Pregnant Environment Analysis Model of Earthquake-Induced Underground Engineering Slope Based on Gray Relation and Variation

Abstract:

Complicated and variational relation among the factors of the pregnant environment, resulted that, it was hard to orderly sentence the connection from the pregnant risk factors to the overall slope safety. Through differentiating risk relational factors into the extreme variation, same directional matrix was established for the pregnant environment safety of earthquake-induced underground engineering slope. Gray relation Analysis Model was established on the pregnant environment of earthquake-induced underground engineering slope, which was integrated with entropy information of same directional matrix. Model calculated out the gray relation degree and variation coefficient among the sample data sequence of the observed units, and finally sentenced the overall safety of underground engineering slope systemically. Example showed that toward the multi-objective decision-making problem for the safety assessment of underground engineering slope, model possessed with a scientific, simple, practical feature, whose outcome revealed the full status of the slope pregnant environment.
