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。
Combined with the field test results of dynamic compaction in saturated soft soil formation, the process of stratified settlement along the depth direction under different dynamic compaction energy conditions is analyzed with the variation process of single point dynamic compaction times and pass numbers, Lateral displacement at different horizontal distances along the depth direction with the times of dynamic compaction increasing process. Based on these results, the influence of dynamic compaction load on the disturbance of saturated soil foundation is further analyzed. At the same time, the paper also analyzes the reinforcement mechanism of dynamic compaction method in soft ground, the reasonable use of dynamic compaction and the reinforcement effect.
