1969年以来,在日本的预应力混凝土铁路桥上采用了一种与活动支座一起使用的新型减震器。这种减震器的主要作用为:在连续梁桥中,分配地震时作用在梁上的纵向水平力,甚至可以分配到活动支座上;通过能量吸收,减少反应的最大值;以及减少地震时各墩顶间的相对位移。
Since 1969, a new type of shock absorber has been used with Japan’s prestressed concrete railway bridge. The main role of this shock absorber is: In a continuous beam bridge, the longitudinal horizontal force acting on the beam during the distribution of an earthquake can be distributed even to the movable support; the maximum value of the reaction is reduced by energy absorption; and the amount of earthquakes When the top of the pier between the relative displacement.
