Initiative strengthening method specific to unstable slope
The invention discloses an initial strengthening method specific to an unstable slope. The initial strengthening method includes the steps that mechanics parameters obtained before and after softeningof the slope are measured, and whether initiative strengthening needs to be conducted or not is judged; a two-dimensional geological generalized model is established, and boundary conditions are set;rock and soil mechanics parameters obtained after softening are brought into the two-dimensional geological generalized model, a first safety coefficient F1 is calculated, and whether initiative strengthening needs to be conducted or not is judged; a strengthening manner and strengthening parameters of an anchor cable frame are set according to the two-dimensional geological generalized model; and initial rock and soil mechanics parameters are brought into the two-dimensional geological generalized model, a second safety coefficient F2 is calculated on the strengthened slope, and whether thesecond safety coefficient conforms to project stability or not is judged. By means of the initiative strengthening method, rock and soil physical and mechanics parameter changes obtained before and after excavation are taken into consideration, the anchor cable frame is immediately adopted for conducting initiative strengthening on the slope after excavation, the strength in the rock and soil initial state is sufficiently utilized, the phenomenon that the rock and soil strength is greatly reduced when the slope is deformed and softened after excavation is avoided, and slope plants can be effectively protected against damage.
本发明公开了一种针对不稳定边坡的主动加固方法，其步骤包括：对边坡进行软化前后的力学参数进行测定，并判断是否进行主动加固；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，设置锚索框架的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。本发明考虑了开挖前后岩土物理力学参数变化，通过开挖后立即采用锚索框架对边坡进行主动加固，充分利用岩土初始状态的强度，避免开挖后坡体变形软化导致的岩土强度大幅下降，能够有效保护坡体植被不受破坏。
