2008年5月12日，四川省汶川县发生里氏8.0级地震，造成重大生命财产损失。此外，受灾最严重的地区还引发了大量山体滑坡和边坡失稳，对基础设施和公共设施造成了灾难性的破坏。此外，地震造成的大量不稳定斜坡有可能在相当长的一段时间内造成损害。这些边坡的多样性和相应的处理与场地的地形和地质条件有关。决定记录和确定地震引起的一些主要边坡失稳及其处理方法。本文通过实地勘察，了解了都江堰市某公路的现状。该案例对地震灾区的灾后重建和今后的防灾减灾工作具有重要的指导意义。
On May 12, 2008, a magnitude 8.0 earthquake hit Wenchuan County, Sichuan Province resulted in great loss of life and properties. Besides, abundant landslides and slope failures were triggered in the most seriously hit areas and caused disastrous damages to infrastructures and public facilities. Moreover, abundant unstable slopes caused by the quake have the potential to cause damages for a considerable long period of time. The variety of these slopes and the corresponding treatments are connected with the topographical and geological conditions of the sites. It is decided to document and identify some of these major slope instabilities caused by the earthquake and their treatments. The paper shows the condition of a road in Dujiangyan through in situ explorations. The case history showed significant implications to the reconstruction of the quake-hit regions and future disaster prevention and management works.
