摘要 地下工程在施工和使用过程中,时刻都受到地下水的危害。杜绝水对地下工程的危害,是地下工程设计和施工的重要课题。本文介绍了国内外地下工程防水技术的发展状况和存在的问题。概述了围岩防水、结构自防水、附加防水层以及排水系统等防水技术,总结了地下工程细部构造和外墙施工缝、后浇带以及变形缝细部构造处理及施工方法。并从结构自防水、自防与附加层防水相结合、新防水材料的应用以及施工工艺几个方面对地下工程防水技术作了进一步展望。 Underground engineering is constantly threatened by groundwater during its construction and in use.It is a key topic to completely eradicate the danger of water to underground engineering in design,construction and use.The paper presents the recent development and existing problems of waterproof techniques on underground engineering in China and foreign countries from a viewpoint of design,construction,application of new materials and maintenance.It sketches out such waterproof techniques as waterproof of surrounding rock,self-waterproof of structure,additional waterproof layer and drainage system,summarizes the design principle on details of underground engineering and structure treatment and construction method of outer wall joint,post-pouring concrete strips and details of deformation joint.Finally,it looks into the prospect on waterproof techniques in the future in such aspects as self-waterproof,association of self-waterproof with additional waterproof layer,application of new waterproof materials and construction technology.
