摘要
通过调查研究某高速公路软质岩顺层边坡特征,结合地质钻探和赤平投影,进行稳定性计算,得出该高速公路渔洞段软质岩顺层边坡下滑力,根据下滑力的大小确定了该段边坡采用抗滑桩和框架锚索的防护方案,并且对抗滑桩和框架锚索进行了内力分析。
Through the investigation and study of the expressway soft bedding rock slope characteristics,combined with the geological drilling and stereographic projection,the stability calculation is performed,and the sliding force of soft rock bedding slope of Yudong highway section is drawn.According to the size of the decline in the strength of the identified slope,the anti sliding pile and protection scheme of frame anchor box are used,and internal force analysis of anti slide pile and anchor cable frame is carried out.
