摘要
2019年11月1日,太原市新建天龙山路K2+180~K2+215段左侧边坡发生崩塌,崩塌体沿岩体层面发生滑移,脱落岩体底部卡入1号大桥梁体与边坡之间,垮塌方量为320 m 3,部分岩体垮塌坠入桥底,该崩塌灾害给该段桥梁安全和车辆通行带来严重威胁,急需进行工程治理。设计结合现场地形地貌、岩体岩性、结构等特点,进行了崩塌成因机制分析,并结合现场实际,综合采用锚索地梁+主动防护网的措施进行治理,取得良好治理效果。
On November 1,2019,the left side slope of K2+180~K2+215 section of newly-built Tianlongshan Road in Taiyuan collapsed,the collapse mass slipped along the rock mass layer,the bottom of detached rock mass stuck between the beam body and the slope of No.1 Bridge,the collapse volume was 320 square meters,and some rock mass collapsed into the bottom of bridge,the collapse disaster seriously threatened the safety of bridge and vehicles traffic in this section,urgent need for engineering treatment.The design combined with the topography,lithology of rock mass,structure and other characteristics,this paper made collapse mechanism analysis,and combining with the actual situation of site,comprehensively used the measures of anchor cable ground beam+active protection net for treatment,achieved good treatment effect.
