| 摘 要： | 基于Blot波动理论，研究了交通荷载作用下有限层厚软土路基-无限大弹性薄板（模拟路面）的三维振动问题，采用简谐矩形运动荷载来模拟交通荷载．通过引入势函数和Helmholtz原理，并利用Fourier变换技术，得到了矩形运动荷载作用下软土路基的应力、位移和孔隙水压力解答．利用Fourier逆变换得到数值结果，分析了不同荷载速度对地表竖向位移及路基中任意深度方向孔隙水压力分布的影响．

| Abstract: | On the basis of Biot fluctuation theory,this paper analyzes the three dimensional(3D) vibrations for limited layer thick-soft subgrade-infinite elastic thin plate(simulated pavement) under moving traffic loads,and the traffic load is simulated using harmonic rectangular moving load.By incorporating the potential function and Helmholtz principium plus Fourier transform technique,the stress of soft subgrade is obtained under rectangular moving load,and so are the solutions to displacement and pressure from fu... |
