紧邻110 kV高压电塔的高边坡支护设计与评价

Design and evaluation of high slope supporting project adjacent to 110 kV high voltage tower

以紧邻110 kV高压电塔的高边坡支护工程为例,探讨紧邻变形要求较高的已建建构筑物的高边坡设计过程及思路。通过分析边坡长期持续的安全监测数据,表明采用格构锚索挡墙这种主动支护系统来支护变形要求较高的高大岩质边坡效果较好,同时对于岩质边坡锚索锁定预应力可取相对高值以更好地控制边坡变形。

Taking high slope supporting project adjacent to the 110kV high voltage tower as an example,This paper discussed the design process and ideas of high slope adjacent to existing structures which need high deformation requirements.By analyzing the long-term continuous safety monitoring data of the slope,it was shown that the active support system of lattice anchor cable retaining wall had a better effect for supporting high rock slopes which need high deformation requirements.Meanwhile,anchor cable locking prestress for rock slopes could take high value for better control of slope deformation.
