摘要
基于埋置框架的回传射线矩阵法,研究土体刚度对埋置框架速度波的影响,探讨接收点对成层地基中的有缺陷埋置框架轴向速度波的影响规律,比较有缺陷埋置框架与有缺陷单桩基础的轴向速度波.结果表明:土体刚度对成层地基中的埋置框架横向速度波影响较大,有缺陷埋置框架与有缺陷单桩基础的轴向速度波有较好的一致性.
Local defects are described by reducing Young's modulus and shear modulus of defective pile in frame structure embedded partially in soil. Based on the method of reverberation-ray matrix, the effects of soil stiffness and receiving point on velocity wave are studied for the frame structure embedded partially in layered soil, and the axial wave of defective frame structure embedded partially in layered soil is compared with that of defective pile foundation. It is found that the soil stiffness has great effect on the flexural wave, and the axial wave of defective frame structure embedded partially in layered soil is similar to that of defective pile foundation.
