历次震害资料表明，路基路面易遭受地震破坏，影响因素众多，分布范围广，导致地质环境变化大，因而准确评价路基路面地震作用下的破坏状态难度大。以太原市区公路路基路面为研究对象，通过分析地震多发区及高烈度区城市公路路基路面地震破坏典型特征，建立城市公路路基路面震害评价方法，并对比经验易损性曲线和理论易损性曲线计算结果，验证两种方法的差别及适用性，为城市公路路基路面的震害预测提供帮助，并为震前抗震加固和震后应急救援提供理论支持。
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.
