摘　　要：梅河高速公路在2005年6月强降雨诱发下,K21段坡体发生了约10×104 m3的大规模变形,严重影响了正常运营。为有效控制坡体变形,确保公路安全,分析了坡体的变形特征及成因,并完成了坡体的紧急抢险工程与综合治理设计。实践证实,坡体经综合治理后已处于稳定状态,达到了预期目的。Because of heavy rainfall in June 2005,K21 section slope in Meizhou-Heyuan Expressway appears 10 × 104 m3 large-scale deformation,seriously affecting normal operation.In order to ensure highway safety,the characteristics and causes of slope deformation are analyzed.Based on this,emergency repair work is carried out and comprehensive control measures are taken.It is proven from practice that the slope is under stable condition after comprehensive control,which achieved the expected purpose.
