摘要
填土高边坡作为一种特殊类型的土质边坡,其力学参数的离散度与施工密切相关。找出各参数对边坡稳定性的依次影响程度,以及在超载和地震作用下它们对稳定性的影响程度所发生的变化,对此类边坡设计和施工控制起着重要的作用。本文以湖北大畈某填土高边坡为依托,采用正交设计法分析了各力学参数对边坡稳定性的影响程度以及超载和地震对稳定因素产生的影响,可为此类边坡的进一步研究提供参考。
The filled high slope is a peculiar type of soil slope,and the dispersion of its mechanical parameters is closely related to the construction process.Thereby in order to have a better control over design and construction for this type of filled slope,it is very important to find out the ordinal significance of all parameters on the stability of the slope and what will happen under the condition of earthquake or overloading.Taking the filled high slope of Dafan（in Hubei province）as an example and on the basis of changing law of the stability factor due to the earthquake and overloading distance away from the slope top,this paper presents some analytic results in those aspects with the method of orthogonal design,which will be valuable for future research.
