Embedded part base for testing dynamic stiffness of foundation

The invention discloses an embedded part base for testing the dynamic stiffness of a foundation. The embedded part base for testing the dynamic stiffness of the foundation comprises two fixing parts which are oppositely arranged, and the two fixing parts are connected and fixed through a plurality of connecting parts, a plurality of embedded parts are connected to each fixing part, and the two fixing parts are further provided with a bearing plate used for installing a vibration exciter. According to the embedded part base for testing the dynamic stiffness of the foundation, the stability, the accuracy and the fidelity of vertical vibration and horizontal rotary vibration signals can be improved. 本发明公开了一种用于地基动刚度测试的预埋件基座，所述用于地基动刚度测试的预埋件基座包括相对而设的两条固定件，两条固定件之间通过若干连接件连接固定；每条固定件上分别连接有多个预埋件；两条固定件上还设置有用于安装激振器的承托板。本发明提供的一种用于地基动刚度测试的预埋件基座，能够提高竖向振动和水平回转振动信号的稳定性，准确性，保真性。
