针对修建在岩基上的某泄洪洞预应力工作闸门室，采用有限元计算方法，结合有限元分析软件ANSYS进行三维有限元计算。研究工作闸门室在混凝土与岩体粘结和分离两种边界条件下的应力分布，分析在分离情况下对闸门室造成的影响。计算结果表明在不同边界条件下，预应力工作闸门室应力分布的区别主要集中在闸门室上游面和压力进水口段，分离情况对闸门室造成的影响较大。研究成果可以为工作闸门室的设计和施工提供参考。

Aimed at the prestressed work gate chamber of a spillway tunnel built on batholith ,the paper took finite element computer method and combined finite element analysis software ANSYS to carry out three -di-mensional finite element calculation .It studied the stress distribution of gate chamber under two different boundary conditions of bonding and separating of concrete and rock mass, and analyzed the effect on the gate chamber under the condition of separation .Calculation results show that the difference of stress distribution in prestressed work gate chamber are mainly concentrated on upstream face and pressure inlet section of gate chamber under different boundary conditions .The effect of separation on the gate chamber is greater .The result can provide reference for the design and construction of work gate chamber .
