北京市中心区CFG桩复合地基场地区划

Site Division for the Composite Foundation with CFG Piles in Central Area of Beijing

本文通过对北京平原第四纪沉积规律的分析,结合北京市中心地区多项岩土工程勘察资料,概化了北京市中心区地基土的11个层次。同时,综合北京市中心区的岩土工程地质、水文地质、地面沉降以及断裂构造等因素将中心区CFG桩复合地基场地做了区划。这一成果为本区的工程勘察、地基处理的设计施工提供了参考依据。

Through the analysis on the features of Quaternary sedimentation in Beijing plain, the 11 levels for the foundation soils in the central area of Beijing are generalized based on the data from several geotechnical investigations. The site division for the composite foundation with CFG piles in the central area is presented after considering the factors such as geotechnical engineering geology, hydrological geology, ground settlement and fault structure, which provides the basis for the engineering investigations, the design and construction of soil treatment in the area.
