Analysis and application of detection ability in microtremor observation
摘要
Abstract
Based on the application results of microtremor technology in recent years,this paper proposes two indicators that can be used to evaluate the detection ability of microtremor observation:detection depth and longitudinal resolution.A-mong them,the main factors affecting the detection depth of the observation are the side length of the observation and the dom-inant frequency of the geophone;The main factors affecting the longitudinal resolution of the observation observation are obser-vation form and sampling interval.Based on comparative tests,the technical route of microtremor technology to achieve large detection depth in a thick coverage area is established,and it is verified in the west section of the petrochemical fault of Urumqi Bagang-Shihua.The detection results are consistent with the known data,which proves that the test conclusion is effective and reliable.关键词
