海拉尔至满洲里一级公路部分路线穿越海拉尔河漫滩湿地,软土层位于地表,厚度较薄,而且地下水位较高,综合考虑施工难易以及经济效益,提出了强夯置换墩复合地基的设计方案。为验证该方案的适用性,通过试验区的试夯试验,确定了施工参数,并结合实际工程对其设计要素及施工要点进行了介绍,同时验证了强夯置换法用于处治这类湿地地基的合理性。 The part of Hailar-Manzhouli Highway runs through the Hailar floodplain wetland. The soft soil layer is located on the ground surface, with a relatively thin thickness and a high groundwater level. Considering the construction difficulty and economic benefits, a design scheme of dynamic compaction displacement pier composite foundation is proposed. In order to verify the applicability of the scheme, the construction parameters were determined through the test-ramming test in the test area. The design elements and construction points were also introduced in combination with the actual projects. At the same time, it was verified that the dynamic compaction displacement method was used to treat such wet-ground The rationality.
