Methods and Quality of Embankments Constructed in Winter
Based on the knowledge accumulated from surveys on winter construction done by the Civil Engineering Research Institute for Cold Region, the major reasons for the deformation of embankments constructed under cold weather conditions are thought to be the following: 1) work cessation necessitated by nighttime, 2) the inclusion of frost-susceptible materials, and 3) the inclusion of snow and frozen soil blocks in the materials. In this report, the authors addressed the mixing of frozen soil blocks in the material and investigated the characteristics of frozen soil as an embankment material by constructing some embankments using frozen soil and others using unfrozen soil. The construction work was done in summer and winter, and the strength and deformation of the embankments during the snowmelt season were investigated. The authors concluded that the embankments constructed using frozen soil undergo long-term subsidence during and after melting. While the strength of the embankment crown gradually increases with time, the strength inside the embankment does not increase with time.
