【摘要】：随着我国城市化进程的大力推进,地产行业大力投资开发建设,各类高耸建筑物应运而生,在向更高发展的同时地下空间开发也被受青睐,伴随着地下空间大规模的开挖,基坑支护安全稳定性就显得尤为重要。本课题围绕基坑支护稳定性这一课题,从优化基坑支护的设计方案到应用FLAC3D进行数值模拟稳定性分析,对基坑可能产生失稳的内因、外因进行探讨分析。本次研究以探讨基坑安全稳定为主线,采用宏观与微观分析相结合,现场勘察与室内分析并用,试验与模拟方法同步,多学科知识交叉综合运用,多种模式探讨分析,理论联系实践等一系列研究方法,对基坑安全稳定性进行评价。希望通过本课题的研究,给相关基坑安全稳定问题的研究分析提供参考借鉴,减少事故及安全隐患,增加经济效益,提高国民经济,促进基坑安全稳定问题研究的步伐。
[Abstract]:With the development of urbanization in our country, the real estate industry has invested heavily in the development and construction of various kinds of towering buildings, and the development of underground space has been favored along with the development of underground space, which is accompanied by the large-scale excavation of underground space. The safety and stability of foundation pit support is particularly important. This paper focuses on the stability of foundation pit support, from optimizing the design scheme of foundation pit support to using FLAC3D to analyze the stability of numerical simulation, the internal cause of the instability of foundation pit may be produced. The main line of this study is to discuss the safety and stability of foundation pit, the combination of macro and micro analysis, the combination of field investigation and indoor analysis, the synchronization of test and simulation, and the comprehensive application of multidisciplinary knowledge. The safety and stability of foundation pit are evaluated by a series of research methods, such as discussion and analysis of various modes, combination of theory and practice, etc. It is hoped that through the research of this subject, the research and analysis of the safety and stability of foundation pit will be provided with reference, reduce accidents and hidden dangers, increase economic benefits, improve the national economy, and promote the research of the safety and stability of foundation pit.
