Problems solved by technology

However, the slope aspect parameters of dangerous ice bodies that have an important impact on the outburst of moraine lakes are not considered, which has a greater impact on the judgment of the susceptibility of moraine lake outbursts without buried ice
In addition, each influencing parameter is in a different range of values, and its influence is different, and the final result will affect the accuracy of susceptibility judgment

Abstract

The invention discloses a method for judging the outburst susceptibility of a moraine lake without moraine embankments, which belongs to the technical field of water conservancy projects, and is characterized by comprising the following steps: a, judging whether the moraine lake is a moraine lake without moraine embankments; b, basic parameters of a moraine lake without moraine embankment burying are determined through the Google Earth; c, carrying out standardization processing on the basic parameters, and calculating a susceptibility comprehensive discrimination factor P of a moraine lake without buried moraine embankment; and d, judging the susceptibility according to the susceptibility comprehensive judgment factor P of the moraine lake without the moraine embankment. The moraine lake outburst mechanism of the moraine-free embankment and the potential ice collapse body are researched, standardized data are adopted, the influence of different parameter value ranges is removed, comprehensive judgment is made, the moraine lake outburst susceptibility of the moraine-free embankment can be effectively determined, and the accuracy of the susceptibility judgment result is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering, in particular to a method for judging the susceptibility to burst of a moraine lake without a buried moraine embankment. Background technique [0002] Ice and cement flow is a natural phenomenon that occurs in the distribution area of ​​alpine ice and snow. Ice and cement flows often occur due to the rise of local temperature, the melting of ice and snow to form channel runoff, start the solid source in the channel, and form ice and cement flows. The formation of ice and cement flow requires two conditions: one is the terrain conditions that are conducive to the occurrence of ice and cement flow; the other is certain temperature conditions that lead to the melting of ice and snow and eventually induce the occurrence of ice and cement flow. These conditions combine to determine the likelihood of ice and cement flow occurring. Among them, the impact of terrain conditions on ...
