摘要:以淤泥土回填土的软土地基处理为例,采用排水板强夯置换复合工艺进行加固处理。以确定施工参数和施工效果评价为目的开展单点夯试验研究。通过试验过程中过程数据采集、孔隙水压力监测、深层土体水平位移监测的结果分析施工参数,通过对处理场地进行平板静载荷试验监测和夯间土的土工试验、夯墩的重型动力触探试验等结果评价地基处理效果。试验结果证明排水板强夯置换复合工艺在软土地基加固处理中有一定的适用性。

Abstract: Taking the soft soil foundation treatment of silt soil backfill soil as an example,the composite process of drainage board and dynamic compaction replacement is used for reinforcement treatment. A single point compaction test study is carried out for the purpose of determining construction parameters and evaluation of construction effects. This paper analyzes the construction parameters based on the results of process data, pore water pressure monitoring, and horizontal displacement monitoring of deep soil during test;through the results of static load flat plate load test and geotechnical test for tamping soil,heavy dynamic penetration test on the treatment site for tamping pierce to analyze the effect of foundation treatment. It is proved that the composite process of drainage board and dynamic compaction replacement has certain applicability in the reinforcement treatment of soft soil foundation.
Keywords: foundations; soft soil foundation; drainage board; dynamic compaction replacement; monitoring; testing
