摘　　要：冰及冰凌的威胁是与人民生命财产安全密切相关的重大问题。由于冰问题的复杂性,可靠地确定冰荷载的方法应该是:理论(包括公式计算)的方法与室内模型实验或现场观测密切结合,因此冰模拟实验已成为工程设计及工程论证不可缺少的工具。通过对冰模拟实验以及低温冷冻模型冰特性的论述和水工结构物冰荷载模拟实验的实例,阐述了冰模拟实验技术对水工建筑物冰问题研究的必要性和适用性。The threat of ice is an important problem closely related to the safeties of lives and property of the people. Due to the complexity of the problem, the reliable method of estimating the ice load is to be combining the theoretic method （including formulation） with the model test or field observations. So the ice model test is an indispensable tool for the engineering design and the demonstration concerned. Therefore, the necessity and applicability of the technique of the ice modeling test for the research on the ice problem in construction of the hydraulic structures are expatiated based on the ice model test, the discussion on the characteristics of frozen modeling ice and a case study on the ice load modeling test for a typical hydraulic structure herein.
