通过对青海察尔汗盐湖地区的饱和盐渍土天然地层强夯和碎石排水桩加强夯进行孔隙水压力测试,重点探讨了碎石排水桩加强夯处理盐渍土地基孔隙水压力变化特性、强夯时孔隙水压力峰值与土层表面接触应力峰值的关系、不同夯击遍数下的孔隙水压力、排水桩的作用以及强夯夯击间歇时间等问题,对碎石排水桩加强夯处理饱和盐渍土地基技术的研究与工程实践有一定的指导意义。
Through the test of pore water pressure on the dynamic compaction of natural saline saturated soil and gravel drainage pile in Qinghai Chaer Khan Salt Lake, the pore-water pressure change characteristics of gravel pile drainage pillars strengthened by ram treatment of saline soil foundation are discussed emphatically. The relationship between the peak pressure of pore water and the surface contact stress peak during dynamic compaction, the pore water pressure under different compaction times, the function of drainage piles and intermittent time of dynamic compaction, Saturated saline soil foundation technology research and engineering practice has some guiding significance.
