发布时间：2018-12-07 11:52
【摘要】：近几十年来，随着城市化进程的加快以及人口数量猛增，城市用地紧张等因素促使高层建筑以及超高层建筑发展迅速，地下工程也成为土建结构工程中的重中之重。地下工程的施工安全离不开基坑工程的支护，大多数深基坑工程都是在城市中开挖，城市中各方面条件都比较复杂，基坑支护设计不当必然会引起不必要的工程事故，并且事故一般较大，不但易造成人员死亡，同时也会给工程本身造成巨大的经济损失，这也就对基坑支护工程提出了较高的要求。 论文总结了基坑支护工程的国内外研究现状及发展趋势，论述了基坑支护工程的相关基本理论，包括支护结构常见类型、土压力理论、几种支护结构设计计算及其稳定性验算。以扬中市口岸查验综合大楼为依托经全面分析和综合比较，确定了该工程的基坑支护方案，验算了该基坑支护结构的整体稳定性，阐述了开挖、降水等施工工艺。并对支护方案涉及到的参数进行了详细论证，，总结了项目的施工组织设计。结果表明该工程基坑支护的施工方案符合相应规范、标准，具有良好的经济效益。
[Abstract]:In recent decades, with the acceleration of urbanization and the rapid increase of population, the shortage of urban land and other factors promote the rapid development of high-rise buildings and super-high-rise buildings, and underground engineering has become the most important part of civil engineering. The construction safety of underground engineering can not be separated from the support of foundation pit engineering. Most deep foundation pit projects are excavated in cities, and all aspects of the conditions in the city are quite complex. The improper design of foundation pit support will inevitably cause unnecessary engineering accidents. And the accidents are usually larger, which not only easily cause death, but also cause huge economic losses to the project itself, which puts forward higher requirements for foundation pit support engineering. This paper summarizes the research status and development trend of foundation pit support engineering at home and abroad, and discusses the relevant basic theories of foundation pit support engineering, including common types of supporting structure, earth pressure theory, design calculation and stability checking calculation of several kinds of supporting structures. Based on the comprehensive analysis and comprehensive comparison of Yangzhong Port Inspection complex Building, this paper determines the foundation pit support scheme of the project, checks and calculates the overall stability of the foundation pit support structure, and expounds the construction techniques such as excavation and dewatering. The parameters involved in the support scheme are demonstrated in detail, and the construction organization design of the project is summarized. The results show that the construction scheme of foundation pit support of this project accords with the corresponding standard and standard, and has good economic benefit.
