超孔隙水压力监测在大夯击能强夯中的成果分析

Analyses of Excessive Pore Water Pressure in High Energy Dynamic Compaction

分析强夯最佳夯击能以及强夯间歇时间的确定方法,并讨论超孔隙水压力在大夯击能强夯中的变化情况。工程应用结果表明,强夯工程影响深度约为11.0m,强夯有效加固深度为9.0m。

Through a case study, the dissipation of excessive pore water pressure during the high energy dynamic compaction process is evaluated. The dynamic compaction energy and the time interval between two compaction passes is optimized with respect to maximizing the soil improvement achieved. In this case study, the influence depth of the high energy dynamic compac- tion is determined to be approximately 11 meters and the effective improvement depth is determined to be 9 meters.
