Improved Methodology for Seismic Estimation of Highway Based on Wenchuan Earthquake

Abstract

Highway network not only is an important component of the lifeline systems, but also plays a crucial role in earthquake relief after a disastrous earthquake. Quick and accurate estimation of highway engineering seismic damage can provide scientific basis for earthquake disaster prevention planning. Based on Yi-ping CHEN’s empirical methodology, this paper uses the national standard earthquake damage index. And highway classification, fortification intensity and other parameters are also added to make the model integrated and accurate. Compared with the real seismic damages in Wenchuan earthquake, the results of using original and the improved methodologies show that the improved model is more accurate.
