Slide-resistant pile and anchor cable framework combined type active reinforcing method for side slope
The invention discloses a slide-resistant pile and anchor cable framework combined type active reinforcing method for a side slope. The slide-resistant pile and anchor cable framework combined type active reinforcing method comprises the following steps: measuring mechanical parameters before and after the side slope is softened, establishing a two-dimensional geological generalized model, and setting boundary conditions; taking softened rock-soil mechanical properties into the two-dimensional geological generalized model, calculating a first safety coefficient F1, and judging whether active reinforcing is performed or not; setting a combined reinforcing way and reinforcing parameters for a slide-resistant pile and anchor cable framework according to the two-dimensional geological generalized model and a potential slide layer state; taking original rock-soil mechanical parameters into the two-dimensional geological generalized model, calculating a second safety coefficient F2 for the reinforced side slope, and judging whether engineering stability is met or not. Based on rock-soil physical and mechanical parameter changes before and after excavation, slide-resistant piles and anchor cables are adopted to perform active reinforcing after excavation; and strength, at an initial state, of rock soil is utilized to prevent rock-soil strength from greatly reducing due to the fact that the excavated slope is deformed and softened.
本发明公开了一种抗滑桩与锚索框架联合式边坡主动加固方法，其步骤包括：对边坡进行软化前后的力学参数进行测定，建立二维地质概化模型，并设置边界条件；将软化后岩土力学参数带入二维地质概化模型，计算出第一安全系数F1，并判断是否进行主动加固；根据二维地质概化模型及潜在滑动层状态，设置抗滑桩与锚索框架的联合加固方式及加固参数；将初始岩土力学参数带入二维地质概化模型，对加固后的边坡计算出第二安全系数F2，并判断是否符合工程稳定性。本发明基于开挖前后岩土物理力学参数变化，开挖后采用抗滑桩与锚索框架对边坡进行主动加固，利用岩土初始状态的强度，避免开挖后坡体变形软化导致岩土强度大幅下降。
