为合理确定矿山采石场边坡生态修复设计参数,基于多目标决策的理念,首次提出一套适用于矿山采石场边坡生态修复设计参数优化的技术方案,并以广西某废弃石灰岩矿山采石场高陡岩质边坡生态修复治理工程设计为例开展实例研究,提出以削坡坡度、坡高和平台宽度为决策变量,建立地质安全性-生态修复效益-工程总成本多目标决策模型,利用灰色关联分析评价模型对方案进行选优,得到该边坡生态修复治理工程的最优削坡设计参数组合.结果表明:本边坡削坡设计参数的最优组合是坡度为75°、坡高为6m、平台宽度为3.5 m.研究结果可为类似边坡工程的生态修复设计优化提供重要参考,具有一定的实际应用价值.
Optimization of ecological restoration design parameters of mine quarry slope based on multi-objective decision-making
To reasonably determine the design parameters for ecological restoration of mine quarry slope,based on the concept of multi-objective decision-making,this paper proposes a set of technical schemes for optimizing the design parameters of ecological restoration of high and steep rock slopes in mine quarries for the first time.Taking the ecological restoration and treatment engineering design of high steep rock slope in an abandoned limestone quarry in Guangxi as an example,this study carried out a case study and propo-ses a multi-objective decision-making model with geological safety,ecological restoration benefit,and pro-ject cost with slope,slope height,and slope platform width as parameters.The gray relational analysis eval-uation model was used to assess and optimize the proposed schemes,leading to the identification of the opti-mal design parameter combination of the slope ecological restoration and treatment project.The results in-dicate that the optimal combination of slope cutting design parameters is a 75° slope,6 m slope height,and 3.5 m platform width.The multi-objective decision-making scheme and model suggested in this paper can provide essential references for the ecological restoration design optimization of similar projects and have a good practical application value.
