摘要
回填层采用振冲密实,下卧淤泥质软粘性土采用排水固结法,排水通道可以是砂桩或塑料排水板等,利用回填层荷载进行预压。实践证明,选用合适的施工参数,采用不加填料的振冲密实,水上砂桩、塑料排水板施工加强各工序的质量控制,可以满足设计要求,取得较好的效果。
Applying vibro-compaction for backfill layer and drain consolidation for very soft clayey soil below,using sand pile and plastic drain as drainage,the weight of backfill layer as preloading.Testifing by practice,can gain good results and meet design requirements through no-fill vibro-compaction by choosing suitable parameters and controlling construction quality of sand pile and plastic-board.
