The soil behavior in initial loading, unloading and reloading stages can be reflected by adopting different model parameters.
土体在初始加载与卸载和重新加载阶段性质的差别通过采用不同的模型参数加以反映。
In addition, foundation base may be in dangerous conditions such as sand pipings and upheaval deformations because of unloading soil above artesian aquifer.
另外，当遇到承压含水层时，由于上部土体的卸荷，坑底有被顶破而发生涌砂、隆起的危险。
In the calculation of soil heave, the deformation modulus is obtained by taking the unloading path as the basic stress path and the effect of dewatering is not taken into account.
目前对于深基坑的回弹量计算，都是以基坑开挖卸荷为基本应力路径获取变形模量，并未考虑降水的影响。
