摘要 本文引用强度储备的概念,通过拱坝坝肩稳定的三维地质力学模型试验,采用变温相似材料来模拟岩体及断夹层力学参数在工程长期运行中逐步降低的演化过程。总结出了新技术和方法并结合工程实例,用强度储备与超载相结合的方法,探讨论了拱坝坝肩失稳的破坏过程,破坏机理和破坏形态,得出了综合稳定安全度,提出了坝肩需要加固处理的具体措施和建议,为工程设计和施工提供了参考依据。 Based on making the experiments of a geological mechanics model withythree dimensions for stability of an arch abutment and refering theyconcept of intensity reserve,authors present a new technique and methodyfor simulating the step-by-step decreasing process in mechnicalyparameters of rock formation and the formation with fragment duringlong running term of a project by using the similar material withychangeable temperature. Moreover, selecting a project as an example andyusing the method in combination of intensity reserve with exceesiveycharge of the project. Authors explore the process,mechanism andyconfiguration of the disintegration of the abutment. In order to give the reference in design and construction of the project, a safety degree index of comprehensive stability has been suggested andyconcrete measures and proposals for the stability disposal of thyabutment have also been presented in this paper.
