摘要
根据海洋结构物中钢管桩基础呈现出的大直径、超长和深贯入的特点,采用数值模拟方法分析了钢管桩的自由站立稳定性,并与Timoshenko弹性稳定理论进行了对比,研究了不同桩端约束条件及地基土体性质对钢管桩自由站立稳定性的影响,以供参考。
The ocean structures have appeared the characteristics of large diameter, super long and deep penetration. Based on numeriacal simu- laton method and compared with Timoshenko elasticity stability theory, the influence of different constraint conditions and soil properties to the stick-up stability of steel pipe piles is analysed, so as to reference.
