面向盾构施工方法的地质环境质量三维综合评价方法研究

盾构法是一种广泛应用于地下工程建设的技术，但在施工中面临一系列的地质环境问题。现有的研究针对地下空间地质环境质量进行综合评价，存在着针对性不强、应用场景局限等问题。文章以杭州钱塘新区为研究对象，基于研究区三维地质模型，构建针对盾构施工方法的三维地质环境质量评价指标体系，采用多种空间分析方法进行评价因子提取，并利用离差最大化模型对多种综合评价结果进行组合，更好地兼顾主观和客观赋权评价模型的特点和优势。研究结果表明，该方法能够为地铁盾构施工提供更为准确的决策支持，更好地服务于城市地下空间工程建设。

The shield tunneling method is widely used in underground engineering construction, but it faces a series of geological environmental challenges during implementation. Although existing studies have conducted comprehensive evaluations of geological environmental quality in underground spaces, they often lack specificity and have limited applicability. Therefore, this paper takes Qiantang New Area in Hangzhou City as a case study. Based on a three-dimensional geological model of the study area, a three-dimensional geological environmental quality evaluation index system tailored to shield tunneling construction is established. Various spatial analysis methods are employed to extract evaluation factors, and a model maximizing deviation is utilized to integrate multiple comprehensive evaluation results, aiming to balance the strengths of subjective and objective weighting models. The results demonstrate that this method can provide more accurate decision support for metro shield tunneling construction, better serving urban underground space engineering projects.
