冻土地区的挡土墙设计,要考虑冻融循环作用下挡墙的稳定性,提出采用拼装式挡土墙,从结构上容许挡墙有一定变形,可克服冻土对挡墙的冻胀破坏。
The design of retaining wall in permafrost region should consider the stability of retaining wall under the action of freeze-thaw cycle. It is proposed to use assembled retaining wall to allow some deformation of the retaining wall from the structure to overcome the frost heave on the retaining wall damage.
