1 引言斜尔尕枢纽是南水北调西线工程大渡河调水方案的比较枢纽之一,最大坝高252m,总库容47.56亿m~3,年引水量50亿m~3。水库的修建,将会使一定范围内的自然平衡状态发生改变,引起地质环境的异常变化,诱发一系列的环境工程问题,而这些环境工程地质问题的发生、发展将直接或间接地影响到水库工程的正常运用以及水库周边的工农业生产。本文从水
1 Introduction The Qian’er Project is one of the comparative hubs for the Dadu River water diversion project in the Western Route of the South-to-North Water Diversion Project with a maximum dam height of 252m and a total storage capacity of 4.756 billion m 3 and an annual water diversion volume of 5 billion m 3. The construction of reservoirs will change the natural balance within a certain range, causing abnormal changes in the geological environment and inducing a series of environmental engineering problems. The occurrence and development of these environmental engineering geological problems will directly or indirectly affect the reservoir The normal use of the project and the industrial and agricultural production around the reservoir.
