| 摘 要： | 针对运用块体理论分析岩质边坡稳定性问题存在多种不确定性的混合体,提出用盲数表达具有不确定性的计算参数,将盲数理论引入楔形关键块体稳定计算方法中,给出了一种安全系数的计算方法.通过盲数运算可得到安全系数在不同取值区间内的可信度,较好地减少了因取单一值计算结果中主观因素的影响.实例研究结果表明,该方法方便灵活、有效、实用、计算结果较为可靠、合理.

| Abstract: | The key of the stability analysis for rock slope by block theory is the stability analysis of key block.Uncertainty information such as random,fuzzy,gray,unsure message widely exists in the geotechnical engineering.and the complexity of the practical situation,calculation parameters are usually the mixture of multiuncertainty.Based on this point,using the blind data to express the uncertainty of the calculation parameters,the blind data theory is applied to the stability analysis method of wedge-shaped key ... |
