Thomas Geschwindefraction surveys have been carried out as a preliminary study to obtain dynamic characteristics. The site surface geology consists of young sediment of conglomerate in Pleistocene period above granite rock. A velocity sensor with a natural period of 0.5 s was used to monitor the micro-tremors at sev恶臭 发表于 2025-3-25 07:59:50
