户宋河电站全风化闪长岩工程地质特性

Engineering Geological Properties of Completely Weathered Diorite in Husonghe Hydropower Project Area

在滇西、滇南花岗岩分布区常有较多闪长岩脉，所勘测的工程如景洪电站、户宋河电站等均有出露。本文主要就户宋河电站工程在闪长岩地段勘测、施工中反映出的工程地质问题，做一归纳总结，以期对类似工程有所借鉴。

Many diorite veins usually outcrop in the granite areas in west Yunnan and south Yunnan, which have also been found in such hydropower project areas as Jinghong and Husonghe hydropower project areas. This paper summarizes the engineering geological problems encountered in the diorite zone of the Husonghe project area during geological in_ vestigation and construction of the project with the intention of providing experience and lessons for other similar projects.
