| 摘 要： | 介绍了一维波动理论和土体疲劳的各种计算方法,然后对渤海某海上桩基的打桩工程的沉桩性状进行数值模拟分析,通过对不同的桩侧土体疲劳计算模式的结果做比较分析,以及与实测结果比较,表明:不同方法对沉桩性状的影响力不同,该工程中,非线性土体疲劳计算方法能较好地对砂岩层中的沉桩进行模拟。

| Abstract: | One-dimension stress wave theory and several soil fatigue methods are introduced, then numeric analysis for the properties of pile driving in one oil field of Bohai Sea is made. Comparing the results of different methods for calculation of soil fatigue and actual measurements, the effect on properties of pile driving is known. In this project, the method to calculate non-linear soil fatigue may well simulate the driving of piles in sandstones. |
