| 摘 要： | 锚杆是将铁丝格栅和绿化基材混合物固定在坡面岩体上,且埋入岩体深处的受拉构件。锚杆、铁丝格栅与岩体共同承担外荷载、基材混合物层的自重应力等,岩体结构类型、边坡高度及坡比不同,锚杆的锚固深度和间距亦不相同。本文以安楚高速公路不同坡比的石灰岩深层稳定岩石边坡厚层基材喷射植被护坡技术为切入点,通过建立静力平衡方程以及锚杆的抗拉抗拔稳定性验算,对锚杆受力进行分析计算,找出影响锚杆的锚固深度和间距的具体因素,并算出锚杆最佳锚固深度和最佳间距的表达式。

| Abstract: | Anchor is the tension member buried in deep rock,which is used to fix wire grid and green base material mixtures on the slope surface of rock.Anchor,wire grid and rock bear the exterior loads,gravity stress of base material mixtures together.As the rock structural types,slope heights and slope ratio differ,the anchorage depths and anchor spans are different.This article started from the thick layer base material spraying bio-slope-engineering technology on different ratios of limestone deep formation stable rock.Through the establishment of static balance equations and stability check on anchor tensile strength,the stress analysis to the anchor was conducted.Then the specific factors affecting the anchorage depths and anchor spans were found,and the expression on the optimal value of them was given. |
