【摘要】：近幾十年來，隨著城市化進程的加快以及人口數(shù)量猛增，城市用地緊張等因素促使高層建筑以及超高層建筑發(fā)展迅速，地下工程也成為土建結(jié)構(gòu)工程中的重中之重。地下工程的施工安全離不開基坑工程的支護，大多數(shù)深基坑工程都是在城市中開挖，城市中各方面條件都比較復雜，基坑支護設(shè)計不當必然會引起不必要的工程事故，并且事故一般較大，不但易造成人員死亡，同時也會給工程本身造成巨大的經(jīng)濟損失，這也就對基坑支護工程提出了較高的要求。 論文總結(jié)了基坑支護工程的國內(nèi)外研究現(xiàn)狀及發(fā)展趨勢，論述了基坑支護工程的相關(guān)基本理論，包括支護結(jié)構(gòu)常見類型、土壓力理論、幾種支護結(jié)構(gòu)設(shè)計計算及其穩(wěn)定性驗算。以揚中市口岸查驗綜合大樓為依托經(jīng)全面分析和綜合比較，確定了該工程的基坑支護方案，驗算了該基坑支護結(jié)構(gòu)的整體穩(wěn)定性，闡述了開挖、降水等施工工藝。并對支護方案涉及到的參數(shù)進行了詳細論證，，總結(jié)了項目的施工組織設(shè)計。結(jié)果表明該工程基坑支護的施工方案符合相應規(guī)范、標準，具有良好的經(jīng)濟效益。
[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.
