摘要
以广州中船龙穴造船基地某项目为例,详细介绍了国内首例大面积采用真空-电渗降水-低能量强夯联合的软弱地基加固技术。此工程的成功应用说明,此方法在一定的复杂地质条件下进行软土地基处理,比传统的真空预压法具有一定的优势;检验结果表明,真空-电渗降水-低能量强夯联合软弱地基加固技术在地基处理深度要求不大,工期紧张且需要满足一定的承载力要求的地基加固中有一定的推广价值,同时也为电渗法广泛应用提供了强有力的技术支持。
Taking a project in Longxue Shipbuilding Base of China Shipping Company in Guangzhou as an example, the paper describes in detail the application of the weak soil improvement technology combining vacuum preloading, dewatering by electro-osmosis with low energy dynamic compaction to improve soft soils. The project was the first project employing the tech- nology combining vacuum preloading, dewatering by electro-osmosis with dynamic compaction to improve soft soils in large scale in China. The successful implementation of the technology on the project indicates that the technology has the advantages superior to the traditional vacuum preloading technique in treatment of soft soils in some complex geological conditions. The results of tests and measurements showed that the weak soil improvement technology combining vacuum preloading, dewatering by electro-osmosis with low energy dynamic compaction to improve soft soils doesn＇t demand high for the improving depth of soil and is worthy promotion in improvement of soils with a tight construction schedule, which demands some bearing capacity for the proceeding of the project. The technology may also provide potent technical support for the extensive application of the electro-osmosis technique.
