摘要
隧道建设会造成相应的环境地质问题,如地下水漏失引发的地面沉降、地下水水质恶化、地表植被生态破坏等。通过文献调研并结合工程实例提出隧道疏排地下水对植被生态影响的风险评价指标,并对指标进行量化分级;利用层次分析法求得各指标权重;利用云模型理论构建各指标在不同评价等级上的云模型。该评价体系能够比较真实地反映隧道地下水疏排与隧顶植被的关系,对评价目标工程建设对植被生态的影响有一定的指导作用。
The construction of tunnel will create corresponding environmental geological problems,such as ground subsidence,groundwater quality deterioration,surface ecological vegetation destruction caused by groundwater leakage and so on.The risk assessment index of tunnel drainage groundwater on ecological vegetation was put forward based on literature research and engineering examples,and the index was quantified and classified.The analytic hierarchy process(AHP)was used to obtain the weight of each index by using the cloud model theory to construct the cloud model with different evaluation levels of each index.The evaluation system can reflect the relationship between drainage of groundwater and vegetation on the roof of tunnel,and has a certain guiding role for the impact of the evaluation target project construction on vegetation ecology.
