摘 要: 根据在珠江三角洲内收集到的近千个软土土样的试验成果,对其基本物理、力学指标进行了统计和分析,并根据实测资料和室内试验成果,分析了软土的非线性特征和蠕变特征。通过非线性弹粘性模型的计算,分析了蠕变特性对软土地基变形和孔压消散的量化影响。 Based on the test results of a large number of samples ingathered in the Pearl River Delta, the statistics and analysis about physical and mechanical indexes of soft soil are made. The characters of nonlinearity and creep of soft soil are analysed, according to the data obtained in field and laboratory tests. Through the calculation by nonlinear viscoelastic model, the quantitative influence of creep property on deformation of ground and variation of pore pressure are studied.
