌浆隧道围岩的应力与位移进行理论分析，获得了围岩位移曲线。     

Practical method for generation expansion planning based on dynamic programming

This paper presents an efficient method which provides the optimal generation mix and the optimal generation construction process. The approximation method in which the dynamic programming technique and gradient method are combined is applied to determine the optimal generation mix with hydropower generation technologies. The successive approximations dynamic programming (SADP) technique, which is very suitable for high-dimensional multistage decision process problems, is used for obtaining the optimal generation construction process. The effectiveness and feasibility of the developed technique are demonstrated on a practical power system model which has five types of generation technologies including a hydropower generation technology.     

A bidding decision index for construction contractors

Results from applying the model on a sample of contractors, the majority of whom were international and operating in Egypt, reinforces the credibility of the developed methodology, claim the authors.     

Electronic data acquisition forms in construction management

Effective management of construction projects depends on good access to and control of data, especially data pertaining to cost and schedule control functions. However, the proper design and development of automated mechanisms have not had the facility to acquire and store quality data in a timely manner. The purpose of this paper, then, is to discuss a prototype, automated data acquisition system that was developed to support an integrated project management system. The data acquisition system is composed of an integrated set of electronic forms used in conjunction with a bar coding data-entry tool.     

Subdivision of work on construction projects

In order to control a project, construction management requires project information. This is obtained through accounting, estimating, cost management and scheduling functions which produce project reports. These reports are best obtained by subdividing the project into small parts. The ways in which each of these functions subdivides a project in order to produce its reports is discussed, together with a means of interrelating this information with a technique known as the work breakdown structure.     

长输管道建设物流管理新模式——物资配送

长输管道工程是以线路管道与沿途站场为主要内容的建设工程,其物资配送有着不同于一般物流管理的特点,点多线长,且交通不便.文章结合西南成品油管道建设工程的物资配送实践,总结出长输管道物资配送的类型,并从机构设置、计划编制、台账和报表管理等方面介绍了物资配送的管理内容及经验,实践证明,这种物资配送方法不但使业主的物资管理人员大为减少,而且使长输管道工程的物资供应更加及时有序.     

柳海矿运输大巷返修工程深部软岩支护设计研究

通过现场调查、室内试验以及理论分析,柳海矿运输大巷支护现状进行分析研究,总结破坏原因。根据现场工程地质条件、岩石特性和破坏特点,确定软岩变形力学机制为高应力膨胀性软岩,并提出采用预留刚隙柔层支护技术进行支护。     

浅谈湖滨带生态恢复建设工程施工监理的特点

指出湖滨带是连接湖泊水体和陆地的一个功能过渡界面区。它作为生物的重要栖息地,具有净化水质、缓解波浪等多种功能。因此,对湖滨带实行生态恢复建设,应予以高度的重视。笔者通过具体工程的实践,阐述了湖滨带生态恢复建设工程的特点、施工阶段的监理工作,以及对监理人员的素质要求,可供类似工程借鉴、参考。
