由河海大学农田水利系钱家欢教授等完成的“粘弹性土体固结理论及其在软基加固机理研究中的应用”获1990年度水利部科技进步理论成果二等奖。该课题系统研究了粘弹性土体固结理论及其在软基加固机理研究中的应用。采用广义Voigt 模型,导出了饱和粘弹性土体一维固结和轴对称固结的普遍解析解,论证了巴隆公式和杰普逊-乐方法中存在的问题及卡里罗定理的不适用性;提出了合理确定饱和土体粘弹性
The “Consolidation Theory of Viscoelastic Soils and Its Application in the Study of Soft Ground Reinforcement Mechanism,” completed by Professor Qian Jiahuan of the Department of Farmland Water Resources of Hohai University, was awarded the second prize of the 1990 Scientific and Technological Progress Achievement Award by the Ministry of Water Resources. This project systematically studied the consolidation theory of viscoelastic soils and its application in the study of soft foundation reinforcement mechanism. The generalized Voigt model was used to derive the general analytical solution of one-dimensional consolidation and axisymmetric consolidation of saturated viscoelastic soils. The problems in Baron’s formula and Jeppesen-Lee method and the inapplicability of Carrillo’s theorem were demonstrated. Sex; proposed to reasonably determine the viscoelasticity of saturated soils
