摘要
对黄河下游堤防各类土体凝聚力与内摩擦角之间的相关性及其对堤防稳定性指标的影响进行了分析,结果表明:土体强度指标的互相关性对黄河下游堤防边坡稳定性评价影响较大;采用固定的土性参数来计算其稳定性是不切合实际的;土体抗剪强度参数的相关性是计算边坡可靠指标的一个极其重要的因素。
The paper analyzes the relativity between cohesion and angle of internal friction of various soil mass of the embankments on the lower Yellow River and its influence to the stability index of the embankments.The outcomes show that the influence of mutual relativity of intensity index of soil mass to the evaluation of slope stability of the embankments on the lower Yellow River is greater;to calculate the stability by using fixed parameter of soil character is not practical and;the relativity of shearing resistance parameter of soil mass is of an extremely important factor for calculating reliability index of slopes.
