摘要
针对在杭浦高速公路建设工程软土地基处理方案中,由常规水泥土搅拌桩被否决到双向水泥土搅拌桩被采用的变化过程,通过试桩施工,试桩桩身强度试验成果对比及理论分析和经济对比,介绍了双向水泥土搅拌桩及其施工工艺;同时论述了双向水泥土搅拌桩优越的工程特性及其良好的社会经济效益。
In the soft ground treatment scheme of Hang-Pu expressway construction project, the traditional cement-soil mixing column is rejected and the bi-directional one is accepted. Through contrast and theoretical analysis of column strength test result from trail construction of columns, this paper introduces bi-directional cement-soil deep mixing column and its construction process. This paper also states superior engineering characteristics and good social and economic benefits of hi-directional cement-soil mixing column.
