最后，根据锯齿型冰力模型得出自激振动与连续挤压破坏发生的转变速率。
Then transition velocity of self-excited vibration and continuous crushing is got bu the model of saw-tooth force function.
基于现场原型结构测量，研究了冰与柔性直立结构作用产生挤压破坏过程形成的交变冰力。
Based on full-scale structural tests, the cyclic ice loads formed in crushing failure when ice interacts with vertical compliant structures are investigated.
鉴于目前固体破坏力学不能准确描述冰的挤压破碎过程，理论和数值方法的应用非常困难。
Since modern damage mechanics is not able to describe the crushing process of ice sheet accurately, it is fairly difficult to study crushing ice force using theoretical or numerical methods.
