广东省五山台倾斜仪设置在地表下40米左右的窿道内,几年来观测资料表明,它不仅受到气温、气压的影响,而且还与降雨有一定的密切关系。这固然与广东地处南方,雨季长、雨量多有关,但该窿道本身穿过风化花岗岩破碎带也是一个重要原因。根据日本对山崎断层的研究,对地形变的连续观测,下雨的影响是造成很大干扰的原因,而受下雨影响所产生的剧烈变动又集中在破碎带上,破碎带的存在使降雨在很大程度上支配着局部地区的应力场变化。
The Wushantai Inclinometer in Guangdong Province is set in a tunnel about 40 meters below the ground surface. Observational data over the past few years show that it is not only affected by temperature and pressure, but also has a certain close relationship with rainfall. Although this is related to the fact that Guangdong is located in the south with long rainy seasons and rainfall, it is also an important reason that the runway itself passes through the weathered granite crushing zone. According to the study of the Yamasaki fault in Japan, the continuous observation of the deformation of the terrain and the influence of the rain are the causes of great disturbance. However, the violent changes caused by the rain are concentrated in the crushed belt. The presence of the broken belt makes the rainfall To a large extent, dominate the changes in the stress field in some areas.
