Research on Construction Methods of Deep Mixing Column Based on Remote Monitoring System

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.
