在北方寒冷地区的许多结构物,如渡槽、桥涵和闸墩等,受到冰冻作用而产生冻胀破坏时有发生,为此国家每年都要支付一大笔维护与修理费用。对于寒区的某些结构物,设计时不考虑冻胀力的作用,这可能是造成结构物冻胀破坏的一个重要原因。本文考虑了一个合理
Many structures in cold northern regions, such as aqueducts, bridges and culverts, and sluice piers sometimes occur when frost heaving and freezing damage occurs. As a result, the country pays a large sum of maintenance and repairs every year. For some structures in the cold area, the effect of the frost heaving force is not taken into account during the design, which may be an important reason for the structural damage caused by frost heaving. This article considered a reasonable
