| 摘 要： | 针对非洲刚果(布)1号公路项目区域内的砂性土具有材料强度高、渗透性强,但表层砂性土松散,孔隙比大,压缩性高,且凝聚力差,在重载作用下易变形破坏,尤其是抗水流冲刷能力差等特点,提出了水泥处治、粘性土包边处理及竹编格栅植草防护等措施。

| Abstract: | The sandy soil in the area of Congo(Brazzaville) Highway 1 project is characterized by high material strength and high permeability,but the surface of the sandy soil is loose,macroporous,highly compressed,and poorly agglomerate,it will easily be destroyed under the heavy load,especially in poor resistance to water erosion.Based on the Sandy soil subgrade characteristic of the project,this paper advances several protective measures,such as cement control,clay packet processing and bamboo grass protection gri... |
