中文摘要：
对桩基计算理论进行了概括，介绍了利用ADINA软件进行桩基荷载-沉降全过程计算的方法和步骤，探讨了几个主要参数对计算结果的影响；对2根试验桩进行了内力测试，并利用ADINA软件模拟了荷载-沉降全过程，得出了不同土层桩侧摩阻力的变化规律，并与实测值进行了对比；分析了ADINA计算系统的优势及不足，提出了使计算更符合实际的改进方向。结果表明：ADINA计算结果与实测结果吻合良好，可对桩基础进行优化设计。
英文摘要：
The calculation theories of pile were summarized. The calculation methods and procedures of load-settlement whole process were introduced. Several main calculation parameters and their influences on the results were discussed. The load-settlement whole process of two testing piles were simulated by using ADINA software, and the changing rules of pile skin friction for different soils were obtained. The values of side soil resistance of different soil sections were calculated and compared with testing values. The superiority and shortage of ADINA calculation system were analyzed and the way for improving ADINA calculation was put forward. The results show that the calculated results agree well with the measured results for ADINA, and the optimizing design is made for pile foundation.
