摘　　要：以我国唐山、海城、通海等大地震中７～９度区内遭受不同程度震害的１００座公路桥梁作为样本，采用数理统计方法，给出引起公路桥梁震害的各种因素的影响系数，提供了适合我国现有公路桥梁震害预测的简易实用方法。In this paper 100 highway bridges damaged to different degrees are selected as samples. These bridges are located at intensity 7 to 9 zones of Tangshan, Haicheng and Toughal Earthquakes. Using mathematical statistics, we have obtained the factors of the effects of various characteristics of bridges on the seismic damage and provided a simple and practical method for predicting seismic damages of existing highway bridges.
