Present situation and preliminary analysis of glacial lake in naqu region

Abstract

The location of glacial lake is special and the results of previous researches are few. But it has caused a lot of geological disasters in its history, and been an urgent need to solve the engineering problems. Based on the historical data and a large number of field visits, the principle of the glacial lake disaster is analyzed, in combination with the first-hand data obtained from the site survey, the complexity of the glacial lake disaster mechanism is explained. It is believed that taking the glacier, glacial lake and the downstream rivers into consideration together is the key to solve the problem. This paper analyzes the possibility of glacial lake for hydropower generation, water diversion and water conservancy scenic area, and so on. On this basis, it proposes that the safety risk assessment is the basic work for disaster prevention and mitigation of glacial lake and their development and utilization.
