Evaluation of Slope Stability by the In Situ Monitoring Data Combined with the Finite-Discrete Element Method

We examine the stability of an ancient slope located at Jietai Temple in western Beijing of China, by using the remote monitoring system of sliding force combined with the combined finite-discrete element method (FDEM) as well as the field surveys. Potential pre-existing joints in the slope were firstly determined by the in situ study and rock mass mechanical properties were then estimated to be taken as input parameters in the numerical modelling, for understanding the instability mechanism of the slope. Results from this synthetic assessment together with the monitoring data suggest that current protection measures in the slope may not be sufficient so that the local authorities should define hazard zones and work out further development plans for the Jietai temple.
