摘要
本文采用四种计算模式、两种抗剪强度统计方法、三种抗剪强度指标、二种荷载,对土坡稳定进行了,可靠度分析,得到一系列实用性较强的规律。对港工地基规范的地基稳定容许安全系数的可靠度进行了校准。经分析发现地基土的总变异性具有明显规律,从而看到了地基可靠度研究的光明前景。
The paper performed the reliability analysis for slope stability by using 4 calculation modes, 2kinds of statistical metheds for determining shear strength, 3 different indexes of shear strength and 2 loads, obtained a series of rather practical regularities. The reliability of allowable safety factor of foundation stability specified in foundation stardard of port engineering has been corrected. The analysis revealed that the total variability of foundation soil presents obvious regularity, which indicated a bright fulture in studies of foundation reliability.
