摘要
澜沧江西藏境内规划河段长317km，河流多年平均流量481—676m3／s，落差877m，水力资源丰富。但由于其地处青藏高原东南部的横断山脉，其区域构造稳定条件、工程地质条件极为复杂。本文在论述其基本地质条件的基础上，分析了水电开发存在的主要工程地质问题，希望对前期勘察工作有一定的指导作用。
The planned reach on Lancangjiang river in Tibet is 317km long, with a multi -year average flow ot 491 676 m3/s and a drop of 877m, where it is rich in water resources. Because its cross - sectional mountains are located in the southeastern part of Qinghai - Tibet plateau, its regional tectonic stable conditions and engineering geological conditions are extremely complex. The paper analyses the main engineering geological problems of hydro- power development based on the discussion of basic geological condition and hopes to have some guidance for pre - survey work.
