[提要]  在工程设计实践中，根据《建筑桩基技术规范》(JGJ94-94)计算桩基沉降量往往偏大很多，甚至计算值是实测值的10倍。阐明了产生这种差距的主要原因，并提出了比较符合桩基实测沉降值的修正计算方法。

In engineering design practice, the pile settlement calculated base on JGJ94-94 code is much larger than the practical settlement, even calculating numeric is ten times of testing numeric. Deviation between calculating and testing settle-ment is interpreted. And modified calculation method is proposed.
