Analysis and treatment of collapse and dangerous rock Mass disaster at exit of Guergou Tunnel LIU Zi-Qiang MA Hong-Sheng MU Yun-Juan Sichuan Provincial Department of Transportation Highway Planning Survey, Design and Research Institute, chengdu, 610041, China Sichuan Academy of Social Science chengdu, 610071, China Abstract: The Collapse dangerous rock is one of the most common geological disasters. There are a lot of geological hazards of collapse and dangerous rock on both sides of the mountain along the Wenma highway, Impact of collapse on the safety of route construction and operation. Through the analysis of the characteristics, forming mechanism, influencing factors and stability of the collapse rock at the exit of Guergou tunnel, the corresponding measures are adopted for comprehensive treatment of collapsed rocks, and the control effect is obvious. Therefore, it has a certain guidance and reference significance for the management of Wenma Highway and other similar projects Keywords: The Wenma highway; The Guergou tunnel Collapse rock mass; Disaster nalysis; Administe 古尔沟隧道出口崩塌危岩体灾害分析与治理 刘自强!马洪生2牟云娟2 四川省交通运输厅公路规划勘察设计研究院,成都610041 四川省社会科学院,成都610071 摘要:崩塌落石是山区常见的地质灾害之一。汶马高速公路沿线两侧山体发育大量的危岩 体,崩落后对路线施工运营安全造成影响。本文通过对古尔沟隧道出口崩塌危岩的特征、形 成机制、影响因素和稳定性分析,针对崩塌危岩采用相应的综合治理措施,治理效果明显。 因此,对汶马高路公路及其他类似工程治理起到一定的指导和借鉴意义。 关键词:汶马高速公路:;古尔沟隧道:崩塌危岩体:灾害分析:治理 0工程概况 古尔沟隧道出口崩塌危岩体位于古尔沟镇古尔沟村国道317线左侧,地理坐标为Ⅹ= 486956730,Y=536688599隧道出口边坡陡峻,坡度60~85°高差大于300米,坡向320° 坡面出露岩体破碎、裂隙发育,岩体多被裂隙切割成块状,一般个体大小0.4*04*0.8m,个 刘自强(1977-),男,四川资阳人。高级工程师,硕士,主要从事地质灾害调查及治理、公 路岩土工程勘察设计工作。通讯地址:E-mail:2316731567@qq.com (c)1994-2019ChinaAcademicJournalElectronicpUblishingHouse.Allrightsreservedhttp://www.cnki.netAnalysis and treatment of collapse and dangerous Rock Mass disaster at exit of Guergou Tunnel LIU Zi-Qiang1 MA Hong-Sheng2 MU Yun-Juan2 Sichuan Provincial Department of Transportation Highway Planning ,Survey ,Design and Research Institute,chengdu,610041,China Sichuan Academy of Social Science chengdu，610071,China Abstract: The Collapse dangerous rock is one of the most common geological disasters.
