摘要:
2021年5月21日21时48分34秒,云南省大理州漾濞县发生6.4级地震,中国地震局组织专家迅速进入灾区开展烈度评定和损失评估等现场应急工作。为加深业内同行对交通系统地震破坏的认识和理解,本文主要针对此次地震中交通系统的破坏情况进行宏观性描述,展现地震中交通系统的地震破坏现象,对道路和桥梁的主要震害特征进行总结,对典型震害的形成原因进行了探讨。最后,结合此次地震的破坏特点,为我国交通系统的抗震策略提出思考与建议。
Abstract:
At 21:48 on 21 May 2021, a Ms 6.4 earthquake occurred in Yangbi County, Dali Prefecture, Yunnan Province. China Earthquake Bureau (CEA) has organized experts to go to the disaster area quickly to carry out on-site emergency measures such as intensity assessment and loss assessment. To deepen the cognition and understanding of the seismic damage of traffic system for industry peers, the macroscopical seismic damage of the transportation system were present in this manuscript. It shows the damage phenomenon of the transportation system in this earthquake, and the damage characteristics of roads and bridges were summarized with the discussion of the reasons for the typical damage. Finally some suggestions were put forward for the anti-seismic strategy of the transportation system in China with the consideration of the damage characteristics in this earthquake.
