摘要
以某地中心城区地层结构为研究对象,通过收集研究区内历史钻探资料,获取浅层、中层和深层的地层结构。根据各评价因子对浅层、中层和深层地下空间开发利用的影响程度,选取不同的评价因子作为评价指标,通过层次分析法确定各评价因子的权重,分别建立了研究区浅层、中层和深层地质环境适宜性评价体系。通过评价体系对研究区的地下空间地质环境适宜性进行了评价,结果表明,浅层地下空间地质环境一般适宜区和不适宜区占比27.8%,中层地下空间地质环境一般适宜区和不适宜区占比26.4%,深层地下空间地质环境一般适宜区占比16.2%;随着地下空间开发深度的增加,适宜区的面积不断增加。
The study focuses on the stratigraphic structure of the central urban area of a certain location.By collecting historical drilling data within the study area,the stratigraphic structures of shallow,middle,and deep layers were obtained.Based on the influence of various evaluation factors on the development and utilization of shallow,middle,and deep underground spaces,different evaluation factors were selected as evaluation indicators.The weights of these evaluation factors were determined using the Analytic Hierarchy Process(AHP),and suitability evaluation systems for the geological environment of shallow,middle,and deep layers in the study area were established accordingly.The geological environment suitability of the underground space in the study area was evaluated using these systems.The results indicate that:the proportion of generally suitable and unsuitable areas for shallow underground space is 27.8%,the proportion of generally suitable and unsuitable areas for middle underground space is 26.4%,the proportion of generally suitable areas for deep underground space is 16.2%;as the depth of underground space development increases,the area of suitable zones continuously increases.
