摘要
对混凝土衬砌支护结构进行受力分析,利用混凝土等效弹性系数模式下的本构关系,采用有限元计算程序ADINA进行模拟分析,得出了当采用三心拱形支护结构时,在侧压力系数λ由小到大变化过程中,二次衬砌的承载力变化情况。
Based on stress analysis of the concrete secondary lining structure and the constitutive relation of concrete equivalent linear elastic model,using ADINA to simulate and analyze.Draw a conclusion that bearing capacity change regularity of lateral pressure coefficient from small to big using three-centered arch retaining structure.
