| 摘 要： | 根据双标量各向同性弹性损伤理论,提出了一个土体损伤模型,给出了相应的损伤演化方程。将其运用到地基土的静载荷试验中,采用修正分层总和法得到了地基土的理论荷载-沉降曲线,与实测曲线进行比较,验证了本模型的正确性。

| Abstract: | Based on double scalar isotropic damage theory,a new soil damage model and damage evolution equations were presented.The new model was used to determine the load-settlement of foundation by means of the modified layer-summation.A comparison of theoretical and field results showed reasonable agreement and confirmed the validity of the proposed theory. |
