引洮的总干渠由甘肃省岷县古城經月亮山到庆阳董志源,全長1400余公里。西部是祁連山,北面是黄土高原,南面是西秦嶺的北侧,东穿六盤山。从工程地質观点来看,研究本区的新構造运动对此項共产主义的水利工程有重要的实际意义。根据新構造现象,可推測基岩的稳固性。同时在新構造存在的地 Guanyin the main trunk from the ancient city of Minxian in Gansu Province by the Moon Hill to Qingyang Dong Zhiyuan, a total length of 1,400 kilometers. The west is the Qilian Mountains, the north is the Loess Plateau, the south is the north side of the West Qinling, wearing Liupanshan in the east. From the perspective of engineering geology, studying the neotectonic movement in this area is of great practical significance to this communist water conservancy project. According to the new tectonic phenomena, we can speculate the stability of bedrock. At the same time in the new structure exists
