为研究预应力群锚对岩质边坡的加固效应以及锚索在节理裂隙面上的受力特点,针对岩质高边坡实际工程,作为室内模型试验的补充,采用有限差分软件对双滑面楔形体节理裂隙岩质边坡室内模型试验模型进行了边开挖边锚固施工过程模拟,结合室内模型试验结果,分析了预应力施工过程中锚索预应力变化规律和锚索体轴力分布特点及传力机制,根据位移云图随工况的发展过程定量分析了群锚加固效应。
In order to study the reinforcing effect of prestressed anchors on rock slope and the stress characteristics of anchor cable on joint fracture surface, aiming at the practical engineering of high rock slope, as the supplement of indoor model test, finite difference software Surface wedge fractured rock slope model test model of the rock side of the excavation while anchoring the construction process simulation, combined with the indoor model test results, analysis of the prestressing force during the construction of the cable prestress and anchor cable axial force distribution Characteristics and force transmission mechanism, quantitative analysis of the reinforcement effect of the group of anchors according to the development process of the displacement cloud chart.
