摘要
结合某填海造地道路地基处理工程实例,探讨塑料排水板堆载预压法的加固机理;基于现场软基沉降监测实测数据,采用双曲线法对加固后的软土地基沉降进行预测,并分析地基的最终沉降量及固结度。研究结果表明:塑料排水板堆载预压法在软基处理中的加固效果较好,堆载预压结束后,软基固结度可达到80%～95%,满足设计要求。
Combined with a road foundation treatment engineering example for land reclamation, the reinforce- ment mechanism of preloading accumulating load method with plastic drainage plate was discussed. Based on the measured data of soft foundation settlement monitoring, the hyperboric method was used to predict the settlement of reinforcing sofe soil foundation, and the final settlement and consolidation degree of the foundation were stud- ied. The results show that consolidation effect of reinforcing soft soil foundation by preloading accumulating load method with plastic drainage plate is good and the soft foundation consolidation degree can reach 80% -95% after preloading which can meet the requirements of design.
