发布时间：2018-07-13 09:19
【摘要】：削方减载因其方法简单、施工方便和抗滑效果良好,已成为常用的滑坡治理措施之一,但削方位置的不同对坡体稳定性的影响差异较大。为了直观说明这种影响,借鉴结构力学中移动荷载作用下的影响线概念,以削方减载位置的不同作为可变荷载,以每次削方减载情况下对应的稳定系数作为影响量,建立相应的滑坡削方减载影响线计算分析方法,并根据稳定系数的大小,结合工程实际,确定最优的滑坡削方减载位置。最后以某滑坡为实例,对其不同位置情况下的削方减载对应的稳定系数进行了统计,根据稳定系数的大小,结合坡体情况,直观地给出了最优的卸载位置,为合理和科学地进行坡体削方减载提供了依据。该方法计算原理简单,结果清晰直观,可对同类滑坡治理工程提供参考和借鉴。
[Abstract]:Because of its simple method, convenient construction and good anti-slide effect, cutting square load reduction has become one of the commonly used landslide treatment measures, but the influence of cutting position on the stability of slope body is quite different. In order to illustrate this effect, the concept of influence line under moving load in structural mechanics is used for reference, the variable load is the different position of cutting load, and the stability coefficient corresponding to the condition of load reduction is taken as the influence quantity. The corresponding calculation and analysis method of load reduction influence line of landslide cutting is established. According to the magnitude of stability coefficient and combined with engineering practice, the optimal load reduction location of landslide cutting is determined. Finally, taking a landslide as an example, the stability coefficient corresponding to the load reduction of the cutting side at different locations is counted. According to the magnitude of the stability coefficient and the slope body situation, the optimal unloading position is given intuitively. The results provide a basis for the reasonable and scientific load reduction of slope cutting. The method is simple in principle, clear and intuitive, and can be used as reference for similar landslide treatment projects.
