近十几年来,由于分析方法和计算技术的进步,水工结构模型试验的重点转向一些重大复杂或特殊问题的研究.特别是能够模拟原型材料自重的地质力学模型材料出现以后,扩大了水工结构模型试验的领域,原来一些难以完善模拟的问题,均可借助地 Over the past decade or so, due to advances in analytical methods and computational techniques, the focus of hydraulic structural model tests has shifted to the study of major complex or special problems. In particular, the appearance of geomechanical model materials capable of simulating the deadweight of prototype materials has expanded the scope of hydraulic engineering. In the field of structural model testing, some problems that are difficult to improve simulations can be supported.
