【摘要】 对于载荷试验的大极差,各种规范没有给出统一的规定,试验数据的处理比较随便,造成不经济或不安全。当极差大于30%平均值或最大值与最小值之比大于1.3时,承载力取值可采用离群值剔除法、变异系数折减法确定。案例计算分析表明,给出的计算公式合理、计算简单方便,可用于各种载荷试验确定承载力。更多还原

【Abstract】 Loading tests in large range condition are not uniformly prescribed in various standards and treatment of experimental data usually runs diseconomy or unsafe. When the range is larger than 30% of the average value or the ratio of maximum and minimum is bigger than 1. 3 the calculation for bearing capacity value,we can use methods such as outliers rejecting method or variation coefficient strength reduction method to calculate. Various examples show that the given formula is reasonable and easy to calculate,which can be used for determining the bearing capacity of various kinds of loading tests.更多还原
