| 摘 要： | 介绍欧洲岩土工程设计规范的设计原理包括作用、效应、抗力与极限状态验算不等式,分析3种设计方法用于桩基设计分项系数的取值特点.以《建筑桩基技术规范》为例对比分析中欧岩土工程设计规范基桩承载力确定方法的异同点.3个实例表明欧洲规范确定基桩承载力与国内规范确定基桩承载力平均相差25%,国内规范更为保守.

| Abstract: | The basic principle of the European geotechnical engineering design code,including the action,effect,resistance and limit state calculation inequality was introduced.The characteristics taking value of partial factors of three design approachs for pile foundation design were analyzed.Taking ＂Technical code for building pile foundations＂ as an example,the similarities and differences in determining pile bearing capacity of the China-Euro geotechnical design code were compared and analyzed.Study of three work examples illustrates the relative errors upto 25% among three kinds of design approaches of European standard and those of domestic design code.Domestic design code is more conservative. |
