水利工程混凝土坝一旦出现裂缝,必须检查裂缝展布情况、裂缝尺寸信息,才能对大坝进行安全性评估和采取何种裂缝处理措施。传统的水利工程裂缝信息资料的分析和解释一般局限于二维、静态的表达方式,已难以满足人们空间分析的需求。本文针对水利工程混凝土坝裂缝结构的复杂性、尺寸信息量大、分析要求高,模型的准确性及更新修改等难点,融合虚拟现实和水利工程等多个交叉学科的先进理论技术,探讨了实现水利工程混凝土坝三维裂缝统计系统的制作方法。该方法在水利工程的裂缝仿真提供一种参考。
Once a concrete dam appears, it is necessary to check the crack distribution and crack size information to evaluate the safety of the dam and what kind of crack treatment measures should be taken. The traditional analysis and interpretation of cracks information data of hydraulic engineering are generally confined to two-dimensional and static expressions, which have been difficult to meet the needs of people’s spatial analysis. In this paper, according to the complexity of the crack structure, the large amount of information, the high requirements of analysis, the accuracy of the model and the updating and modification of the concrete dam in hydraulic engineering, the advanced theory and technology of interdisciplinary such as virtual reality and water conservancy project are discussed. Making method of three - dimensional crack statistical system of hydraulic project concrete dam. This method provides a reference for the crack simulation of hydraulic engineering.
