摘要
印尼拉里昂彼力水电站工程位于Lariang河上,工程区位于Palu-koro断层影响带内.文章主要根据试验数据,从岩石矿物成分特性、岩体宏观结构特性、场区地质构造特征三个方面,分析二长花岗岩强度异常的原因,为今后在高烈度地震区分析坝基岩体提供有效的分析方法.
Abstract
The Lariang Pili hydropower station project in Indonesia is located on the Lariang River,and the project area is within the Palu koro fault zone.Based on experimental data,this study analyzes the reasons for abnormal strength of diorite granite from three aspects:rock mineral composition characteristics,macroscopic structural characteristics of rock mass,and geological structural characteristics of the site.This provides an effective analysis method for analyzing dam foundation rock mass in high-intensity seismic areas in the future.
