摘　　要：刚性防水是比柔性防水更早使用的一种防水形式,其具有耐久性长、原料来源广泛、方便传统施工等优点,一直沿用至今。最近征求意见的《建筑与市政工程防水通用规范》要求地下工程防水工作年限与结构主体相同,再次引起关于柔性防水与刚性防水耐久性的讨论,相关部门也正在编制有关刚性防水与混凝土结构自防水的一些标准。本文提出了"刚性防水体系"的概念与系统性分类,以及与此相关的"刚性防水层"和"结构自防水"的技术论述,供大家讨论与后续标准编制参考。As an earlier waterproofing form than flexible waterproofing,rigid waterproofing has the advantages like long durability,wide raw material source,convenient traditional construction etc.,and it is used up to today.“General specification of municipal engineering waterproof”,which is soliciting public opinions recently,requires that the working life of underground work's waterproofing should be in line with that of the main structure.This triggers a discussion on the durability of flexible and rigid waterproofing again,and relevant departments are preparing some standards for rigid waterproofing and concrete structure self-waterproofing.This article puts forward the concept and systematic classification of“rigid waterproofing system”,relevant technical discourse of“rigid waterproofing layer”and“structure self-waterproofing”as well for public discussion and the reference of subsequent standard establishment.
