摘要
用断裂力学方法从局部分析了碾压混凝土拱坝诱导缝的设置问题,以含典型诱导缝的坝段为对象,讨论了缝长与缝间距对诱导缝作用的影响,并提出了两种新型诱导缝方案,即诱导缝斜向布置方案和尖头诱导板方案。
Analyzed the setting of crack directors for RCC dam by way of linear elastic fracture mechanics. Aiming at the subject of a dam section with typical crack directors, it studied the effects of crack length and gap between cracks on crack directors. Two new types of crack directors are put forward, i.e. laying crack directors along slant direction, and crack inducer with sharp head.
