基于组合权重的文一路地下空间开发适宜性评价

对地下空间开发适宜性进行科学、合理的评价,是避免地下空间资源浪费,保证其健康可持续发展的前提。基于地形地貌、工程地质、水文地质、不良地质作用和建设现状构建地下空间开发适宜性评价指标体系,通过数值模拟确定盾构隧道施工的影响范围,完成建设现状评价指标分级量化；分别采用层次分析法和熵权法计算评价指标主观和客观权重,通过博弈论确定组合权重。在此基础上,利用综合指数法对杭州市文一路地下空间开发适宜性进行评价。通过评价结果对比分析和学院路地下工程实例,验证了评价模型的可靠性,为地下空间开发规划提供指导和借鉴。

Suitability Evaluation of Wenyi Road Underground Space Development Based on Combination Weight

The suitability of underground space development is scientifically and reasonably evaluated, which is a prerequisite for avoiding wastage of underground resources and ensuring their healthy and sustainable development. Based on topography and geomorphology, engineering geology, hydrogeology, adverse geological effects and construction status, the suitability evaluation index system of underground space development was constructed, and the influence scope of shield tunnel construction was determined through numerical simulation, and the evaluation index of construction status was quantified. The analytic hierarchy method and the entropy weight method were used to calculate the subjective and objective weight of the evaluation index, and the combination weight was determined by game theory. On this basis, the comprehensive index method is used to evaluate the suitability of the underground space development of Wenyi Road in Hangzhou. Through the comparative analysis of the evaluation results and the examples of underground engineering of College Road, the reliability of the evaluation model is verified, and the guidance and reference are provided for the development planning of underground space.
