中文摘要：
本文根据Singh和Mitchell等学者的研究结果,采用适用范围广的Singh-Mitchell蠕变速率方程描述常州地区第一弱透水层粉质粘土的蠕变特性.利用自制改装的三轴应力式流变仪,通过三轴排水蠕变试验,分析得出常州地区粉质粘土的蠕变模型形式,较不排水蠕变试验更加客观地反映了常州地区第一弱透水层长期蠕变的实际情况,从而为该区地面沉降模型中考虑粘性土体的蠕变特性提供了力学基础,并提供相应的参考数据.该模型具有参数少、适用性强的特点.
英文摘要：
Few domestic and overseas regional land subsidence models consider the present. Therefore, the corresponding simulation models seldom take account of both rheological behavior at primary and secondary consolidation. On the basis of triaxial creep tests, sih clay in the 1 aquirtard of Changzhou is analyzed and the form of Singh-Mitchell stress-strain-time relationship equation to describe the nonlinear characteristics of silt clay is given. This model has features such as fewer parameters paper provide not only the reference values for the study and good application. The conclusions obtained in area, but also the theoretical explanation for the between the deformation in the land subsidence and the variation of the water level of the aquifer.
