摘要: 城市地质环境条件直接控制地下空间开发利用的难易程度,决定了地下工程的整体安全性和经济性,是地下空间开发利用评价的核心要素。武汉市地下空间开发利用受区域内地形地貌、岩土体条件、水文地质、地质结构与地震效应、不良地质与地质灾害等众多因素的影响。在收集武汉市主城区大量钻孔数据以及其它工程地质资料的基础上,建立了地下空间利用地质环境适宜性评价指标体系。基于评价标度以及群体判断矩阵的优化,建立了改进的地下空间开发利用适宜性评价模型,并结合MAPGIS平台进行二次开发对武汉市主城区浅层(0~15 m)地下空间开发利用地质环境适宜性展开综合评价。评价结果表明:评价区域内地下空间开发利用适宜性整体较好,适宜性差区域主要集中于汉口、武昌以及青山区靠近长江、汉江两岸的冲积平原等地,其评价结果亦可为武汉市主城区地下空间开发利用的整体规划提供指导与借鉴。

Abstract: Urban geological environment is a core factor in evaluating underground space utilization as it directly affects the utilization difficulty and determines the overall safety and economy of underground project. The underground space utilization in Wuhan city is affected by many factors inclusive of landform, rock and soil condition, hydrology, geological structure and seismic effect, as well as adverse geology and geological disasters. In this article, the suitability of geological environment in the utilization of shallow (0-15m) underground space in the main urban area of Wuhan city is evaluated. An index system is constructed according to a large number of drilling data and other engineering geological data. On this basis, an improved model for suitability evaluation is built based on optimizing evaluation scales and group judgment matrix, and then the evaluation result is obtained through secondary development with MAPGIS platform. Results show that the geological environment in the study area has overall a good suitability for underground space utilization, and poor suitability regions are mainly concentrated in Hankou, Wuchang, and Qingshan closed to the alluvial plains of the Changjiang River and the Hanjiang River. The evaluation results could also offer guidance and reference to the overall planning of underground space utilization of Wuhan.

Key words: main urban area of Wuhan, underground space, utilization and development, geological environment, suitability evaluation, improved analytic hierarchy process
