| 摘 要： | 简要分析了裂缝开度变化的影响因素在工程中的重要意义，针对传统数值计算方法的不足提出了大坝裂缝的变精度粗集模型。首先介绍了标准粗集理论和变精度粗集理论的基本原理以及两者的主要差别．然后建立了大坝裂缝的变精度粗集模型，并通过属性离散化和属性约简得到大坝裂缝的主要影响因素，最后给出了这一模型在工程中的实际应用。

| Abstract: | In this thesis, the importance of researching the affecting factor of crack was briefly analysed. And then a new method based on variable precision rough sets model(VPRS) was presented. Firstly, the difference of standard and variable precision rough sets was introducd, the VPRS model of dam crack was established, and then the main factors were extracted through discretization and ruduction, finally a practical application of the model was illustrated. |
