| 中文摘要:边坡治理工程常用到喷锚支护形式。护坡面层采用素混凝土或者钢筋混凝土，耗用建材量大，不经济。公路边坡往往还需要环保观感要求，灰色的混凝土跟周围环境不协调。本文提出一种“锚杆加固+土工格栅护坡+客土喷播绿化”的新型生态边坡复合支护形式，并设计试验段进行研究。通过理正岩土软件计算，边坡稳定性、锚杆承载力均满足设计要求。试验段锚杆采用GFRP锚杆，面积100 m2。施工完成后，对比传统土钉墙混凝土面层和格构梁锚杆护坡支护形式，该形式具有施工快捷、经济适用等优势，既可用于加固边坡又具备绿色环保功能。 |

| Abstract:Bolting and shotcreting are commonly used in slope treatment. The retaining surface is made of plain concrete or reinforced concrete, which consumes a large amount of building materials and is expensive. Gray concrete is not in harmony with the surrounding environment, because highway slopes often require environmental awareness. In this paper, a new ecological slope compound retaining form of “bolting + geo-grid slope + green spray on borrowed soil” was presented and used over an experimental section. Calculation indicated that the slope stability and the anchor bearing capacity all meet the design requirements. The test section anchor rod adopted the GFRP anchor rod, the area is 100m2. After construction, compared with the traditional soil nailing wall concrete surface layer and lattice beam anchor bar retaining form, this form has the advantage of quick construction, economic application, which can be used to reinforce the slope and have green environmental protection function. |
