摘要
通过对国内现有四类桥梁抗震设计规范的介绍,初步比较这几类规范的抗震设防分类及目标、设防标准、地震设计加速度以及设防概率水平等。分析设计规范存在的差异,提出设计规范的不足之处,使设计规范更具有合理性、适应性。
Based on the introduction of four kinds of bridge seismic design codes in current China, several key points of these codes are compared initially including the seismic fortification classification, target, fortification standard, seismic design acceleration and fortification probability level. The differences & inadequacies of these codes are analyzed and proposed, which will make the design code more reasonable and flexibly.
