Abstract

For ground freezing and pile-support deep foundation pit of south anchorage of Runyang Bridge, ground freezing made the mechanic state of foundation pit become complex. Monitoring is timely monitor construction quality, and provide accurate science research data, found hidden danger etc. Through monitoring, we can momentarily master its stability status, found instability factors and adopt measures.The large safe monitoring system was built, based on the output of three-dimension finite element simulation. Analysis the change rule of several kinds of monitoring data, and the feedback analysis was made based on the construction monitoring, guarantee the safety and stability of ground freezing and pile-support deep foundation pit of south anchorage.
