Seismic damage evaluation method of urban subgrade and pavement under near-field strong ground motion
摘要
Abstract
Previous seismic damage data indicate that the subgrade and pavement are vulnerable to earthquake damage. The influence factors of the destruction affected by earthquake are numerous, and the distribution scope of subgrade and pavement is wide which may cause great changes in the geological environment, so it's difficult to evaluate accurately the damage state of subgrade and pavement under the earthquake. The paper focuses on the subgrade and pavement of Taiyuan city. Through the research on typical seismic damage characteristic of subgrade and pavement in the earthquake prone zone and high intensity region, the seismic damage assessment method of urban highway subgrade and pavement is proposed. The results calculated by the empirical vulnerability curve and the theoretical vulnerability curve are comprised, and the difference and applicability of the two methods is verified. This will provide the help for the earthquake damage prediction of the urban subgrade and pavement, and provide theoretical support for the seismic strengthening and emergency rescue after earthquake.关键词
