一处运营高危边坡的治理工程实践

High hazardous slope processing engineering practice

以京港澳高速公路粤境某边坡治理工程为例,通过变形监测、表面变形迹象巡查及稳定性计算等方式研究了边坡稳定性状态,综合考虑边坡变形原因、加固效果及其对高速公路运营安全的影响,确定了边坡优选加固方案,并介绍了端头锚固新型预应力锚索技术、抗滑桩竖向预应力加固技术等在边坡加固治理中取得的良好效果,以供类似工程参考借鉴。

Taking slope processing engineering in Guangdong border of Bejing-Hong Kong-Macao highway as an example, the paper studies slope stability of deformation monitoring, surface deformation examination and stability computation, comprehensively considers slope deformation causes, reinforcement effect and its impact upon highway operation safety, determines optimal slope reinforcement scheme, and introduces slope reinforcement effects of new end anchorage prestressed cable technology, anti-sliding vertical prestress reinforcement technology and so on, with a view to provide some guidance for similar engineering.
