[提要] 實測沉降值與按地基規(guī)范GB50007-2002計算所得值之間存在很大的差異。在研究了滬、浙、閩各地實測沉降數(shù)據(jù)的基礎(chǔ)上，依據(jù)關(guān)于壓縮模量正比于有效應(yīng)力等的理論分析，在深層土的壓縮模量中考慮了土的自重壓力并進行調(diào)整，計算后取得了與實際工程沉降較相符的結(jié)果。
[關(guān)鍵詞] 深層 軟土 附加壓力 壓縮模量 沉降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.
Keywords: superirnposed stress; soil compression modulus; settlement
