摘要： 崩塌是山区最为常见的地质灾害类型之一，灌浆法及强夯法是两种合适的崩塌体路基处理方法。分析了山区崩塌体的形成特征，对绵茂公路二岗桥崩塌体段路基采用强夯法进行了处理。通过现场测试强夯后崩塌体路基的强度参数，计算经强夯处理后崩塌体路基的强度和变形。为了满足公路交通荷载的要求，崩塌体路基在施工中及工后采用不同的沉降观测方法进行沉降监测，针对崩塌体路基的特征，给出了适合崩塌体路基变形监测的方法。

Abstract: Mass collapses are one of the most common hazards in the mountain areas. For highway embankment collapses, the pressure grouting and the dynamic compaction are the most common remediation methods. This paper presents a case history of the highway embankment collapse at Ergangqiao of MianMao Highway. The collapse body was back analyzed with strength parameters obtained from the insitu tests. The strength and deformation of the dynamic compaction treated embankment are estimated. The settlements on the highway during and after the construction are monitored by using different monitoring methods in order provide a satisfactory remediated embankment that carrying the highway operational live loads.
Key words: Collapsed Highway Embankment, Embankment Deformation, Strength and Deformation of Highway Embankment, Deformation Monitoring
