frost-heave force

The normal frost heave force is an integral of soil frost heave 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 frost heave force 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。

By regarding testing mechanics behaviors of frozen soil frost heave as the research background, a hydraulic force control system was designed on the basis of valve control asymmetric cylinder.

以测试冻土冻胀的力学行为为研究背景，设计了一套基于阀控非对称缸的液压力控制系统。
