砌石拱坝的自防渗体系研究

A Study on a Self-seepage-controlling System of Stone Masonry Arch Dam

本文介绍了一种新型砌石拱坝防渗体系：用明矾石微膨胀混凝土浆砌块石做壳体，配合粉煤灰细石混凝土埋石填筑构成的砌石坝自防渗体系。通过对其运行机制、性能、造价等方面的分析，阐述了该体系较传统砌石坝防渗体系的优势所在，供类似工程参考。

A new kind of system of stone masonry arch dam for seepage control is introduced as an engineering example.A self-seepage-controlling system of stone arch masonry dam is stressed.The shell body of this kind of dam is made of alumite weak-expanding mortar and its inter part is made up of rubbles packed with powder coal ash mortar.By the analysis of its machanism、function and cost,its advantages than the traditional stone masonry dam are expounded,and the results are provided here for consideration in similar projects.
