摘要
结合小湾工程1210m高程平面坝肩稳定加固地基方案,以地质力学模型试验为主要研究手段,并与有限元计算相结合,对小湾工程1210m高程平面坝肩稳定性和加固措施的合理性进行了研究。分析了加固条件下坝肩及坝体变形分布特征、坝肩失稳的破坏过程、破坏形态和破坏机理,确定了坝肩超载稳定安全度,为工程设计和施工提供了参考依据。
Based on foundation treatment scheme for abutment reinforcement at EL 1210m at Xiaowan hydropower project,the stability and rationality of the reinforcement measures are researched in his paper with geomechanical model test for a major research tool,coupled with the finite element method.The deformation distribution characteristics,destruction process of abutment failure,failure pattern and mechanism are analyzed for abutment and dam body under reinforcement condition to determine the safety and stability of overloading abutment and provide reference for design and construction of the similar project.
