越江管道下穿的防汛墙结构设计

Structural Design of River-crossing Pipeline across Flood Control Wall

重要的越江管道关乎人民的生命和财产安全,越江管下穿防汛墙的布局屡见不鲜。以上海市两条越江供水管道为例,根据越江管道相关的保护规定,划定其两侧的控制范围和保护范围;分别采用优化的桩基承台结构和原状土地基处理的方式,给出管道下穿范围防汛墙的结构设计方案,并采用圆弧滑动法验算了结构的合理性。为类似的防汛墙设计,提供一种思路和方法。

The important river-crossing pipelines concern the life of the people and the safety of property.The layouts of river-crossing pipeline across flood control wall are common.Taking two river-crossing water supply pipelines in Shanghai as the examples,based on the relative protection stipulations of river-crossing pipeline,the control range and protection range at the both sides are delimited.The optimized pile foundation base slab structure and undisturbed soil foundation treatment modes are respectively used to give the structural design schemes of pipeline across flood control wall.The structural rationality is checked and calculated by the circular slide method.The thinking and method are provided for the design of similar flood control walls.
