Abstract:

Natural characteristics analysis of wholly grouted bolts in soil medium was presented,and a calculation formula of natural frequency and natural vibration type was derived. For the lack of experience about the applicability of permanent anchorage in vibration environment, a dynamic test of one field under train excitation is conducted to avoid anchorage-train resonance.The results show that the first order longitudinal natural frequency of anchorage, field predominant frequency and train dominant frequency distribute in different frequency band,and train excitation causes no resonance effect with anchorages. Ralated researchs provided a important reference method for preceeding research on the applicability problem of bolt support structure in complicated environment.

Key words: slope support, anchor, natural characteristics, modal test, basic frequency, train vibration
