| 摘 要： | 糯扎渡水电站导流隧洞采用有限元对施工期隧洞围岩稳定进行分析,提出一次支护设计参数,并利用三维非线性反演分析一次支护设计的可靠性,作为施工过程调整支护措施的参考依据。隧洞混凝土结构衬砌设计主要对内、外水荷载作用的合理取值进行分析,结合施工期围岩稳定分析,采用平面有限元对结构力学法计算结果进行了复核,设计科学、合理。

| Abstract: | The stabilization condition of diversion tunnel adjacent rock during construction period is analysed in finite element method,Design parameters of the fist support is presented.The reliability of the fist support is gotten in three-dimensional nonlinear finite element inversion analysis method,It is dependence to adjust support during the construction period.Main work is access rational inward-outward water pressure to calculate during diversion tunnel concrete structural design,and combine the analysis of diversion tunnel adjacent rock stability,the result of structural mechanics method is checked by planar finite element method.So the design is scientific and rational. |
