摘　　要：为了支撑服务雄安新区的总体规划,本文通过对比分析前期勘察的雄安新区496个钻孔岩芯资料及19449组岩土体物理力学试验资料,明确了雄安新区城市地下空间开发利用层的物质载体及其空间组合关系,建立了雄安新区地下空间开发利用层0~100m的工程地质结构并划分了18个标准工程地质层组;分析了不同工程地质层组岩土体的物理力学特性,并对其工程地质特性进行了评价;探讨了地下空间开发利用过程中可能存在的工程环境地质问题及产生的环境地质效应,指出了地下工程建设过程中需要重点防范的工程地质问题和合理利用地下空间资源的方法,为雄安新区的总体规划建设提供了可靠的参考依据。In order to service the overall planning of Xiongan New Area,after comparing the core data of 496 boreholes and totally 19449 groups of physical and mechanical test results of rock and soil sample in Xiongan New Area,the strata and spatial structure with the underground space development zone in the area is identified;the engineering geological structure system is established and is classified into 18 nos.of standard engineering geological layers within 100m in depth;the physical and mechanical properties of each geological formation are analyzed and evaluated;the engineering geology problems and the environmental geology effect brought during the development and utilization of the underground space are discussed;the key engineering geology problems that need to be paid attention during the construction of underground engineering and the rational utilization of underground space resources are pointed out.The study would provide a reliable basis for the planning and construction of Xiongan New Area.
