摘　　要：在德昌高速公路海口镇的施工过程中,K21 ＋080 ～K21 ＋313左侧路堑边坡变形,发生滑塌.这是由于路堑施工扰动和降雨造成滑体失稳而产生的古滑坡的复活现象.阐述了古滑坡体的工程地质环境和工程地质条件及发生与发展过程,分析了滑坡形成的原因.基于动态设计的理念,及时展开补充勘察设计,通过变形观测与动态设计,适时调整工程治理措施与方案,保证了边坡的稳定.该治理方案已通过施工和运营检验,达到预期目标,为类似工程提供借鉴和参考.During the construction of the De Chang Highway in Haikou Town, left cut slope of highway section K21 ＋ 080 to K21 ＋ 313 has deformed and slumped. Because of the cutting construction disturbance and the rain, the sliding instability is severely affected and the ancient landslide has been refreshing. In this paper, the engineering geological environment, engineering geological conditions and the occurrence and development process of the slide have been stated and discussed. And the forming reason has been analyzed. Based on the concept of dynamic design, survey and design service is carried out and revised timely. Through deformation observation and dynamic design, engineering measures and schemes have been adjusted in time in order to ensure the slide slope stability. The treatment scheme has been approved by construction and operation inspections and reached its final goal, which will surely contribute to similar projects in later period.
