海上多腿结构前冰的非同时破坏系数及其概率分布

Non-simultaneous failure of ice before multi-leg structures and its probability distribution

到目前为止,工程设计中都不考虑冰的非同时破坏,造成了冰力设计值的偏高和工程浪费。通过冰力模型试验,研究了双桩、单排多桩、正方形布置的四腿结构前冰的非同时破坏现象,给出了冰非同时破坏系数及其概率分布特征,可作为工程设计的参考标准。

So far, the nonsimultaneous failure has not been considered in design, thus the designed ice force value tend to be higher and the cost of the engineering was wasted. Through the ice force model tests, the authors have studied the nonsimultaneous failure of ice before doublepile, singleline multipile and square fourleg structures. The nonsimultaneous failure coefficients and its characteristics of probability distribution are given, which can be applied as references for engineering design.
