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．
In view of the status quo of pile foundation dynamic measurement technology, the problems of signal excitation, vibration quality of pile-soil vibration model, the relationship between sensor and pile velocity and concrete strength and strength, and bearing capacity dynamic measurement are discussed. Several notable problems are pointed out and an improved method of parametric vibration measurement in pile-soil vibration model is proposed.
