强夯置换处理不良地质路基加固效果研究

An Effect Study of Dynamic Compaction Replacement for Poor Geological Roadbed

结合实际工程地质特点,采用强夯置换对不良地质路基进行加固,处理前后载荷试验结果表明:强夯置换处理此类建筑垃圾填埋场能够起到良好的加固效果,路基土体承载力能提高2倍左右;施工过程孔隙水压力与水平位移监测数据表明,强夯置换置换体对路基土体的挤密作用是土体承载力提高的主要原因。

Based on the practical engineering geological characteristics,the roadbed with poor geological condition is reinforced by the dynamic compaction replacement. The comparative load test results of before and after the process- ing show that the dynamic compaction replacement brings a good reinforcement effect for building landfills, the roadbed bearing capacity of soil increases 2 times; the monitoring data of pore water pressure during construction and horizontal displacement show that the increase of soil bearing capacity is due to the compaction of the dynamic consolidation replacement body on roadbed soil.
