边坡锚索锚杆防护位置选取浅析

Analysis on Protection Location Selection of Slope Anchor Cable & Anchor Rod

文章以某高速公路边坡锚索与锚杆联合防护设计为例,对不同锚索位置的边坡等效塑性应变、坡面最大水平位移及相应的安全系数进行了模拟计算分析。结果表明,锚索防护位置处于开挖坡面的最上部最合理,可用最节约的成本达到相对合理的设计结果。

With the joint-protection design of slope anchor cable anchor rod in an express-way as the case,the article conducted the simulation calculation analysis on the equivalent plastic strain of slope,maximum slope horizontal displacement and corresponding safety factors in different anchor cables locations.The results showed that the anchor cable protec-tion location on the top of excavation slopes is most reasonable,which can achieve the relatively reasonable design result with the most cost savings.
