Abstract:A typical example argillite bedding landslide at the K31+160–K31++460 of Changzhi to Jincheng highway is presented. By using numerical simulation software Geoslope,the states of slope under the full face excavation without engineering protection on the original design and the effectiveness of reinforced slope after design changed are simulated. The updating status of reinforced slopes after design changed is being monitored and analyzed. It provides the scientific basis for dynamic designing,information construction of landslide combing numerical simulation with monitoring analysis based on comprehensive updating recuperation. Finally the successful control practical experiences show:(1) controlling landslide does not only consider resistive engineering,but also enhance discharge underground water that influence the weak interlayer of landslide;(2) the method by controlling the landslide that combing the numerical simulation reflecting the integrality stress and strain with the monitoring information of several key points of the whole slope can propose a new method for complex landslides reasonable design and successful control.
