| 摘 要： | 提出了一个改进的土结构性弹塑性损伤模型。该模型引入修正剑桥模型的屈服函数来描述损伤土特性，并建议了新的损伤演化规律。由于剑桥模型本身建立在大量重塑土试验的基础上，故能较精确地描述完全损伤土的特性；此外，其参数有较为完善的测定方法，且积累了丰富的经验值。该改进的模型能较好地应用于工程实践，并易于推广。

| Abstract: | An updated elastoplastic model is presented. The model turns to the updated Cam clay model’s yield function to describe the characteristics of damaged soft-clay and suggests a new varied law of the damaged variable. Owing to Cam model based on the remolded samples test, the remolded soil characteristics can be exactly described. The Cam parameters possess a comparatively perfect detecting methods and accumulate various empirical values. The updated elastoplastic model can be easily popularized and applied to engineering. |
