Xuzhou East Station, located in Xuzhou City, Jiangsu Province, China, is affiliated to China Railway Shanghai Bureau Group Co., Ltd. It is one of the seven hub stations of Beijing-Shanghai high-speed railway, the starting station of Xu Lan high-speed railway, Xu Lian high-speed railway and Xu Yan high-speed railway, and an important part of Xuzhou railway hub.
Xuzhou geological structure
Xuzhou belongs to the south of North China fault block area in geotectonics. Its geological conditions and structure are not too complicated, and the frequency and intensity of seismic activity are low. ?
Judging from the crustal structure, the crustal thickness of Xuzhou has not changed much. The average depth of Mohs surface is about 36 kilometers, and the average depth of Kangmian surface is 20 kilometers, which is generally deep in the west. Look at tectonic movement again. Xuzhou belongs to a large-scale subsidence area in Subei Plain. The landform is low and flat, and the sediments in the fault basin are thick, showing the characteristics of * * * oscillation movement.
Judging from the fault structure, the faults in Xuzhou area are relatively developed. According to its scale and its role in the history of geological development, the most important faults in the north and east are widely distributed. The main fault zones in Xuzhou are: Tancheng-Lujiang fault zone, Fengxian-Pizhou fault zone, so the Yellow River fault zone.
The terrain of Xuzhou is mainly plain, which accounts for about 90% of the city's area. The overall topography of the plain decreases from northwest to southeast, with an average slope of 1/7000- 1/8000, and an altitude of 30-50 meters.
