研究列车移动荷载作用下饱和软粘土中产生的应力和孔隙水压力,应用拉普拉斯变换求出在该条件下的控制微分方程,把弹性地基Ti moshenko梁及其在移动荷载作用下的动力解而计算得到地基表面与路堤之间的反力看成地基表面的荷载作为边界条件,给出移动往复荷载作用下饱和软粘土层内的半解析解。
The stress and pore water pressure in saturated soft clay under moving load of train are studied. The governing differential equation under the condition is obtained by using Laplace transform. The Ti moshenko beam with elastic foundation and its dynamic force under moving load The reaction between the foundation surface and the embankment is calculated as the boundary condition of the foundation surface, and the semi-analytical solution in the saturated soft clay layer under moving reciprocating loads is given.
