摘要
概括了低应变反射波法的基本原理与方法,在桩土体系中,将桩体简化成一维杆件。基于低应变反射波法的基本原理和波动理论,总结出相关判定准则。针对缺陷桩反射波的影响因素进行理论分析,重点分析了扩径、缩径、离析、断裂四种缺陷的影响,归纳出一些有价值的结论。最后,通过工程实例分析,针对相关结论进行验证。
The basic principle of low strain reflection wave method is recapitulated, in which the pile is simplified as one-dimen- sional pole in the pile-soil system. The theoretical deduce is presented on the basis of the basic principle of low strain reflection wave method and wave theory according to the correlative literature, as well as summary of correlative determinant rule. Then, theoretical analysis is carried on the influence factor of reflection wave of piles with defect, particularly expanded diameter, shrinking, segregation and rupture, and some valuable conclusions are summarized. Finally, the conclusions are validated by the correlative engineering.
