| 摘 要： | 选定粤赣高速公路有代表性的6种岩层,对其全、强、弱风化层组成的路堑高边坡锚索加固工程进行了69次破坏性拉拔试验。试验中对每种不同风化程度的岩(土)层采用锚固长度为1m、2m、3m的现场拉拔试验,计算出锚索加固边坡的锚固力值,为验证高边坡工程设计提供了准确的力学参数,也为全线高边坡工程的施工工艺提供指导性意见。同时,节省了大量的试验费用和时间,获得了显著的经济效益。

| Abstract: | The author presents 69 destructive drawing tests for anchor cable reinforcement of high cut slopes which consist of full mantlerock,serious mantlerock and weak mantlerock about 6 representative terranes of Yuegan expressway.It carries through different rotten terranes insitu drawing experiments for the anchoring length of 1m,2m,and 3m respectively.By calculation of anchoring force of slope reinforcement,it provides the verification of high slope engineering design with accurate mechanical parameters and also provides the construction technology of high slope engineering with instructive suggestions.It saves a lot of experiment expenditure and time,therefore achieving outstanding economic benefits. |
