浅谈涵洞式水闸设计中的几个问题

涵洞式水闸常修建在挖方较深的渠道中填土较高的坝堤下，由于抗滑稳定能得到保证，所以期设计常易被人忽视，使得水闸在运行中经常出现底板不均匀沉陷，洞身段产生裂缝、渗漏现象，造成地基渗透变形等不良后果，严重时会威胁水闸及堤防的安全，文章以涵洞式水闸设计中的水力计算及泄水、渗流产生的影响进行了探讨。

Discussion About Some Quetion of Clough Ddesigh

Cloughs are usually built in relatively clough deep canals or beneath relatively high dickes .Becaus their slip-resistance and stability can be guaranteed.their designs are often carless. Consequently unequal settlement. cultvertc rack and leakage often ocurded in some cloughs during operation and broaght about percolation in and deformation of foundations.Whenthese were severe the safety of cloughs and dickes was threatened.In this paper I show you some of my studies on waterpower calculation and effects produced by sluicing and percolating flow in clough design.
