河西走廊荒漠地貌及地貌条件的公路工程评价

Study on Desert Geomorphic of Hexi Corridor and Estimation to Geomorphic Highway Engineering

依据河西走廊荒漠地貌成因和地表组成物质的不同,划分出岩漠、砾漠、沙漠、泥漠等类型,讨论其主要特征,并指出其受走廊盆地控制而呈现不规则的同心带状分布规律;对上述地貌条件进行了公路工程评价并提出相应的防范改造工程技术措施.

The reason of forming the desert geomorphology and different components of the ground in Hexi corridor are discussed in this paper, which can be divided into four types:rocky desert, gravel desert, sand desert and mud desert based on the genesis, characteristics and debris formed the earth surface . The distributing law of the presented anomalistic concentric shape under the control of corridor basin is pointed out. According to the characteristics and distribution of these four types of desert, the estimation to highway engineering and preventive measure has been put forward. 
