    Evaluation method of landslide stability by using improved fuzzy mathematical based on entropy weight method

    • 摘要: 滑坡是中国最为常见的一种地质灾害类型,其具有的易发、频发特点使得人民的生命财产安全受到了严重的威胁,滑坡的稳定性评价是滑坡防灾减灾工作中最为关键的一项工作。鉴于滑坡诱发因素具有模糊性的特点,文章以勉县新铺镇发育的典型堆积层滑坡为例,在地质环境条件分析的基础上,考虑了采用模糊数学法进行滑坡稳定性评价,并引入热力学中“熵”的概念,采用熵权法确定了滑坡诱发因子的权重,进而提出了一种基于熵权法改进的模糊数学滑坡稳定性评价新方法。结果表明:新提出的基于熵权法改进的模糊数学滑坡稳定性评价方法克服了传统模糊综合评价方法主观性判断滑坡影响因子权重的弊端;通过数值模拟法进行滑坡稳定性定量化分析验证,发现两种方法评价结论较为吻合,说明了所提出的新方法具有一定的可靠性。基于熵权法改进的模糊数学滑坡稳定性评价方法较为快速简捷,可用于临灾快速预警、应急救援等突发情况下的滑坡防灾减灾工作。

       

      Abstract: Landslide is the most common type of geological disaster in China, with its easy and frequent occurrence characteristics, posing a serious threat to the safety of people’s lives and property. The stability evaluation of landslides is the most crucial task in landslide disaster prevention and reduction work. Due to the fuzziness of landslide inducing factors, a certain accumulation layer landslide in Xinpu Town, Mianxian County is taken as an example in this article. Based on the analysis of geological environmental conditions, fuzzy mathematics method is considered for landslide stability evaluation, and the concept of "entropy" in thermodynamics is introduced, the entropy weight method is used to determine the weight of landslide inducing factors, and a new fuzzy mathematics landslide stability evaluation method improved on the entropy weight method is proposed, The results show that the newly proposed fuzzy mathematical landslide stability evaluation method based on the entropy weight method overcomes the drawbacks of the traditional fuzzy comprehensive evaluation method of subjectively judging the weight of landslide impact factors. The quantitative analysis and verification of landslide stability by numerical simulation method found that the evaluation conclusions of the two methods were in good agreement, indicating that the proposed new method has a certain degree of reliability. The improved fuzzy mathematics landslide stability evaluation method based on entropy weight method is more fast, and simple. It is very suitable for landslide disaster prevention and reduction work in emergency situations such as rapid warning of impending disasters and emergency rescue.
