摘要
深厚层大面积软土地基处理及其工后沉降控制一直是国内外岩土工程及地下工程研究领域的难点问题。以福州江阴港铁路支线浅海区大面积深厚软基层处理工程为背景,通过试验提出采用塑料排水板联合水泥土搅拌桩、超载预压排水固结法、真空加堆载联合预压排水固结法等3种软基处理工法进行综合处理,详细介绍了这3种工法的施工工艺流程、技术要点和关键技术措施,综合处理效果显著。
Large area processing on the deep layer and the post-construction settlement of soft ground control have been a hot and difficult issue in geotechnical and underground engineering fields all over the world. In this paper, Fuzhou Jiangyin Port Rail Line, which is to be built on a large area of shallow sea, is taken as the engineering back-ground. Through experiments, 3 soft foundation treatment methods are used for the comprehensive construction, they are.. plastic drainage plate ＋ soil cement mixing pile; over-loading preload consolidation and vacuum preloading ＋ heap drainage consolidation. Then, the details of three construction methods and their construction processes, the technical points and key technical measures are introduced. This integrated treatment proves to be effective in compre-hensive ground treatment.
