本文通过一个桩基工程的71根灌注桩的现场实测的承载力资料,说明在同一场地中桩的实际承载力值是离散的,它受多种因素的影响,因而是一个随机变量,应按数理统计的方法处理。作者建议改变传统的规定而采用文中按保证率确定单桩承载力的方法。文章还分析了单桩容许承载力随承台下桩数的变化规律。
In this paper, through field-measured bearing capacity data of 71 bored piles in a pile foundation engineering, it is shown that the actual bearing capacity of piles is discrete in the same field. It is affected by many factors and is therefore a random variable. Mathematical statistics method. The author proposes to change the traditional rules and adopt the method of determining the bearing capacity of a single pile according to the guaranteed rate in the text. The article also analyzes the variation law of allowable bearing capacity of a single pile with the number of piles under the platform.
