某钢铁厂拟建场地在越南沿海,覆盖层为海洋沉积物、表层为近期人工吹填砂。为给主体建筑建设提供场地,同时减少场地工后沉降对建筑物桩基的影响,针对软土地基进行了加固处理。工程选择采用真空预压法加固,通过优化工艺流程及参数、控制重点工序,取得了较好的效果与效益。
A steel plant to be built on the site of the Vietnamese coast, covering the marine sediment, the surface of the recent artificial sand filling. In order to provide the main building construction site, at the same time to reduce the post-construction settlement of the pile foundation, for soft ground reinforcement. Selection of projects using vacuum preloading reinforcement, by optimizing the process and parameters, control key processes, and achieved good results and benefits.
