摘要
结合某深基坑工程实践,通过原位测试和室内土工试验,得到基坑设计参数,经过计算后确定基坑支护设计方案,并对基坑工程的施工和监测要点进行了分析,可为以后的工程设计提供参考。
This paper presents a case study of the supporting design for a deep excavation. The geotechnical design parameters are obtained through a thorough investigation of the site topographical, geotechnical and hydrological conditions in combination with in-situ and laboratory test results. The final supporting system selected was the rotary drilled and cast-in-place soldier piles plus three layers of reinforced concrete beam supports. The jet grout was utilized to seal off groundwater among soldier piles. The paper also briefly introduces the deep excavation construction and the site monitoring program.
