| Abstract: | The case of the perilous rock belt of Miaoziliang, which located in the region of the Three Gorges Reservoir, was analyzed quantitatively according to the system of indices. The sensitive elements affecting the rock belt was studied by means of Uniform Design Method, and then the regress equations and ascertaining the partial correlation coefficient of stability as well as the main control factors were detected. It also evaluates the relative contribution to stability and optimizes the local condition parameter with Grid Experiment Model, which assesses the optimum and the worst case rate combination. Aimed at the foregoing discussion, the concrete measures had been put forward. |
