Zhunchi Overloaded Railways Loess Subgrade Slope Stability Analysis

Recently years,with the developing of our modern social construction day by day.The traffic demands have played an important role in our daily life.As the high-speed railway on behalf of Chinese technology almost indispensable tool in China.Actually the heavy haul railway also has given enough attentions by our Chinese government.When it comes to the problems of slope stability.Here are some important issues we should pay attentions on it.Because it is very important significance on the construct railway or the highway.lt is concerned about the problem of safety construction and operation. Therefore,proper pertinent measures must be taken to the research and explore of the slope stability.This article mainly do some in-depth researches on the loess subgrade slope of Zhunchi Railway.Based on the meticulously researches and explores to the weather conditions,hydrologic information,geographic situations to analysis the loess subgrade slope stability.Obviously,in older to find out the reasons of destroy,we use computer simulation by the way of finite difference method,such as FLAC 3D to do the loess slope,so as important as the former.Finally,this article gives a comprehensive conclusion about the issues of the some methods and preventive actions.In this article, the main research contents:1.According to the limit equilibrium method (It can be calculated the safety factor of some dangerous slopes for comparison)involves the method of Fellenius,which do some exactly analysis and considerations on the loess subgrade slope of Zhunchi Railway.2.Using the method of FLAC 3D (finite difference method simulate the computer three-dimensional simulation to the loess subgrade slope of the Zhunchi Railway).In addition,the FLAC 3D not only gives us some exactly and properly information about stress nephogram,level vertical displacement nephogram and shear strain nephogram,but also make an analysis proper about slope instability,shear displacement and transformations under the different conditions.Meanwhile,this article successfully find some main factors about the destroy of the labeled loess slope by the analysis of its subgrade slope stability.3.From what we have discussed above the article can draw the conclusion about the main destroy factors about the labeled loess subgrade slope by means of some researches analysis and even the simulations to the destroy of the loess subgrade slope,and then the main factor is,it is essential to include the crack condition in the stability analysis of expansive soil slope with rainfall infiltration.To sum up,this article shows us,considering all of possible factors.In the writer’s opinion,a more practical way to solve the problem of the labeled loess slope destructive effects.Only in this way can we create a properly protection scheme to the loess subgrade destruction.Of course,proper measures must be taken to blend vegetation protection with engineering protection,proof by the writer’s facts,both of them are the best cure for the loess slope protection.
