对于跨河桥梁,桥梁结构安全风险因素除了超载外,超标洪水对桥梁冲刷是跨河桥另一重大隐患。大量桥梁水毁实例资料显示,跨河桥在超标洪水作用下易出现基础冲刷掏空导致桩基承载力不足、板式橡胶支座滑移导致桥梁错位、上部结构直接漂浮... 对于跨河桥梁,桥梁结构安全风险因素除了超载外,超标洪水对桥梁冲刷是跨河桥另一重大隐患。大量桥梁水毁实例资料显示,跨河桥在超标洪水作用下易出现基础冲刷掏空导致桩基承载力不足、板式橡胶支座滑移导致桥梁错位、上部结构直接漂浮滑移、上部结构直接横移倾覆等桥梁失效形式。因此,以合肥市南淝河上4座重点跨河桥为例,对桥梁在超标洪水下的的失效形式进行分析,以期为同类型桥梁在洪水状态下的失效形式分析提供参考。 展开更多

It is an important task for underground mine to guarantee its safety during the flood season. The authors analyzed the status of water prevention and control in Chengchao Iron Mine,China,and put forward the necessary measures. The hydrogeological parameter controls the design of mine water prevention and affects the mineral well safety in operation. Enhance supervision and control,keeping the current facilities intact,using the existing pump house and the underground tunnel to adjust and control the amount of water and improving the hydrogeological conditions in the mine are the practical and remedial measures. 展开更多
