天生桥一级水电站泥岩工程地质特性

Mudstone's Engineering Geological Feature of Tiansheng Qiao-1 Hydroelectric Project

天生桥一级水电站坝区泥岩分布广泛，地下、地表工程的开挖都大量涉及到泥岩。本文对泥岩的矿化成分和力学性质进行了室内试验和现场测试成果分析。

The mudtone is distributed widespread on the dam area of Tian sheng Qiao-1project,which is involved largely during the excavation of underground and surface project.So,the tests have been performed indoor and on the dam site on the mudstone's mineral andchemical composition and the property of mechanics This paper introduces the engineeringgoeologic property of the mudstone on damsite,and provides basis for the supporting designand the construction mehod.
