摘　　要：惠州市金山新城规划区被定位为惠州未来的城市中心。金山新城规划区第四系粗砂层及砾砂层富水性较好,单孔涌水量1166.82~6437.37 m^(3)·d^(-1),渗透系数为21.45~85.46 m·d^(-1)。岩土体按成因、结构、物质组成可分为侵入岩岩性组、喷出岩岩性组、碎屑岩岩性组、红层碎屑岩岩性组、碳酸盐岩岩性组和土体六大类。土地利用类型以农用地为主,占比52.56%,土壤质量以三等(中等)为主,占比54.07%。区内地下水资源较为丰富,地下水天然资源量为89072.57 m^(3)·d^(-1),允许开采资源量为86671.61 m^(3)·d^(-1)。目前地下空间开发利用主要集中在15 m以浅,其中地下商业设施与地下车库已利用的地下空间约9000万m^(3)。区内地质环境问题主要有断裂活动性、地质灾害、隐伏岩溶、软土和水土污染。工程建设适宜区主要分布于中部及北部地段,面积54.46 km^(2),占比46.04%,区内大部分区域地下空间结构有利于开发利用。重大工程建设时应注意避让活动断裂、隐伏岩溶区与深厚软土区,并关注工程建设可能引发的地面沉降问题。重视地下空间资源的开发利用,加强应急备用地下水源地保护。建设城市地质信息综合服务系统,加强海绵城市建设和湿地保护,进一步加强地质灾害防治工作。Jinshan New Town planning area is located as the future urban center of Huizhou City.With the rapid development of the area,the geological resource status and geological environmental conditions have also changed greatly,so it is necessary to carry out urban geological survey to facilitate urban planning and construction and sustainable development.By summarizing the main results of urban geological survey in Jinshan New Town planning area,countermeasures and suggestions are put forward to promote the scientific development of the city.The results show that the Quaternary formation in Jinshan New Town planning area is good in water enrichment,with single hole inrush water of coarse sand and gravel sand layers ranging from 1166.82~6437.37 m^(3)·d^(-1),and permeability coefficient ranging from 21.45~85.46 m·d^(-1).According to the cause of formation,structure and material composition,the rock and soil can be divided into six categories:intrusive rock lithology group,extrusive rock lithology group,clastic rock lithology group,red layer clastic rock lithology group,carbonate rock lithology group and soil.The land use type of Jinshan New Town planning area is mainly agricultural land,accounting for 52.56%,and the soil quality is mainly grade three(medium),accounting for 54.07%.The groundwater resources in the area are relatively rich,with the natural groundwater resources of 89072.57 m^(3)·d^(-1),and the permitted exploitation resources of 86671.61 m^(3)·d^(-1).At present,the development and utilization of underground space are mainly concentrated in the shallow 15 m,among which the underground commercial facilities and underground garage have used about 90 million m^(3)of underground space.The geological environmental problems in the area mainly include faults,geological disasters,karst,soft soil and soil and water pollution.The suitable areas for engineering construction are mainly distributed in the central and northern areas,covering 54.46 km^(2),accounting for 46.04%,and the underground spatial structure of m
