摘要
大吨位堆载法静载试验对压重反力平台场地条件要求非常高,一般通过对浅层地基土进行验算和加固,采用地基处理的方法来解决反力平台下地基土承载力不足的问题,通常效果并不理想。本文提出一种在软土地区静载试验中利用反力平台试验主梁两端设置支撑桩,并结合支座下表层软弱土换填压实以支承大吨位反力平台荷载的方法,效果良好。
The large tonnage static load test has very high requirements on the site conditions of the stacked test platform. Generally,through the calculation and reinforcement of the shallow ground soil,ground treatment is adopted to solve the problem of insufficient bearing capacity of the ground soil under the pressure reaction platform,while the result is not ideal usually. In this paper,new supporting pattern of large-tonnage static load test platform in soft soil area was presented,which included two additional supporting piles under the two ends of the main girder,combined with surface soil replacement compaction,to keep the stability of stacked platform. And it has good performance.
