摘要: 讨论了新出版的《水工建筑物抗冰冻设计规范》(DL/T5082-1998)(98版)中的地表冻胀量对法向冻胀力影响的问题.认为地表冻胀量是冻胀率沿整个冻深的叠加;法向冻胀力则是在冻结锋面上冻胀应力沿基础影响范围之内的积分.法向冻胀力与地表冻胀量没有直接联系.

关键词: 地表冻胀量, 冻胀率, 法向冻胀力, 冻结锋面, “微型千斤顶”

Abstract: The effect of surface amount of frost heaving on normal frost heave force in the new edition of《Design Specifications of Hydraulic Structures Against Ice and Freezing Action》(DL/T5082-1998) was discussed. The surface amount of frost heaving is an integral of frost heaving ratio along the full freezing depth. The normal frost heave force is an integral of soil frost heave stress at the freezing front along the range effected by a foundation. Therefore, it is no relationship between normal frost heave force and surface amount of frost heaving.

Key words: surface amount of frost heaving, frost heaving ratio, normal frost heave force, freezing front, micro jack
