摘要
破碎带岩石边坡,在开挖过程中都存在松弛变形现象,而且随着开挖深度和开挖面的增加,变形也会相应增大。结合实例介绍在施工中采用了预应力锚索地梁、锚杆混凝土框架植草等综合防护技术,并把信息动态施工法成功运用在锚索、锚杆施工中。
In the course of cutting broken rock mass, its side slope shall appear looseness and deformation. Further more, in the wake of deepening and spreading excavating, the deformation becomes larger. The protection measures for side slope, such as pre-stressed anchor stay ground beam, anchor rod concrete frame and ere, are taken. And the information dynamic construction method is applied successfully during the construction of anchor stay and anchor rod.
