摘要:
陇东位于黄土高原腹地,是典型的黄土地层发育区,地下有丰富的石油天然气资源。结合长庆 油田建设项目,根据该区地形地貌及其黄土主要工程地质特征,将该地区分为董志塬区Ⅰ)、蒲茹马莲 区Ⅱ)、泾川环柔区Ⅲ)和合道川北区Ⅳ)4个工程地质区。董志塬区Ⅰ)主要包括合道川、悦乐以南 的广大黄土塬地区,由13个小的黄土塬组成,发育有厚250m左右的完整黄土地层,塬顶地势平坦开 阔,是陇东地区的主要工程建设区,为自重湿陷性场地,湿陷等级为Ⅱ～Ⅲ级;蒲茹马莲区Ⅱ)主要为蒲 河、茹河和马莲河的Ⅱ级阶地及阶地与塬间的斜坡地带,该区Ⅰ级阶地不发育,Ⅱ级阶地主要发育晚更 新世以来的黄土地层,为非自重湿陷性场地,湿陷等级Ⅱ级,地域狭窄,城市发展空间有限;泾川环柔区 Ⅲ)为泾河、环江和柔远河I级阶地,该区Ⅱ级阶地不发育,沉积有全新世的新近堆积黄土,为非自重湿 陷性场地,湿陷等级Ⅰ～Ⅱ级,地域狭窄,城市发展空间有限;合道川北区Ⅳ)为合道川、悦乐以北的广 大黄土梁峁区及白于山前缘地带,工程建设条件较差,难以从事大面积工程建设。
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.
