【摘要】 为了给城市工程建设规划提供基础地质资料,需查明区内断裂的准确位置、产状以及覆盖层厚度。利用CSAMT方法进行了勘察工作,为避免区内人文干扰和电磁的严重干扰,野外施工时采用了多种手段以保证观测数据的可信度;数据处理时首先利用五点平滑进行去噪处理,然后利用空间滤波消除静态效应,最后采用基于遗传算法的CSAMT全资料反演程序对野外数据进行反演。分析反演结果并结合已知地质资料,给出了区内断裂的准确位置等信息。更多还原

【Abstract】 In order to provide basic geological information for a city construction plan,it is necessary to identify the precise location of the faults,the thickness of the overburden,and estimate the activity of the faults.We used CSAMT method for survey work.As there was strong electromagnetic interference in the survey area,we took many means to ensure the data obtained credible.By employing genetic algorithms full data inversion program for data inverse,we achieved a good result.With comprehensive analysis of the geophysics and geological data,we have determined the precise locations of faults.更多还原
