Beam stability is critical for such an ultralow-emittance facility. Controlling and minimizing the sources and transmission of vibrations internally and externally of HEPS is an important issue for achieving the stability needed to generate and operate the high brightest beams. In this presentation, we report that the vibration levels on bare HEPS ground, the ground motion analytical model related with frequency, the designed site vibration specifications together with the careful consideration and basis. Also, the stable building design concepts, passive and active ways to minimize effects on the stability of the photon beam and critical accelerator and beamline components caused by ambient ground motion sources and the actual control effect will be introduced in detail.
