摘要:
以FLAC3D数值模拟计算为主要研究手段,基于结构动力学非线性有限元理论,结合某水库左岸边坡实例,对强降雨作用下滑坡体应力、位移、塑性区域进行研究,以及采用混合抗滑措施后的加固效果进行评价。结果表明:强降雨作用下,滑坡体内部主要以压应力为主,不存在拉应力;滑坡产生的最大竖向位移位于滑坡体的中下部;塑性区域面积存在集中现象贯穿滑坡体内部,滑坡处于不稳定状态。加固处理后,滑坡产生的最大竖向位移相比设抗滑装置前滑坡滑动位移量明显减小,塑性区域的面积减少,滑坡整体处于稳定状态,治理效果明显。
Abstract:
With numerical simulation calculation as the main research method,combined with an example of the left bank slope of Jinchangba reservoir,the stress,displacement and plastic area of the landslide body under heavy rainfall are studied,and the reinforcement effect after adopting mixed anti-sliding measures is evaluated. The results show that: under the action of heavy rainfall,the interior of the landslide body is mainly composed of compressive stress,and there is no tensile stress;the maximum vertical displacement generated by the landslide is located in the middle and lower parts of the landslide body;there is a concentration phenomenon in the area of the plastic zone running through the interior of the landslide body,and the landslide is in an unstable state. After the reinforcement treatment,the maximum vertical displacement of the landslide is significantly reduced compared with the sliding displacement of the landslide before the anti-skid device is installed,the area of the plastic zone is reduced,the landslide is in a stable state as a whole,and the treatment effect is obvious.
