摘要
考虑了桩周土摩阻力和桩侧土线弹性横向约束,利用Timoshenko能量法原理,推导了具有不同桩顶和桩端约束条件的细长桩压屈临界荷载计算公式.并给出了具体算例,与其他文献相比较,该方法简单,易于实用.
Considering side friction of soil along the pile shaft and side linear elastic lateral restraint,the formulas of buckling loads for slim piles are deduced by using Timoshenko energy method. The formulas can consider different constraint conditions of pile top and end.Furthermore,an example is given and compared with other method.It is proved that the calculated method adopted in this paper is simple and practical.
