摘要
针对基桩动测技术现状,对信号激振、桩—土振动模型中的参振质量、传感器、桩身波速与混凝土强度强度关系以及承载力动测方面的问题进行了讨论.指出了若干值得注意的问题,提出了桩—土振动模型中的参振质量测试技术改进的方法.
According to the present state of dynamic test of pile foundation, some problems such as stimulated vibration, converted vibration mass, detector, the relationship between elastic wave velocity and stiffness of pile, testing bearing capacity are discussed in the paper. Some key points solving the relevant problems are put forward. An improved method is suggested for testing the converted vibration mass.
