袁家湾滑坡受人类活动控制和影响非常典型,在新构造活动以及褶皱构造和断裂构造较强烈的影响下,发育于结构松散破碎、表层风化严重的砂砾岩夹泥岩的顺倾岩层中,本文以滑坡的工程地质分析为主,结合FLAC3D数值模拟,分析了边坡在复杂的自然环境下和人类活动改造过程中的重复性、继承性、相似性和增大性的滑动特征,以及在人类改造形式下的独立性和多样性的破坏形式,揭示该滑坡伴随着人类的切坡开挖破坏逐渐加深加大,逐步向自然状态协调发展的演化过程。
Due to the control and influence of human activities, the Yuanjiawan landslide is very typical. Under the influence of the new tectonic activities and the strong folds and faults, the landslides of Yuanjiawan developed in the overturning strata of glutenite mudstone with loose structure and serious surface weathering. Based on the engineering geological analysis of landslide, combined with the numerical simulation of FLAC3D, the characteristics of sloping, repetitiveness, inheritance, similarity and increase of slides in complicated natural environment and human activities transformation are analyzed. The form of independence and the destruction of diversity under the transformation form, revealing the gradual deepening and gradual deepening of the landslide along with the cutting and destruction of human cut slope, and the gradual evolution to the coordinated development of the natural state.
