Abstract: Low elastic modulus concrete anti-seepage wall was applied in resk removal and consolidation design of Qingshan reservoir, Tongjiqiao reservoir and Laohutan reservoir projects, etc.. Based on them, the paper was put forward major performance indexes of the wall material, major ideas and the related matters which should be considered in designing of proportion ratio. Therefore, significant experiences were obtained to use low elastic modulus concrete anti-seepage wall technology for risk removal and consolidation of similar high core wall earth-rock dam and low and medium slab rockfill dam.

摘要： 通过青山水库除险加固、通济桥水库除险加固和老虎潭水库等工程中低弹模混凝土防渗墙的设计应用，提出了墙体材料的主要性能指标和配合比设计时应考虑的主要思路与须关注的一些问题，为今后类似高心墙土石坝除险加固和建在覆盖层基础上的中低面板坝中采用低弹模混凝土防渗墙技术提供了一些借鉴。
