The Highway Slope Stability Analysis Of Reservoir Area

As the swift and violent development of high-grade highway in mountain area, many environmental problems affecting highway projects appear more and more obviously and the water disaster problem of highway is an aspect. Because of the interaction of environmental condition and water, all kinds of disasters happen to the highway along river and lakeside frequently, even lead to great water damage and cause personnel casualties and economic loss. The fluctuation of water height in reservoir area influences the stability of highway slope in this area or along reservoir side, therefore people cry for effective analysis method and prevention and cure ways to guard and reduce water disaster. In this paper, I take the expressway in Bailuo reservoir for example and discuss helpfully in these fields as follows:(1) Factors that affect the stability of highway in reservoir area have been analyzed, and the change of groundwater level with the reservoir water level fluctuation and rainfall has been discussed preliminarily. According to certain assumed conditions and utilizing the Laplace vary, the author deduced the calculate formula of the soakage line and utilized ANSYS to check analysis. Because the fluctuation of reservoir water level and rainfall may cause the fluctuation of groundwater level, we've found out the worst condition during the seepage flow and put forward some father advice which can provide strong foundation for choosing a better precaution and cure way.(2) Water-level fluctuation in reservoir area lead highway slope to be unstable. Through comparing a great many highway slope stability analysis methods, the optimal method suitable for Bailuo highway analysis has been determined and been used to analysis the Bailuo highway slope. According to the Bailuo highway slope analysis result, we have put forward a few suitable prevention and cure advice.(3) Through bank slump forecasting, this paper has summarized all kinds of modes of bank slump. Through comparing a great many bank slump forecasting methods, we have get the best way to forecast the Bailuo bank slump. According to the result we have put forward a few suitable prevention and cure advice.
