摘要
本文以珠江三角洲地区某电厂地基处理项目为例,分析采用真空-堆载联合预压法加固软土地基时真空度、孔隙水压力、地面沉降及水平位移的变化规律,并结合现场检测结果,分析和评价真空-堆载联合预压法的处理效果。结果表明:真空-堆载联合预压法加固软土地基能够有效提高软土层的物理力学指标,加固效果良好。本文研究成果可为类似工程提供借鉴。
Taking as background the foundation treatment project of a power plant in the Pearl River Delta,the variation rules of vacuum degree,pore water pressure,land subsidence and horizontal displacement when consolidating mollisol foundation with vacuum and preloading method are analyzed,while the treatment effect of vacuum and preloading method is analyzed and evaluated by combining field test results.The results show that the vacuum and preloading method for consolidating mollisol foundation can effectively improve the physical and mechanical index of mollisol layer with a great reinforcement effect,and it can provide references for similar projects.
