雄安新区地下空间资源开发利用地质适宜性评价

    Evaluation on geological suitability of development and utilization of underground space resources in Xiong’an New Area

    • 摘要: 雄安新区开发作为千年大计、国家大事,地下空间资源的开发利用可促进新区高质量建设与可持续发展。通过层次分析法,建立了雄安新区地下空间资源开发利用地质适宜性评价指标体系,对雄安新区浅层、次深层、深层地下空间地质适宜性进行了评价。研究结果表明,雄安新区地下空间资源开发利用的地质适宜性评价指标可划分为五大类10个指标,主要影响指标为含水砂层、地面沉降、液化砂土、水土腐蚀性等;按浅层、次深层和深层将评价结果划分为适宜区、一般区和敏感区,其中适宜区和一般区总面积约占新区面积的 80%,说明雄安新区地下空间资源开发利用地质适宜性整体较好。该评价结果为雄安新区高质量建设及可持续发展提供了可靠的技术支撑。

       

      Abstract: Xiong’an New Area development is a grand project and a national event. The development and utilization of underground space resources can promote high-quality construction and sustainable development of the New Area. This paper establishes the evaluation index system of geological environment suitability for the development and utilization of underground space resources through the analytic hierarchy process and evaluates the geological environment suitability of underground space resources at different depths. The results show that the evaluation indexes can be divided into five categories and 11 indexes for the development and utilization of underground space in Xiong’an New Area. The main influence indexes are water-bearing sand layer, land subsidence, liquefied sand and corrosion of soil and water, etc. According to shallow, sub-deep and deep underground space, the suitability evaluation results were divided into suitable areas, less suitable areas and sensitive areas. The total area of suitable areas and less suitable areas accounted for about 80% of the New Area, indicating that the overall geological suitability of underground space development and utilization is good in Xiong’an New Area. The evaluation results provide reliable technical support for the high-quality construction and sustainable development in Xiong’an New Area.
