摘要
现行的桩刚度计算方法大多假设桩为刚性，而实际上桩都是可压缩的，尤其是长桩和柔性桩．压缩性非常明显。本文讨论了可压缩桩的刚度随桩长Ｌ、直径Ｄ，桩身材料弹性模量Ｅ和桩端阻力Ｒｕ的变化规律。文中给出了实测结果，证明了本文提出的桩的刚度变化规律的正确性。
Most methods for computing pile stiffness used nowadays assume the piles to be rigid.However,the actual piles are actually compressible,particularly in the case of those long pilesand soft piles,whose values of compressibility are rather clear.this paper discusses the variational regularities of compressible stiffness with respect to pile length L,pile diameter D,elastic modulus E of pile material and pile tip resistance Ru.The pile stiffness regularitiespresented in this paper are verified by measured data.
