公路桥梁桩基冲刷加固方案比选及应用研究

Study on scheme selection and application of scouring reinforcement for pile foundation of highway bridge

以某高速公路桥梁桩基冲刷加固为例,制定了水下玻纤套筒和钢套筒的两种加固方案,并对其进行了对比分析。分析结果表明,桥梁桩基冲刷类病害采用水下玻纤套筒的加固法更为有效,且方便施工,造价经济。

Taking the scouring reinforcement of a highway bridge pile foundation as an example,two reinforcement schemes based on underwater glass fiber sleeve and steel sleeve are formulated,and the reinforcement scheme is compared and analyzed.The analysis results show that for this type of bridge pile foundation erosion disease,the use of underwater glass fiber sleeve reinforcement method is more effective,convenient for construction,economical in cost.
