| 中文摘要:结合武当山风景区某护坡工程，介绍了一种预应力锚索与悬臂桩（墙）组合补强加固高边坡变形的设计方案。通过对边坡地层的补充勘察，对护坡桩结构内力的受力分析，找出了高边坡变形加剧和桩身局部裂缝的原因，设计采用了预应力锚索补强加固悬臂桩（墙）。经过长期监测，加固后3年来的桩顶最大位移累计30.1 mm，小于国家规定的规范要求。实践表明，桩锚支护补强设计安全可靠，其成功经验和体会对类似项目有借鉴意义。 |

| Abstract:This paper introduces a design plan of the combined reinforcement of high slope deformation based on pre-stressed anchor cable and the cantilever pile (wall). By the supplementary investigations of the slope geological lithology and the stress analysis on the internal force of slope protection pile structure, the causes of the high slope deformation and the local cracks of the pile were found out; the reinforced cantilever pile (wall) was designed with pre-stressed anchor cable for use. After a long time monitoring, the maximum displacement of pile head is accumulative 30.1mm in 3 years, which is less than the national regulations. It shows that the design of pile-anchor reinforcement if safe and reliable and the successful experience can be reference for the similar project. |
