武汉市主城区次浅层地下空间利用适宜性评价
Suitability evaluation of sub shallow underground space utilization in main urban areas of Wuhan
摘要
Abstract
With the construction of subway and large underground complex in the main urban areas of Wuhan,the development and utilization of sub shallow(10-30 m)underground space has become the focus of impro-ving the comprehensive bearing capacity of the main urban area based on a large number of drilling data.The suitability evaluation index system for the development and utilization of sub shallow underground space in the main urban areas of Wuhan is constructed from four aspects of rock and soil conditions,hydrogeology,geolog-ical structure and seismic effects and adverse geological disasters.In order to determine the weight values of each evaluation indicator,AHP is improved by exponential scaling and optimal judgment matrix methods.The suitability evaluation results for the main urban areas of Wuhan is calculated by fuzzy comprehensive evaluation method with the assistance of secondary development on the MapGIS platform.The suitability evaluation results of sub shallow underground space in the main urban areas are obtained by fuzzy comprehensive evaluation meth-od.The results show that the proportion of areas with excellent,good,medium and poor suitability is 7.14%,55.62%,26.69%and 10.55%,respectively.The evaluation results can provide reference for the early plan-ning of underground space development and utilization.关键词
