“十一五”期间,在国家863重大计划项目支持下,开展了我国航空地球物理野外试验场建设.在总结国内外航空地球物理试验场建设情况基础上.以加拿大Reid-Mahaffy航空电磁地球物理场为例,从试验场场址选择和试验场建设两方面,分析了国外航空地球物理试验场建设方法,总结了相关经验和借鉴意义.在此基础上.根据我国航空地球物理试验场建设目标,综合考虑不同航空地球物理测量系统的特点,制定了我国航空地球物理试验场建设的基本条件.根据这些条件,采用“先选区后选场,区中选场”的原则,进行了试验场场址的选择,最终确定大井坡航空地球物理试验场为我国首个航空重、磁、电磁等测量系统的野外综合检测平台(简称为大井坡试验场).根据试验场建设思路,在分析大井坡试验场现有条件基础上,从岩石物性测量与研究、地球物理测量、地质填图与剖面测制以及试验场数据信息管理等方面提出了试验场的建设内容与方法.
During the “Eleventh Five-Year Plan” period, under the support of the National 863 Major Project, the construction of China’s aviation geophysical field test site was carried out. On the basis of summarizing the construction of the aviation geophysical test site both at home and abroad, Canadian Reid-Mahaffy Aeronautical Electromagnetic Geophysical field as an example, this paper analyzes the construction methods of foreign aeronautical geophysical test sites and summarizes the relevant experiences and reference significance from two aspects: the site selection of the test site and the construction of the test site.On this basis, according to China’s aviation geophysical test site According to these conditions, the principle of “pre-selection area after the election field, the district in the election field ” principle was carried out, and according to the characteristics of different aviation geophysical measurement system, The selection of the site of the test site and the final determination of the Dajingpo Aeronautical Geophysical Testing Station are the first comprehensive field test platform for the measurement of heavy, magnetic and electromagnetic systems in China (referred to as the Dajingpao test site for short). According to the construction of the test site, Based on the analysis of the present conditions of Dajingpo Experimental Site, from the aspects of petrophysical properties measurement and research, geophysical survey, geological mapping and profile measurement Proving Ground data and information management proposed the construction of contents and methods of testing ground.
