摘要
结合饱和软土地层强夯现场测试结果,分析了不同强夯能量施工条件下地层内部沿深度方向的分层沉降随单点强夯次数和遍数的变化过程,给出了距离强夯中心点不同水平距离处的侧向位移沿深度方向随强夯次数增加的变化过程。利用这些结果,进一步分析强夯冲击荷载作用对饱和土地基的扰动影响。同时,论文还对软土地层中强夯法的加固机理、强夯能量的合理使用以及加固效果进行了分析。
Using various magnitudes of dynamic energy in field tests of saturated soft ground,this paper analyzed the changes of settlement of various layers with increasing the numbers of drops and the numbers of passes.Furthermore,the horizontal displacements along depth in various distances from the dynamic point are compared.Using these test results,the disturbance effects on saturated soft soil layers due to dynamic loading are discussed.Besides,the improvement mechanism and the choices of dynamic energy are analyzed.
