[提要]  实测沉降值与按地基规范GB50007-2002计算所得值之间存在很大的差异。在研究了沪、浙、闽各地实测沉降数据的基础上，依据关于压缩模量正比于有效应力等的理论分析，在深层土的压缩模量中考虑了土的自重压力并进行调整，计算后取得了与实际工程沉降较相符的结果。

There is fairly big difference between the results calculated with code formula in GB50007-2002 and settlement monitoring data at building site.This paper is based on the study of building settlement monitoring results in Shang- hai, Zhejiang, Fujian area. In deep soil layer modulus calculation, some modification has been made by considering soil self weight in accordance with the theory that the soil compression modulus is in positive proportion to effective stress. The calculation results are quite close to the building monitoring data.
