摘要
西藏中波水电站库区长约26.2km,两岸不连续分布高陡基岩边坡、冰水堆积物、泥石流堆积物、崩坡积物等,在稳定性定性评判的基础上,将层次分析法和模糊数学理论相结合,建立库岸稳定性多层次模糊半定量评价模型,该模型考虑各类稳定性影响因子,在确定各因素权重和评价矩阵的基础上,得到岸坡稳定性评价的定量结果。通过与定性评价结果相比较,吻合性较好,对实际工程具有一定指导价值。
The length of reservoir area in Tibet medium wave hydropower is about 26.2 km,and reservoir area is distributed high and cliffy slope with bedrock,ice water deposits,debris flow deposits,collapse slope sediments and so on.On the basis of stability evaluation,we combine analytic hierarchy process with theory of fuzzy mathematics,and establish the model of stability of reservoir with multi-level and fuzzy half of the quantitative evaluation,stability in shore.We have considered various kinds of impact factors in this model.On the basis of determining all kinds of weight factors and evaluation matrix,we get the result of quantitative evaluation to stability of reservoir.Compared the result with the qualitative evaluation,the coincidence is well,which has a certain advice to actual project.
