| China is one of the countries where many load hazards happens frequently in the world. Every year the destruction brought by landslide causes a massive loss for national and people's life and property. In order to carry out the sustainable development concept proposed by government and insist on the humanist idea, based on the spirit of "eleven five year" plan that the road disaster should be reduced and the road condition should be improved year by year which was proposed by Department of Transportation, the load hazards of 316 State Road in Shanxi province are treated. In the paper, through the generalized analysis on actual situation of 316 State Road landslide, the corresponding treatment method is proposed, which can provide experiences and reference to this kind of landslide. There are two key points in the paper.1. Because growth of the road landslide has its own characteristic, such as distributing along the route, large density in local area and the similar growth theory of many landslides. According to these characteristic, methods are proposed, which are combined by five plans, i.e. "Drainage, Retaining Wall, Reduce the pressure, Reinforcement and Tree Planting" so that the hazards are reduced or avoided as much as possible.2. In the paper, according to the type, scale, forming theory and the present improvement situation of 316 State Road landslide in Shanxi province, Imbalance Thrust Force Method is chosen to calculate the landslide stability. Through the accuracy analysis, surplus thrust force of landslide obtained by this method is smaller than the actual value .Because the landslide often happens after continuous rainfall, especially after big rainstorm. The rainfall may make the density of soil bigger and internal friction smaller. The method chosen above has not taken into account the influence of the change of density of soil and internal friction occurred after rainfall. Therefore, Imbalance Thrust Force Method need to be modified in order to make the thrust force design value of landslide calculated more tally with the actual situation. The corrected value is mainly based on effective rainfall amount. |
