通过对黑龙江省Ⅰ区、Ⅱ区、Ⅲ区6座桥梁桥位处河冰抗压强度与河冰温度、加载速率试验数据的分析,建立了Ⅰ区、Ⅱ区、Ⅲ区河冰强度与河冰温度、加载速率的数学关系模型,依据模型探讨了流动河冰抗压强度的取值问题,并通过撞击力试验结果验证了河冰抗压强度取值的合理性。研究结果为计算冰压力时冰的抗压强度标准值的确定提供了参考。
Through the analysis of experimental data of ice compressive strength, ice temperature and loading rate of 6 bridges in Ⅰ, Ⅱ and Ⅲ of Heilongjiang Province, Ice temperature and loading rate. Based on the model, the value of compressive strength of flowing river ice is discussed, and the reasonable value of compressive strength of river ice is verified by the results of impact test. The results provide a reference for the determination of the standard value of ice compressive strength when ice pressure is calculated.
