深基坑支护工程是岩土工程施工中关键技术内容,其施工质量对岩土整体的安全性和稳定性影响比较大。深基坑工程是对地面下土体的施工技术。岩土工程基坑支护技术有土钉墙支护方案、灌注桩支护方案、护坡桩支护方案以及地下连续墙支护方案。文章通过某市岩土工程施工案例,讨论了深基坑支护技术的应用情况,从作业区域类型分析、地震烈度确定、作业区域土质构造以及支护方案选择方面给出了技术应用分析。
Deep foundation pit support engineering is the key technical content in geotechnical engineering construction, whose construction quality has great influence on the overall safety and stability of rock and soil. Deep Foundation Pit Engineering is the construction of soil under the ground. The geotechnical engineering foundation pit support technology includes soil nailing wall support scheme, bored pile support scheme, slope protection pile support scheme and underground diaphragm wall support scheme. This paper discusses the application of the deep foundation pit supporting technology through the case of geotechnical engineering in a certain city. The technical application analysis is given based on the analysis of the type of work area, the determination of earthquake intensity, the soil structure of the work area and the selection of support schemes.
