| 摘 要： | 考虑荷载的循环特性,研究了循环荷载作用下双层饱和地基在半透水边界条件下的一维固结问题.根据瞬时加载条件下的解,通过积分的方法,得到了循环荷载下的一维固结解析解.根据解析解编制了相应的计算程序,计算分析表明:上下半透水边界的透水性减弱,超静孔压的消散显著减慢;超静孔压随循环荷载也呈周期性变化.

| Abstract: | Considering the cyclic characteristic of load,the problem of one dimensional consolidation for a double-layered ground with impeded boundaries under cyclic loadings is studied.According to the solution in the condition of constant loading,the analytical solution of cyclic loading is developed by the method of integral.Based on the solution,a program is developed.It has been showed that a decrease in permeability of sand mat and subjacent bed will decrease the speed of dissipation of the pore water pressure significantly,and that the pore water pressure varies cyclically with cyclic loading. |
