Study On The Reinforing Project Of Hualin Highway Slope And Its Stability Analysis

Soil slope is a kind of slope. According to the trait of the soil slope, combining the traditional soil-nailed reinforcement with pre-stressed anchor-pole reinforcement, I obtain a new reinforcement structure of the soil slope-----pre-stressed anchor-pole & soil-nailed reinforcement structure, this is the composite soil-nailed reinforcement system. I'll design a reinforcement structure for a soil slope in the practical engineering. The main contents are as follows:1. I introduce the reinforcement structure-----soil nail & pre-stressed anchor-pole reinforcement structure, that is composite soil-nailed reinforcement structure.2. I expound the soil-nailed reinforcement technic and anchor-pole reinforcement mechanism. I dissertate the earth status of the soil slope after reinforcement and soil-nail, anchor-pole and the earth effects with each other. At last, I make clear that soil-nail and pre-stressed anchor-pole have the different function for the stability of the soil slope.3. I compute the soil nails used in the slope with the software of soil-nailed wall design. At the same time, I check the stability of the natural slope and the slope after reinforcement.4. Using the soil nail FEM system, I do a numerical simulation in order to analyze the deformation of the soil slope after reinforcement. By the numerical simulation, I attain a conclusion that the deformation of the soil slope after reinforcement rangs in a permited extension and the soil slope can keep stable for a long time. This reinforcement structure is reasonable and is thought to satisfy the need of the engineering practice.By the test of the practical engineering, I can say that soil-nail & pre-stressed...
