摘　　要：采用三维线弹性有限元法 ,研究了小浪底水利枢纽孔板洞中闸室段在内压和外压作用下围岩、衬砌混凝土的应力和变位。通过对比分析 ,找出了结构设计的控制条件 。With the measure of three dimension linear and elastic finite element,the stress and displacement of surrounding rock and lined concrete at the section of mid gate chamber of orifice tunnels of Xiaolangdi multipurpose dam project was analysed under the conditions of inner and outer pressure.Through contrast analysis,the control conditions of structural design were found out and a thorough assessment was made on the influence to the structure by the existing vent holes and monolithic structural stability of mid gate chamber.
