摘要
针对桥梁基础在洪水冲刷侵蚀下容易丧失稳定性的情况,采用嵌入基岩防护墙对某桥梁基础进行防护,用钢板桩围堰临时支护基础,砂袋围堰支护外侧水土施工,安全好省地解决了桥梁基础的冲刷病害,同时保证了河道的泄洪能力。
Because bridge foundation easily loses stability under flood erosion, the protective reinforced concrete wall embedded into bedrock is taken to protect foundation. Moreover, temporary steel sheet pile and sand bag cofferdam is taken to support the unstable foundation. This method can treat erosion disease of bridge foundation safely and cheaply, and ensure the river＇s flood discharge capacity at the same time.
