堆载联合排水板处理渣土回填地基分析

以深圳市某软土地基处理为依托，对堆载联合排水板处理渣土回填软土地基过程中，不同渣土厚度、排水板间距、排水板深度、堆载值、堆载速率进行数值模拟。分析了不同因素对沉降及侧向位移的影响；采用设置应力释放沟和打设隔离桩的措施，减小对周边围堰及道路的影响。

Analysis of Residue Soil Backfill Foundation Treated by Heaped Loading with Drainage Board

Relying on the treatment of a soft foundation in Shenzhen City, as for the treatment of residue soil backfill soft foundation by heaped loading with drainage board, numerical simulation of different residue soil thickness, drainage board spacing and depth, heaped loading value and rate were carried out; and then the effects of the factors on the settlement and the lateral displacement were analyzed. Stress release channel and shelter piles were set up to reduce the impact on the surrounding dam and road.
