工程地质条件对武汉市地下空间开发利用的影响

Study on Influence of Engineering Geological Conditions on Underground Space Development in Wuhan City

根据武汉市地下空间开发的规划,在工程地质调查的基础上,将武汉市主城区浅层和次浅层地下空间的工程地质条件作为研究对象。在对诸多工程地质条件进行分析后,运用AHP(Analytic Hierarchy Process)层次分析法,将影响武汉市地下空间开发的各种工程地质因素进行了归类,并对各影响因素进行了分级,建立影响因素的评价体系和评价方法。对相关构造矩阵建立,并进行了一致性检验,确定了各指标的权重后,与工程实际进行了比对分析,提供了影响性评价的算法和数据来源。将主城区分隔成方块后,分别对每个方块进了影响性评价,并形成了影响性分区,形成了微影响区、较影响区和极影响区。在分区评价的基础上,提出了各区域的施工建议及相关注意事项。

According to the development planning of underground space in Wuhan city,based on the geological survey,the shallow underground space in main urban area is considered as the research object.After analysis on the geological condition factors affecting the development of underground engineering,the AHP（Analytic Hierarchy Process） method was applied to classify the influencing factors and establish for them the evaluation system and approach.After setting up the structural matrixes,their consistency test was qualified,the weight of each index,consistent with the engineering practice,was determined,and the algorithm of the evaluation and the data sources were provided.After the main urban area was divided into blocks and evaluation to each block,the slight influenced zone,the more influenced zone and the extreme influenced zone were shaped.Moreover,relevant construction suggestions and considerations to all zones were provided.
