| Abstract: | Karst is strongly developed along the Yichang-Wanzhou railway.On the basis of the characteristics of dissolved cavity from DK203+060 to DK203+110 section of Yichang-Wanzhou railway and on the consideration of gravity and train load,the numerical simulation is applied to analyzing the distribution of the tensile stress around dissolved cavities with different kinds of top plate thickness and diameters.The research result has reference significance for stability analysis and dissolved cavity treatment. |
