Stability Analysis of Sinkhole Considering Groundwater Level Fluctuation

Abstract:

Article Preview

The Method of Finite Element Method Strength Reduction is used to numerical calculate and analyse the subgrade with soil cave, by considering the influence of groundwater level fluctuation in its stability. Nondimensionalize the effect factors, and draw the stability curve to get the regression curve, then make the result regression coefficient directly to the project cases. The result shows that under the weight of the subgrade, the subgrade with soil cave is damaged by that the soil around the soil cave is sheared. The more the value of is, the larger the stability coefficient is, and the higher groundwater level is, the better the stability of the subgrade with soil cave is. With the value increases, the region of stability expands
