| 中文摘要: |
| 基于真空—堆载联合法在珠海横琴能源站软土地基处理方案的实施,对现场真空度、孔隙水压力、深层水平位移、地表沉降、地下水位、分层沉降监测资料进行分析,以及地基处理前后的室内试验和现场原位试验资料进行对比和研究,结果表明:真空—堆载预压后,软土地基的沉降速率指标、固结度、承载力均达到设计要求,软土各项物理力学指标明显改良,预压效果良好；为具有相同或类似条件地域的软土地基加固处理提供了经验. |
| 英文摘要: |
| Based on the implementation of the vacuum-surcharge preloading method in Zhuhai Hengqin power station,the in-situ monitoring data of vacuum degree,pore water pressure,deep horizontal displacement,ground settlement,ground water levels,settlement at different depth was analyzed,and the data of the lab and in-situ test before and after soft foundation treatment was studied and contrasted in this paper.It showed after vacuum-surcharge preloading,the settlement rate criterion,consolidation degree,the bearing loading capacity of the foundation reaches design requirements,all physical-mechanical of the soft soil is improved obviously and the experiences are provided for the ground treatment of soft soil of the same type or similar conditions. |
