雄安多要素城市地质标准体系研究

A study of the multi-factor urban geology standard system in Xiongan New Area

雄安新区作为多要素城市地质调查试点城市,急需建立城市地质标准,为高水平现代化城市管理提供全方位技术支撑。从城市地质与现代城市行政管理有机融合的角度角度出发,通过分析我国城市地质标准现状和雄安新区规划建设需求,研究提出雄安多要素城市地质标准体系。研究表明:高起点规划、高标准建设雄安新区,需要建立一套系统的、完整的、先进的多要素城市地质标准体系;标准体系应该包括空间、资源、环境和灾害等子体系:空间涵盖全域、重点区、特色小镇、工程建设场地等四方面,资源涵盖地热、矿泉水、地下水等三方面,环境涵盖土壤质量、地下水质量、湿地质量等三方面,灾害涵盖地面沉降、地裂缝、地震、砂土液化、地面塌陷等五方面。与雄安新区规划、建设、运行等不同阶段城市管理密切结合,需要研制30项城市地质技术标准,包括空间标准6项、资源标准9项、环境标准7项、灾害标准8项。

As a pilot city of multi-factor urban geological survey,Xiongan New Area urgently needs to establish the urban geological standards to provide comprehensive technical support for high-level modern urban management.From the perspective of the close integration of urban geology and modern urban administration,the multi-factor urban geological standard system of Xiongan is examined in this paper,based on the analyses of the current status of urban geological standards in China and the planning and construction requirements in the Xiongan New Area.The results show that the Xiongan New Area with a high starting point planning and high standard construction requires establishing a systematic,complete and advanced multi-factor urban geological standard system.The standard system should include four sub-systems including space,resources,environment and disasters.The space sub-system contains the whole area,the key areas,the characteristic towns and the engineering construction sites.The resources sub-system contains the quantity of geothermal resources,mineral water and groundwater.The environment sub-system includes the quality of soil mass,groundwater and wetland.The disaster sub-system includes land subsidence,ground cracks,earthquakes,liquefaction of sand and soil,and ground collapse.Closely integrated with the urban management at different stages of planning,construction and operation of the Xiongan New Area,it is necessary to develop 30 urban geological and technical standards,including 6 space standards,9 resource standards,7 environment standards and 8 disaster standards.
