以猴子石滑坡为例,利用数值模拟方法,计算了滑坡条块间作用力倾角.对比分析了半精确条分法中传递系数法、罗厄法、美国陆军工程师团法、简化的简布法及实用递推法所确定的条块间作用力倾角与数值模拟值计算结果的差别.讨论了半精确条分法关于条块间作用力倾角的假定对滑坡稳定系数计算精度的影响,并与精确条分法的计算结果和基于数值模拟值的条块间作用力倾角所计算的力的平衡条件下的稳定系数进行了比较.详细论证了现行主要半精确条分法的精度与适用性.
Taking the monkey stone landslide as an example, the force dip between landslide blocks was calculated by numerical simulation method.The transmission coefficient method, the Roehauser method, the US Army Corps of Engineers Corps method, the Simplified Jane Bush method And the practical recursive method to determine the difference between the results of the dip angle and the numerical simulation results of the bars.The effects of the assumption of the dip between bars on the calculation accuracy of the landslide stability coefficient are discussed, The results of the exact bar method and those based on the numerical simulations show that the stability coefficients under the equilibrium condition of forces are compared and the accuracy and applicability of the current main semi-precision bar method are demonstrated in detail.
