摘要
采空区的危害性评价是矿区高速公路建设技术难题之一。应用二维及三维有限单元法对某高速公路下伏一多层倾斜复杂地质条件老采空区的变形与稳定性进行了数值模拟。模拟计算结果表明,研究区多层倾斜采空区对路基的危害性严重,必须对公路路基影响范围内的采空区部位进行处治。
Hazard potential evaluation of regions underlain mined caverns is one of difficult technical problems in highway engineering. Two- dimensional and three- dimensional FEM are applied to evaluate the hazard potential of underground mined caverns to the highway on their above ground. The underground caverns are multi - layered and inclined. The numerical results show that the mined caverns have potential hazards to highway. The affected zone along the highway must be improved.
