竖向荷载下微型抗压桩的性状浅谈

Discussion on micropiles carrying capacity subjected to vertical loads

在介绍微型桩特点的基础上,利用Randolph的桩周土变形模型,考虑桩身的伸长变形和桩侧土摩阻力的极限状态,推导出了单桩在竖向荷载下的变形理论解,以供相关科研院所进一步探讨研究微型桩基础的各项性质,并在此基础上建立适合工程实际的承载力公式。

Based on introducing the characteristics of micropiles,the article used Randolph model of soil deformation,considering the pile deformation and pile side friction limit,to derive out the deformation theory solution for the single pile on the vertical loads.So the scientific research institutes can use this to further their relevant research of the micropile foundation,so as to establish the formula for the practical engineering.
