| The trail dam is the important establishment in the mine production,which status influenced on safety of people' life and property. But its wreckage is mostly due to water. So the research of its stability is significant.The thesis built the relation between containing water and the properties of trail dam's soil by geomechanical properties of trail dam's soil;analysed the seep rule of water in the trail dam's field and the change of soakage line . The thesis applied the limited element to analyze the trail dam of BAOGANG by the engineering item in production . It calculates the dynamic and static response about the dam using the numerical simulation method. At last,gave the proposal to reinforce. |
