岩土锚固技术在边坡工程中的应用

Application of ground anchoring technique in slope engineering

通过对一个实际边坡工程的分析，拟定以预应力锚索、土钉墙、喷锚支护等岩土锚固技术为主的加固方素。采用极限平衡原理进行稳定分析和剩余下滑力的计算，参考相关技术规范进行锚索和土钉墙的设计验算，结合现场试验验证锚索的可靠性并确定施工工艺，成功实现了该边坡的加固。实践表明，岩土锚固技术在边坡工程中具有方便快捷、经济可靠的突出优势。

This paper shows a case study of slope reinforcement for a bridge construction. Several types of slope reinforcement works were implemented on the slopes, including prestressed anchored cable, retaining wall with soil nail, anchor-plate retaining etc. Design of these works was based on the result of the slope stability analysis using residual sliding force method. Reliability of the prestressed anchored cable is checked by in situ pull-out test. Our experience shows that slope anchoring engineering is easy construction and cost-effective.
