输电铁塔桩-板复合基础上拔承载力特性试验及理论分析

沿江和沿海地区的地质条件多以软弱地基为主,其地基承载力相对较低,不利于输电线路基础设计、施工和运营安全。设计并制作了单板基础、单桩基础和桩-板复合基础的上拔承载力的试验模型,开展三类基础的上拔承载力试验,研究三类试验基础的上拔承载力特性和失效模式。试验结果表明,与单板基础和单桩基础相比,桩-板复合基础的上拔荷载-位移曲线呈缓慢上升形式,桩-板复合基础具有较高的承载力和抵抗变形能力,其受力特性接近于单桩基础。此外,由复合基础的模拟分析可知,上拔加载后期板和桩的承载比例约各50%,桩和板具有较好的协同受力性能。结合现有复合桩基的相关理论,提出了基于单桩抗拔承载力的桩-板复合基础设计方法,为输电线路的复合基础设计提供参考。     

传统建筑材料在当代环境艺术设计中的运用与研究

在经济不断发展的大背景下,人们的审美意识也不断增强,对于建筑材料与环境艺术的融合提出了更高的要求,并在现在的环境艺术设计中加入了更多新鲜有趣的理念。然而由于固有理念的束缚和一味求新、求变思想的出现,对于传统建筑材料的使用却遇到了不足。其实,在当代环境艺术设计中,环境设计的基本元素,不仅要能表现艺术,在视角和造景效果上也要能体现出很大的美学价值。本文结合当前传统建材料的应用情况,对其与当代环境艺术设计的结合做一个简单的阐述,对实际设计的美学造诣深入探究,让有价值的传统建筑材料绽放光彩。     

Rethinking organizational design for managing multiple projects

This paper aims at positioning organizational design as an important phenomenon in the field of project management with a high potential of contributing to organizational theory. While organizational design has been neglected by scholars of management and organizational theory, it has been of great interest to those from the project management field. This incongruence—comprising the focus of this study—calls for new insights on theorization in context. The paper provides a preliminary theoretical framework combining contingency theory, the historical approach and social theory to understand organizational design, both as a thing and as a process. It provides empirical evidence from three case studies in healthcare. Findings confirm the specificity of each design while at the same time adopting a similar temporal pattern. We take this opportunity to highlight the seminal work of Rodney Turner on project-based organization and design.

Does the tender,auction and listing system in land promote higher housing prices in China?

Using monthly data on national housing prices from July 1998 to June 2015, we investigate the effect of the ‘Tender, Auction and Listing’ (hereafter TAL) system on housing prices in land, implemented on 31 August 2004. We apply the additional polynomial regression discontinuity method which effectively eliminates the effects of several confounding factors such as financial crisis, ‘New National Ten Provisions’ and ‘9.30 New Regime’. We find that, although the TAL has caused the national average housing prices to go up by 10%, accounting for 11% of total increase in housing prices in the last year, it does not constitute the major driver for housing prices. Furthermore, our results indicate that TAL has exerted a larger impact on commercial and residential properties, especially in the middle and west regions. By examining the transmission mechanisms, we find that the effects of TAL are mainly via government’s starvation-style land supply effect and market-reshuffling effect.

节能在建筑设计中的应用

随着国民经济的快速发展,我国的能源消耗迅速,能源的缺乏为我们的经济发展敲响了警钟。作为能源消耗的大户--建筑业,节能必须要提上日程。加强节能在建筑设计中的应用,降低能源的消耗,成为了建筑设计的重点。     

论建筑设计中建筑文脉沿存

建筑设计中的文脉关注的是个体建筑与建筑群之间的关系,重视新老建筑在心理、视觉和环境上的沿存性和连续性。建筑物的设计的意义以及所具有的功能需要通过空间和时间上的文脉来实现,同时也起到了对文脉的协调作用。     

城市养老院建筑的人性化设计

老年人是一群比较特殊的群体,城市疗养院要想为老年人提供更好的生活,在建筑设计方面应该尽可能地为老人提供方便,对老人衰退的感觉机能和生理机能加以综合考虑,从而实现最为人性化的设计,为老年群体的起居生活提供便利。
