The normal frostheaveforce is an integral of soil frostheave stress at the freezing front along the range effected by a foundation.
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。

The magnitude of frostheaveforce is figured out by means of the half formula and half experience, namely the Equivalent Elasticity Coefficient Method.
采用半公式半经验的方法，即“等效弹性当量系数法”计算出冻胀力的量值。
