    北京戒台寺滑坡治理工程动态监测

    Dynamic monitoring of the control prjecet of the Jietai Temple landslide in Beijing

    • 摘要: 北京戒台寺滑坡为一产生在地质构造发育、地层岩性差和地质环境恶劣条件下的大型破碎岩石滑坡群。滑坡规模巨大,成因复杂,总方量达920多万立方米。滑坡治理采用支挡、锚固、治水、注浆等综合治理技术。整治工程中,对滑坡进行了动态监测,通过深孔、裂缝、地表观测网等监测手段,确定滑坡的变形范围、滑动面位置、主滑方向、各滑块的滑动方向以及之间的滑动关系,同时揭示了春融以及治理工程中各工序对滑坡的影响,为动态设计、信息化施工及评价工程效果提供依据,在整治工程中发挥了关键性作用。同时,也为今后类似大型滑坡的监测提供参考。

       

      Abstract: The Jietai Temple landslide is a large smashing rock slide group which develops under the conditions of rich geological structures,bad properties of rocks and adverse circumstances.Because of its large-scale(over 9000000 m~3) and complex causes,the comprehensive treatment technologies such as retaining,anchoring,water-controlling and grouting should be adopted at the same time.Meanwhile,the dynamic monitoring system were applied in the landslide control project,from which the deformation of the landslide,the location of sliding surface,the main direction of the slip,the branch directions of the sliders and their relations among the sliding can be determined through a combination of deep borehole,cracks,the surface observation network and other monitoring tools.The monitoring results indicate that the impact of the spring melt and working procedures to the landslide played a crucial role in training projects for the dynamic design,information-based construction.The monitoring results also provided an evaluation method of project effect.The concepts given in this article provide a reference for the monitoring of similar large-scale landslide projects in the future.
