| 摘 要： | 介绍了玻璃钢螺旋锚、土工格栅、土工泡沫和土工合成材料黏土垫(GCL)在修复河南邓州市膨胀土渠道滑坡中的应用。玻璃钢螺旋锚用来锚固水上坡的混凝土框架梁和水下坡的混凝土板,土工格栅提高渠坡抗整体滑动的安全系数,土工泡沫用以减小混凝土板衬砌下的膨胀力,GCL用作混凝土板下的防渗垫层。文中给出设计方法、监测方案和修复工程的竣工情况,还将玻璃钢螺旋锚方案与其他修复方法,如换填非膨胀土法、抗滑桩法以及土工格栅分层加筋法做了技术和经济比较,说明了该法的优越性。 |

| Abstract: | The application of FRP screw anchor,geogrid,geofoam slab and geosynthetics clay liner(GCL) in repairing slide of canal slope of expansive soils has been introduced in this paper.The FRP screw anchor was used to anchor the concrete frame girder above the berm and concrete slab below the berm,the geogrid improved the factor of safety against complete sliding surface,the geofoam slab was used to reduce the expansive force under the concrete slab and GCL was used as seepage prevention liner under the concrete slab.And.The paper presents a design method,a monitoring plan and information of post-construction for this project.The technical and economic comparisons of the application of FRP screw anchor with other schemes such as non-swelling soil replacement method,anti-slide pile and reinforcement of geogrid in layers prove that this scheme is priority method. |
