This research to be related to utilize shallow seismic reflection method that examine, in order to is it investigate Chi-Shan fault southwest section is it enter Kaohsiung Da-She , Ren-Wu , Da-Liao possible position of district to extend. Because in the past, to one section of states extended of southwest of Chi-Shan fault, because the shortage appears outcrop, so precise evidence has been enough to describe its position extended, and can only estimate and examine differentiating through the difference between rock and topography of the stratum. This research, according to possible trend of Chi-Shan fault of picture one of Kaohsiung (the 61st) of department central geological survey,MOEA, design 16 examining the line of about ten kilometers in total length, is distributed in Da-She , Ren-Wu , Da-Liao. Among them cooperating partly examine the selection of the line by adjusting the well drilling position of metropolis area of Kaohsiung, issue can make use of materials of rock make in the pit for to reflect signal characteristic than use to control, explanation that is constructed to the underground stratum with the profit. Synthesize 16 results of examining the line and find, the Chi-Shan fault inferred by Chinese Petroleum Corporation (CPC) was in the extension of the area of Kaohsiung in the past, or estimated and examined the Chi-Shan fault described to distribute by central geological survey,MOEA, reflection seismic the materials got with this research different to some extently
