| 摘 要： | 从损伤力学的观点出发，引入损伤比因子考虑土体的损伤，根据室内试验确定了土体的损伤比及计算参数，比较了弹塑性模型，粘弹塑性模型以及考虑土体损伤的粘弹塑性模型的计算成果，结果表明，考虑了土体损伤的粘弹塑性模型计算的地基沉降与实测资料较吻合。

| Abstract: | Based on the concept of damage mechanics, a damage factor of soil is developed. The damage factor and other calculation parameters of soil are obtained through laboratory tests. A comparison of the settlements calculated by the elastoplastic model, the visco-elastoplastic model, and the visco-elastoplastic model considering damage to soil shows that the result of the last model is in good agreement with the measured data. |
