摘要
徽杭高速公路B标段泥岩路堑边坡广泛采用了节点锚杆框格梁进行边坡防护与加固。为了对节点锚杆的加固效果进行评价,选取了3块地质条件不同的泥岩、泥质岩路堑边坡进行锚杆拉拔试验。文章研究了各泥岩边坡节点锚杆的拉力—位移曲线,并就试验中存在的有关疑点展开讨论,最后对锚杆试验成果的应用及节点锚杆框格梁技术进行了简要评述。
The node-anchor-rod-sash-ridge is used for the protection and reinforcement for the mud- stone slope in the Huizhou-Hangzhou Expressway B section. In order to carry out the appraial to the reinforcement effect of the node-anchor-rod, three samples of mudstone from different geolgical conditions are chosen, and the experiment of anchor-rod drawing at the agillaceous rock slope is also made. The pulling force displacement curve of node-anchor-rod at the mudstone side slope is studied and some related questions in the experiments are discussed. Finally, the paper describes the application of the experiments of anchor rod and the technology of node-anchor-rod sash ridge.
