Table 4, the theory of various vibration damping effect of the program prototype platform damping effect in Table 5 4 Conclusions (1) The abnormal vibration of the platform because the pile and the jacket of Volume 1, between the relative motion reduces the natural frequency of the platform The closer to the excellent frequency wave forces, resulting in increased dynamic response. (2) pile and the jacket will cause relative motion between the collisions increase the vibration platform. (3) vibration reduction measures should be used pile and grouting and other methods to eliminate relative movement between the jacket and improve the platform,<a href="http://www.franklinandmarshalluk.com" target="_blank" class="postlink">franklin and marshall clothing</a>, the natural frequency of vibration to achieve the purpose. (4) vertical leg platform of non-filling pile calculation of natural frequency of pile should be considered no contact with the jacket of extreme conditions. (5) Non-grouting piles should not be used vertical leg platform leg structure. References 1 Liu Jinkun and so on.
