九寨沟7.0级地震公路地质灾害发育规律次生灾害防治对策
摘要:
九寨沟7.0级地震诱发公路沿线大量地质灾害,通过对公路沿线地震地质灾害的遥感解译和现场调查,表明地质灾害以中小型崩滑灾害为主,高陡斜坡路段岩土体失稳灾害突出,地震诱发岩土体失稳部位坡度一般在36°以上,树木对坡面滚石拦挡作用显著。地震诱发地质灾害主要分布在地震烈度为VIII度和IX度的区域,在川主寺至九寨沟公路的上四寨至九寨天堂段、九寨沟景区公路的五花海至箭竹海段形成2个地质灾害密集发育区。震后边坡上残留崩滑堆积物、拉裂变形岩土体、植被丧失,易于产生坡面滚石、泥石流、溯源侵蚀等次生灾害,对公路造成危害,应采取绕避、被动及主动防护、生态修复等措施。
