Abstract: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.
