摘要
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。
It researches stress and void water pressure of saturated soft clay soil due to load of train, and obtains control differential equation applying for Laplace transition, opposite force of foundation surface and bank as boundary condition of surface load of foundation, which calculated under action by elastic foundation Timoshenko beam and moving load, then obtains semi-analytic solution of saturated soft clay soil.
