摘　　要：针对当前桥梁防震挡块设计具有的盲目性,与“越强越有效”的指导思想相反,有关建造“一次性”挡块,阻断力的下传,以便在大地震中,使挡块起到“保险丝”的作用,保护隐蔽的、难于修复的下部构造和基础的思路,具有一定的合理性。Because the design of bridge shockproof block takes on blindness at the moment, and is opposite to the thought of direction “more strong more effective”. Construct only one time block, and inter- diction force sends down, in order to make the block has the effect of fuse and protects convert and nonrepaired infrastructure and basis. The train of thoughts has stated reasonable.
