摘要:
通过建立泸定大渡河大桥隧道锚三维实体模型,模拟隧道锚的开挖支护施工过程,分析了隧洞开挖支护过程中的应力、变形和塑性破坏区分布特性,在此基础上开展了支护作用、设计拉力等参数的影响研究。通过上述研究,基本掌握了隧道锚整个施工过程的结构受力特性,得出了隧道锚的推荐承载力,同时结合计算结果对施工方案提出了建议,以期提高施工安全。
Abstract:
This paper established the three dimensional solid modeling for the tunnel anchorage of Luding Dadu River Bridge. By simulation of construction stages of tunnel anchorage excavation and lateral support, the distribution characteristics of stress, deformation and plastic failure zone in the process of tunnel excavation support are analyzed. On this basis, the influences of parameters such as support function and design tensile force are studied. Through the aforementioned studies, the structural behaviors and stress characteristics of the whole construction process of tunnel anchorage are basically mastered, and the recommended bearing capacity of tunnel anchorage is obtained. In the meantime, considering the calculation results, some suggestions are put forward for the construction proposal in order to improve the construction safety.
