Stability Monitoring Controlling and Application to the Excavation System of Slope Engineering in Geheyan Hydraulic Power Station

The dynamic monitoring controlling method is successfully used to the safty monitoring and forecasting in the process of slope excavation for the high slope of Geheyan Hydraulic Power Station in Qingjiang River. The paper firstly studies and analyzes the engineering geology, excavation circumstances and the characteristics of safty monitoring system, and then discusses the forecast method of the loss of stability of slope, application of forecast, dynamic controlling of excavation quality and excavation sequences. Above research work embodies the dynamic ideas of system design, construction and monitoring controlling of slope engineering.Good practical results are achieved in field.
