Abstract:
Eastern Gansu Province, located in the center of Loess Plateau,is typical loess deposit area. There is rich oil and gas re- source under the area. Combing the project of Changqing oil field construction, the authors investigated topography, strata, and construction condition of the area, and divided the area into four engineering geological zones as Dongzhi platform zone(Ⅰ),Puru- malian zone(Ⅱ),Jingchuan-rouyuan zone(Ⅲ)and North Hedao river zone(Ⅳ). The Dongzhi platform zone(Ⅰ),located in the south of Hedao river and Yuele County,is a large loess platform with plat and wide landform. The zone is the main construction area.It has 250m depth of loess deposit with self-weight collapsibility loess. Collapsibility degree belongs toⅡ-Ⅲ grade. Puru- malian zone(Ⅱ)is the second terrace of river in Longdong area with limited space to construction. The loess deposit in this zone is Q3with non-self-weight collapsibility. Collapsibility degree isⅡ grade. Jingchuan-rouyuan zone(Ⅲ)is the first terrace of river with limited space to construction. The loess deposit is Q4with non-self-weight collapsibility, Collapsibility degree isⅠ-Ⅱ grade. North Hedao river zone(Ⅳ)is a large area with loess ridge and hill in north of Hedao river and Yuele County. This area is not suit- able to construct mostly.
