宿州市埇桥区王桥闸防渗排水设计

Anti-seepage and drainage design of Wangqiao Sluice in Yongqiao District,Suzhou City

王桥闸是沱河上的水闸之一,担负着输送附近城镇居民生活及农业用水的任务。由于水闸的基面直接与砂壤土接触,且砂壤土渗透系数较大,故实际设计过程中闸基的防渗排水尤为重要。采用改进阻力系数法及Autobank软件对闸基的渗流稳定进行计算,详细介绍了水闸的防渗排水设计成果,可供类似水闸防渗设计参考。

The Wangqiao sluice is one of the sluices on the Tuo River,which is responsible for transporting water for the residents of nearby cities and towns and for agriculture.Since the base surface of the sluice is in direct contact with the sandy loam soil,and the sandy loam soil has a large permeability coefficient,the anti-seepage and drainage of the sluice foundation is particularly important in the actual design process.This paper uses improved drag coefficient method and Autobank software to calculate the seepage stability of the sluice foundation,and introduces the results of the anti-seepage and drainage design of the sluice in detail,which can be used as a reference for the anti-seepage design of similar sluices.
