The Rock Slope Of River Port Stability And Support Simulation Analysis In Mountain Area

The rock slope of mountain river port marked by the seepage . the sharp movements of river level can cause the groundwater flow slope ,which formed a certain gap. Under the influence of the seepage field, stress field of rock slope also will change. Those factors makes the rock slope under continuous fluid-solid coupling effects. Therefore, the analysis of fluid-structure interaction effects on the rock slope is important to improve the stability of rock slope theory, and can in practical engineering to provide a theoretical guide. During the excavationof rock slope, excavation unloading produced rock slope caused by stress redistribution, the stability of rock slope will be some impact. Therefore, during the excavation it is necessary to analyze slope stability, and poor slope stability measures should be taken by some support.The main contents are as follows:1, The paper give a detailed analysis about the current flow of the two main simulation methods (limit equilibrium method and the finite element method) . According to the characteristics of slope stability analysis port on the analysis model were derived, the suitable mathematical model was established; on the existing slope stability analysis and finite element ultimate strength strength reduction was compared, the calculation of coupling analysis was deduced, and the calculation of the parameters of the process of selection criteria was given .2, The paper combined with large transport terminal in Changshou the specific hydrogeological conditions, the numerical simulation was analysed. Computing model was based on data obtained from field geological exploration, the conclusion was obtained by analyzing the rate of change with the increase of water level, which slope sliding body gradually developing in depth, and resulting displacement is also growing.3,The sliding trend of landslide slope was different changes in within and outside backwater areas, slippery slope slip region can produce a displacement is gradually decreased from the peak to 0. The backwater areas of change, the slope slide from the peak experience of mutation to 0.4, Describes the slope engineering involved in the anchor bolt of the classification and supporting design methods. Excavate the rock slope step by step, and excavate one step then support this step, Use strength reduction of the excavation process of a comprehensive simulation and fully reflects the rock slope at the edge of the excavation process while retaining the displacement variation of safety factor variation...
