【摘要】 滑坡是指斜坡上的土体或者岩体,受河流冲刷、地下水活动、雨水浸泡、地震及人工切坡等因素影响,在重力作用下,沿着一定的软弱面或者软弱带,整体地或者分散地顺坡向下滑动的自然现象。运动的岩(土)体称为变位体或滑移体,未移动的下伏岩(土)体称为滑床[9]。滑坡常常给工农业生产以及人民生命财产造成巨大损失、有的甚至是毁灭性的灾难。我国是一个多山国家,目前滑坡地质灾害频发对国民生产造成了重大损失,对滑坡的研究和治理就显得尤为迫切。本文的主要工作：(1)以安阳市林州市一处大型推移式滑坡为研究对象,通过踏勘、工程地质测绘、钻探、槽探、原位测试、室内土工试验等手段确定了滑动体和滑动带土体的天然状态和饱和状态下的物理力学参数。对滑坡体的主要特征及稳定性进行了分析,对滑坡危害进行了预测。(2)通过计算自重、自重和暴雨状态、自重和地震状态三种工况下边坡的稳定系数,得出在自重状态下滑坡处于稳定状态,但是在后两种工况下坡体稳定安全系数小于1.0,坡体会下滑。(3)通过对几种治理方案进行技术经济比较,提出了抗滑桩+地表截水的治理形式,设计了一排抗滑桩及数条地表截水沟。通过验算,满足边坡稳定性要求。通过技术经济比对,该治理方案可靠,经济性合理。更多还原

【Abstract】 Landslide is a kind of natural phenomenon, which refers to soil or rock mass on the slope affected by factors such as river erosion, groundwater activity, rainwater immersion, earthquake and artificial cutting slope, under the action of gravity, along a certain soft surface or weak The belt slides in a downwardly or downward direction, either wholly or in a dispersed manner.Movement of the rock (soil) body known as the body or slip body, not moving the underlying rock (soil) body known as the slide bed.Landslides often cause huge losses to industrial and agricultural production as well as people’s lives and property, and some even devastating disaster. In our country, there is a lot of mountain countries. At present, it is very urgent to study and control the landslide, which has caused great loss to the national production.The main work of this paper:(1) Study on a large scale lapse type landslide in Linzhou city of Anyang, Through exploration, engineering geological mapping, drilling, trenching, in-situ test and laboratory soil test methods such as physical and mechanical natural state of sliding body and sliding zone soil and saturated parameters are determined. In this paper, the main characteristics and the stability of the landslide are analyzed, and the harm of the landslide is predicted.(2) By calculating the stability coefficient of the slope gravity, gravity and rainstorm, gravity and seismic conditions under three different conditions, obtained under gravity conditions of landslide is in a stable state, but in the two conditions of the slope stability safety coefficient is less than 1, the slope will decline.(3) Based on the technical and economic comparison of several treatment schemes, the control form of anti slide pile and surface water cut was proposed. Through checking calculation, to meet the requirements of slope stability. Through technical and economic comparison, the governance program is reliable and economic rational.更多还原
