A study of the multi-factor urban geology standard system in Xiongan New Area[J]. Hydrogeology & Engineering Geology, 2021, 48(2): 152-156. doi: 10.16030/j.cnki.issn.1000-3665.202008076 |
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.
