Abstract：There are several bad geological phenomena, such as:the mined—out areas, the storm of sand along the valley of Dayanghe River in west segment of Datong—Qiahuangdao t and the Beijing—Baotou Railway Line passes there situated on Yanshan Mountain subsidence belt. The Sangganhe River gorge with high mnimtains and rl.^ep valleys is v^ry complicated in geological structure. Varied harmful geological phenomena are widespread whether a bet?ter alignment could be chosen was the key that decided the west segment could be straight.
