基于可拓理论的受纳场边坡稳定性评价研究
|
摘要
随着我国城市建设的快速发展,渣土受纳场日益增多,受纳场边坡灾害严重影响城市公共安全。以受纳场边坡为研究对象,通过总结受纳场边坡稳定性的主要影响因素,采用熵权法获取评价因素的权重系数,建立了一种基于可拓理论的受纳场边坡评价方法,并以深圳市某受纳场为例,验证评价方法的有效性。结果表明:该受纳场边坡等级变量特征值约为2.1,介于较稳定至基本稳定间,与实际监测结果对比,吻合较好,该方法为受纳场边坡评价工作提供一种有效、可靠的途径。
With the rapid development of urban construction in China,the number of waste landfill sites has gradually increased. The slope disasters of waste Landfill Sites affect seriously the public security of the city. The slope of waste landfill sites as the research object in this paper. The key factors affecting the slope stability of the waste landfill sites are summarized. The entropy weight method is used to obtain the index weight coefficient in the process of empowerment. This paper presents a method for evaluating the slope stability of the waste landfill sites based on extension theory. A slope of waste landfill site in Shenzhen as an example demonstrates the reliability of evaluation method. The results show that the slope comprehensive eigenvalue of waste landfill site is about 2. 1 which is between the stability grade two to three. The evaluation result is in accord well with the actual monitoring result of the slope,and the method for evaluation of the waste landfill site slope to provide an effective and reliable way.
