软硬岩互层边坡治理优化研究
摘要:针对软硬互层边坡治理方案优化中存在方案偏好与客观信息问题，基于余弦决策原理，建立了软硬互层边坡治理方案优化余弦决策方法。该方法首先将评价指标划分5级，指标权重依据其级别来确定。然后根据余弦公式，计算待评价方案指标线段与理想方案指标线段之间夹角余弦值，建立软硬互层边坡治理方案优化模型。并将所建优化模型应用于彭家湾边坡治理方案优化，得到了最优治理方案，为其治理设计与施工决策提供依据。
Abstract:In view of optimization of treatment of slopes with interbreeding of soft and hard rocks,there are problems of scheme preference and objectiveinformation.And based on cosine decision principle,the cosine decision method has been established for optimization of slopes treatment scheme with interbreeding of soft and hard rocks.First of all,this method divides the evaluation index into 5 levels,and the weight of index is determined according to its level.And then according to the cosine formula,calculated the cosine of the angle between the index line of evaluation scheme and ideal target line segment,and building a model of optimization of treatment of slopes with interbreeding of soft and hard rocks.The model is applied to the optimization of Pengjiawan slope control scheme and the optimal treatment scheme is obtained,thus it provides the basis for its treactment design and construction decisions.
