摘要
碾压混凝土筑坝具有节省投资,施工速度快及简化温控技术等优点,因此在国内外得到了广泛推广,但随之而来的层间抗剪特性成为急待解决的问题,层间抗剪强度已成为决定碾压混凝土坝抗滑稳定的重要因素,结合同家“八·五”科技攻关项目“普定碾压混凝土拱坝层间抗剪特性研究”,本文进行了碾压混凝土立方试件单轴及多轴抗剪试验,建议了多轴抗剪破坏准则,可以作为工程设计的依据。
Because of its obvious advantages such as the saing of investment, simplification of construction process and temperature-control technology, RCCDs are being built widespreadly in the world. However, the shear strengths between joints in RCCDs are the key factor to determine the dam safety. In accordance with the requirement of national key project of the Eighted Five -Year Plan, the authors carry out uniaxial and multiaxial shear tests with cubic RCC specimens and propose the multiaxial shear failure criteria, which can be a foundation for engineering design.
