高速铁路建设对宝鸡地电场观测干扰分析

摘要

High-speed railway construction is a major strategic measure to achieve sound and rapid economic development in the new era. A high-speed railway network as long as 16 000 km will be constructed all over China in the coming future. Geo-electric field observation is an important way for earthquake precursory observation and 110 geo-electric field stations have been in operation since 2010. It is inevitable for the high-speed railway lines to interfere with geo-electric field observation. Therefore, studying and analyzing the influence on the geo-electric field observation by the high-speed railway design is a new issue, which has practical signifi- cance for applying the observation data, exploring the anti-interference method and selecting the site of new stations. The interference with the observation in Baoji geo-electric field by the high-speed railway construction is analyzed and the conclusion is given out in the paper.%高速铁路（简称高铁）建设是新时期中国经济实现又好又快发展的重大战略举措。不久的将来,我国将建成遍布大江南北总进程达到16 000 km的高铁网络。地电场观测是地震前兆观测的重要手段,截止2010年,全国共建成并投入运行的地电场观测台站已经达到110个。由于高铁的设计线路与地电场观测场地难免发生＂冲突＂,因此,研究和分析高铁建设对地电场观测的影响是一个新的重要课题,对观测资料的运用、抗干扰方法的探索、新建台站的选址都有借鉴意义。针对宝鸡地电场测区内高铁建设对观测的干扰进行分析,并得出相关结论。
