Calculation of Reliability Index and Resistance Partial Coefficients of Bored Pile Ultimate Bearing Capacity
-
摘要: 在试验资料整理和分析基础上,利用桩的可靠性原理和分析方法,提出了钻孔灌注桩的承载力表达式, 计算确定了抗力分项系数,并结合工程实例进行了承载力验算。Abstract: Based on treatment and analysis of the testing data of piles, a formula for calculatingthe ultimate bearing capacity of bored piles is proposed by employing the reliability principle and analysis method for piles. Resistance partial coefficients of piles are determined by computation, and the computed bearing capacity of this type of piles is checked by engineering example.
