| 摘 要： | 将考虑尺寸效应规律的混凝土等效断裂模型应用到不同形式诱导缝等效强度公式中，得到了修正后的不同形式诱导缝的等效强度公式。同时，得到了诱导缝等效强度的变化曲线，并比较了单双向间隔诱导缝的优劣，得到双向间隔诱导缝优于单向间隔诱导缝的结论，为高拱坝中诱导缝的设计提出了建议。

| Abstract: | Concrete effective fracture model considering size effect rule was adopted to formulae for equivalent strength of different types of induced joints. The modified formulae for equivalent strength of different types of induced joints are obtained. At the same time, the variation curve of equivalent strength of induced joints is obtained; and the merits between unidirectional interval induced joints and bilateral interval induced joints are compared. It is shown that the properties of bilateral interval induced joints are better than those of unidirectional interval induced joints. Some suggestions are presented for design of induced joints in high arch dam. |
