挡土墙优化设计与风险决策研究——兼述黄壁庄水库副坝混凝土生产系统的挡土墙建设实践

Optimal Design & Risk Decision Making in the Abamurus Construction of Concrete Production System at the Huangbizhuang Reservoir Secondary Dams

挡土墙作为一般土建工程的拦土建筑物常用在闸坝翼墙和渡槽、倒虹吸的进出口过渡段,它的优化设计问题常被忽视。实际上各类挡土墙间的技术和经济效益差别是相当大的。而一些工程的现实条件又使一些常用挡土墙呈现出诸多方面局限性。黄壁庄水库除险加固工程的混凝土生产系统的挡土墙建设在优化设计方面向前迈进了一步,在技术和经济效益方面取得明显效果,其经验可供同类工程建设参考。

Abamurus is commonly constructed in the transition sections of dam's wing-walls, aqueducts and outlets of the inverted siphon, but it' s optimal design is often neglected. In technical and economic benefit respects, big differences varies based on various types of abamurus after considering the limitation of abamurus in the construction sites. The practices in the Huangbizhuang Rerservoir strengthening project has made noticeable progress at the optimal design, which can be used by the similar program.
