| 摘 要： | 由树根桩通过横梁和锚杆连接而成的挡土结构，应用于膨胀土地区滑坡整治工程中，表现出较好的空间效应和较大的侧向刚度，可以有效地限制侧向变形，发挥结构的整体受荷特性，调动土体的自稳能力；树根桩施工过程中的二次劈裂注浆技术使桩体可靠地锚固在滑床土体中，并加固滑体，防止土体中渗流裂隙的发展。

| Abstract: | The Compound Retaining Structure,composed of root piles and earth-bolts through the top-beam,is applied to treatment of expensive-soil slope.This structure has rather fine space effect and biggish side rigidity,which can limit the side deformation effectively;At the same time,the cooperation of root piles and bolts can exert the speciality of retaining loads wholly and arosing the earth's self-stabilization ability.Grouting technology during the construciton of root pile can bolt the piles in the slope bed,reinforce slope body and stop the development of seeping fracture. |
