摘　　要：渠道工程都修建在不同的岩土体上,这些岩土体的稳定性,即渠基及渠坡的稳定是保证渠道安全运行的前提和关键。因此,在渠道衬砌与防渗工程建设中,必须根据渠道岩土的工程性质、渠道类型、渠道工程级别和规模等条件,采用适宜的工程措施,增强渠基及渠坡的稳定,以保证渠道工程安全运行。本文概述了国标《渠道防渗工程技术规范》"渠基与渠坡的稳定"一章的修编思路。针对行业规范升级为国标规范的需要,对该章内容做了一定调整,并补充了较多内容,包括:将原章名"渠基稳定"改为"渠基与渠坡的稳定";增加了"渠坡的安全坡比"和"沙漠渠道"两节;在特殊土(黄土、膨胀土、分散性土、盐渍土、冻胀性土和沙漠土)渠基与渠坡的加固处理方面增加了新技术、新材料和新方法应用等内容。Since canals are usually constructed on different types of rock bodies,the stability of rock bodies has become a key issue to ensure safe service of these projects.Therefore,in canal lining and seepage prevention for canals,it is necessary to take proper measures to reinforce the stability of canal foundation and slope so as to ensure the safety of canal engineering according to the engineering properties of rock,canal type,grade and size.This paper summarized revising and compiling of the chapter ＂Stability of Canal Foundation and Slope＂ of GB Technical Specification for Seepage Prevention Engineering on Canal.In view of the upgrade need from an industrial specification to a national specification,proper content adjustment was made and more content was introduced.These revisions included the chapter renaming from Canal Foundation Stability to Stability of Canal Foundation and Slope,introducing ＂Safety Factor of Slope＂ and ＂Desert Canal＂ as two sub-sections.In addition,some advanced technologies and new materials and new methods were introduced for reinforcement of canal foundation and slope of special soils （such as loess,expansive soil,dispersive soil,salted soil,frozen soil and desert soil）.
