广河高速公路惠州段K81路堑滑坡成因分析、治理及监测措施

摘要

The cutting slope landslide between K80+920~K81 +260 section of Guang-He Expressway is a typi-cal cutting slope disease.Based on site investigation,the engineering geological condition of the cutting landslide has been found out,the evolutional history of the cutting landslide has been investigated and emergency measures have been taken.Combined with drilling and monitoring data,the causes of the landslide have been analyzed, landslide direction and mechanical parameters for the landslide surface have been determined.Therefore,treat-ment measures for landslide reinforcement and monitoring methods have been proposed,which could provide use-ful experience for the design and construction of similar projects in Guangdong Province.%广州至河源高速公路惠州段K80＋920～K81＋260段右侧路堑滑坡是典型的路堑边坡病害。通过现场勘察，查明了滑坡的工程地质条件，研究了滑坡的演变历史，对滑坡采取了应急抢险措施。结合钻探资料和监测资料，分析了滑坡的成因，确定了滑坡滑动的方向和滑面的力学参数，从而有针对性地提出滑坡加固治理措施和监测建议，对广东地区类似路堑滑坡的治理提供了有益的经验。
