摘要
水泥土搅拌桩作为一种常用的地基处理手段,能有效提高地基承载力,较好地控制工后沉降,但是其施工质量管控一直难以较好解决。以杭州绕城西复线湖州段软基处理工程为依托,开展了基于搅拌桩施工远程监测系统的应用研究,实现了搅拌桩的信息化施工和全过程管控。基于监测数据和现场标贯试验,对几种典型的搅拌桩施工工艺进行分析,为搅拌桩施工提供指导意见。
As a commonly-used ground improvement alternative,deep mixing method can effectively increase the bearing capacity and reduce deformation of soft clays.However,quality control has still been a problem and there has been limit effective measure in practice.An application of remote monitoring system of deep mixing construction process is introduced,which is used in the ground improvement project at Huzhou Section in Hangzhou beltway,realizing real-time tracking and feedback of data during construction.Based on the monitoring data and standard penetration test,some kinds of typical construction method in the field were analyzed,and some guidance was offered for construction.
