摘要
西咸新区作为国家"一带一路"、"西咸一体化"等重大经济规划的重要组成部分,在周边地区发育多条活动性断裂,其对百姓日常生活影响较大。西咸新区城镇化建设迫切需要城市地质工作为其提供一定的科研成果作为参考和指导。为了更好的探明西咸新区断裂情况,拟以土壤氡气测量为主要探测手段,在研究区内布置15条测氡测线,结合地震剖面与露头剖面等其他相关资料来判断西咸新区内活动断裂分布情况。结果表明:1在西咸新区范围内,泾河断裂与渭河北岸断裂存在,其中泾河断裂分布于泾河河谷之下,渭河北岸断裂分布于渭河二级阶地与三级阶地之间。2西咸新区范围内渭河南岸断裂不存在,沣河断裂与皂河断裂则有待进一步研究。
Xi-Xian New Area is an important part of the economic development programs in Chinese government＇s plan,such as＂The Belt and Road＂and＂The integration of Xi-Xian＂.A number of active faultsare developed surrounding this area, which bring apparent impact on civilians＇daily life.The urban geological work is urgently needed to carry out,which can provide a certain geological guidance for the planning and construction of Xi-Xian New Area.In order to find out the exact distribution of these active faults,15 radon monitor sections have been set out,and the distribution of active faults in Xi-Xian New Area has been analyzed and discussed through taking the soil radon monitor as the main detection method,and combining with the seismic sections,geological outcrop sections and other geological data.The results show that the Jing River Fault and the northern Wei River Fault are existed in this area.In which,the Jing River Fault is located under the Jing River Valley,while the northern Wei River Fault is situated at the area between the second and third terraces of Wei River.The Southern Wei River Fault and the Zao River fault are not existed in this area,and the details about these faults need to be further studied.
