澜沧江某水电站左岸地下式厂房岩体质量分级

ROCK MASS QUALITY CLASSIFICATION OF UNDERGROUND BUILDING ON THE LEFT BANK IN A HYDROELECTRIC STATION ON THE LANCANG RIVER

通过大量的现场调查数据与统计工作结果,采用了多种岩体质量分级评价方案,对澜沧江某水电站左岸地下式厂房岩体质量进行了精细的评价,最后将各种结果进行对比分析,得到一个合理、科学的综合岩体质量综合评价分级。并根据评价结果,作出了研究区坝址左岸地下式厂房岩体在不同高程的岩体质量分区图,为下一步的参数选取工作奠定了必要的基础。

Based on the abundant field investigation and statistical data , some different types of classification methods for rock mass quality are used in this paper to evaluate the rock mass quality of the underground building on the left bank in a hydroelectric station on the Lanchangjiang river . Finally , by contrasting and analyzing those result , a reasonable and scientific achievement is obtained . Based on the evaluation results, zoning maps of rock mass quality of left bank at different levels are made, which will benefit the succeeding work.
