Characteristics of the In Situ Stress Field and Engineering Effect along the Lijiang to Shangri-La Railway on the Southeastern Tibetan Plateau, China

Table 2

The main characteristics of active faults along the Lijiang to Shangri-La railway from south to north.

No.	Fault name	Length	Attitude of fault			Fracture property	Epoch of latest activity	Seismic activity
			Strike	Dip	Dip angle
12	Xiaojin river-Lijiang fault	70 km	NE	NW	60°–80°	Left-reverse	N–Q1	M 6.1 in 1951
								M 6 in 1996
24	Lijiang-Dajun fault zone	55 km	Close to SN	E/W	60°–80°	Left-normal	Q3-Q4	M 7.0 in 1996
23	Longpan-Qiaohou fault	110 km	NNW-NNE	W	60°–80°	Right-reverse	Q3-Q4	M 6() in 1688, M 6() in 1751
								M 6 in 1961
23	Zhongdian fault	60 km	NW	NE	70°	Right-lateral strike-slip	Q3-Q4	M 6() in 1933

The fault number is shown in Figure 1(c). N: Neogene; Q₁: Lower Pleistoncene; Q₂: Middle Pleistoncene; Q₃: Upper Pleistoncene; Q₄: Holocene.
