| 摘 要： | 为防止出现过大的工后沉降和缩短软基处理后结构物施工的间歇时间,对结构物基础施打预应力混凝土管桩处理,并利用砂井桩的排水固结和土工格栅的纵横向联系而形成复合地基,以达到软基加固和缩短预压时间的目的。

| Abstract: | In order to prevent serious after-work settlement and cut down the intermittent time of structure construction after treatment of soft foundation, prestressed concrete pipe piles were adopted for foundation treatment of structures, to form composite foundation with sand piles and geogrid, so as to strengthen soft foundation and shorten preloading duration. |

| Keywords: | settlement pipe pile strengthening preloading duration |
