包头市场地稳定性与地下空间资源开发利用适宜性评价OA
Evaluation of site stability and suitability for underground space development and utilization in Baotou city
基于呼包鄂城市综合地质调查项目成果,系统开展了包头市场地稳定性与地下空间适宜性评价.研究表明:包头市场地稳定性呈现"北稳南欠,断裂控局"的宏观格局,活动断裂带与黄河沿岸液化区是主要不良地质作用.针对 0～80 m 深度范围,构建了分层评价指标体系,结果显示:浅层(0～10 m)和次浅层(10～30 m)地下空间次适宜以上级别占比均超 81%,主要制约因素为砂土液化;次深层(30～50 m)和深层(50～80 m)适宜性更优,次适宜以上级别占比分别达 92.07%和 98.53%,开发核心问题转为承压水头与地基承载力.评价成果为包头市地下空间资源的安全与集约开发利用提供了科学依据.
Based on the results of Hohhot-Baotou-Ordos comprehensive urban geological survey project,a systematic evaluation of site stability and underground space suitability in Baotou city was conducted.Research shows that the site stability in Baotou exhibits a macro pattern of"stable in the north and poor in the south,controlled by faults薰 with active fault zones and liquefaction areas along the Yellow river being the main unfavorable geological processes.A hierarchical evaluation index system was established for depth range of 0～80 m.The evaluation results show that areas rated as moderately suitable or above both exceed 81%for the shallow(0～10 m)and sub-shallow(10～30 m)underground spaces,with sand liquefaction being the primary constraint.The suitability of sub-deep(30～50 m)and deep(50～80 m)layers is even better,with the proportion of areas rated as moderately suitable or above reaching 92.07%and 98.53%respectively,and the core development issues shift to confined water head and foundation soil bearing capacity.The evaluation results provide a scientific basis for safe and intensive development and utilization of underground space resources in Baotou city.
