高速公路软基砂井预压法处理效果分析

Study of Improvement Effects by Sand Drain Preloading for the Expressway Soft Subsoil

探讨了砂井预压法在高速公路软基处理中的处理效果。分析了砂井处理前后路堤软基强度和稳定性的改善情况,以及在不同场地地质和荷载条件下砂井预压对于加快地基早期固结沉降和减少工后沉降的作用。

Based on the improvement effects of soft foundation for expressway with the sand drain preloading the variances of strength and stability for the soft subsoil before and after the improvement are presented, the quickening effect of subsoil consolidation of the reducing effect of foundation settlement for different condition of geological profile and loading by preloading with sand drain are discussed also.
