矩形涵洞桥在灌、涝区工程配套中是一种常见的水工建筑物。在矩形涵洞桥的设计中,两侧挡土结构设计是不可缺少的一项,在过去的设计中,常以浆砌块石或素混凝土做成较笨重的重力式挡土墙,或者采用悬壁式钢筋混凝土结构挡土墙。这种设计方法在缺少砂石料地区,由于工程量大,显得工程既不美观又不经济。在矩形涵洞桥挡土结构设计上,我们在实践中探索出一种新的优化设计模式,这种设计模式的优点是:工程量小、省资金、抗冻害性能强。
Rectangular culvert bridge in irrigation, waterlogging area project is a common hydraulic structures. In the design of rectangular culvert bridges, the design of retaining structures on both sides is an indispensable one. In the past design, it was often used as a clunky gravity retaining wall made of masonry or plain concrete, or suspended Wall Reinforced Concrete Retaining Wall. This design method in the absence of sand and gravel region, due to the large amount of engineering, it seems that the project is neither beautiful nor economical. In the design of rectangular culvert bridge retaining structure, we explore a new optimization design pattern in practice. The advantages of this design pattern are: small amount of engineering, provincial capital, antifreeze performance.
