中文摘要: 传统的边坡稳定性系数计算方法假定滑坡块条间相互作用力方向与上一块条底滑面的方向相同,但当滑面较陡与较缓或有地下水作用时,条间力方向不能保证一直与底移滑面方向相同,从而使计算有所偏差。为此提出了改进的传递系数法,推导出静水和动水作用情况下传递系数法的计算公式。最后通过新传递系数法对假定边坡稳定性系数进行计算,并与其他稳定性系数计算法计算出的系数进行对比,结果显示改进的传递系数法具有一定的精度及可靠性。
Abstract:The traditional calculation method of slope stability coefficient assumes that the direction of the interaction force between slide blocks is same with that of the sliding surface of last block. However, when the sliding surface is relatively steep or gradual, or when the ground water is involved, the same direction cannot be guaranteed, which leads to the calculation deviation. Thereupon an improved calculation method of the transfer coefficient is put forward in which the effect of still water and flowing water is taken into consideration. Finally it comes to a conclusion that the result from the calculation method of the transfer coefficient is accurate and reliable to a certain extent since the assumed slope stability coefficient obtained from this calculation method is more precise in contract with that from other calculation methods.
