摘　　要：研究了大型塑料检查井流槽式汇合三通井座在回填土下曳力、垂直土压力、井座侧向土压力等永久载荷和车辆荷载多耦合力作用下的应力应变,仿真结果显示在多耦合力作用下,井座支管处应力应变较大,存在失效的风险。为了提高大型塑料检查井流槽式汇合三通井座的刚强度,提出了环向加强筋、纵向加强筋和网格加强筋三种加强筋方案,并对比分析了在不同加强筋配置时井座的刚强度情况,结果表明:网格加强筋和环向加强筋对井座的刚强度提高效果明显,为流槽式汇合三通井座的结构优化设计提供了参考。This paper investigates the stress-strain behavior of a plastic manhole flow trough confluence tee seat under the combined action of permanent loads such as drag force,vertical soil pressure and lateral soil pressure,as well as dynamic loads from traffic.The simulation results indicate that under the influence of multi-loads,the stress and strain at the branch of the well seat are relatively high,posing a risk of failure.To enhance its structural strength,the paper proposes circumferential reinforcement、grid reinforcement、longitudinal reinforcement three reinforcement schemes and compares the stiffness of the well seat under different reinforcement configurations.The results show that the grid reinforcement and circumferential reinforcement significantly enhance the stiffness of the well seat,providing a reference for the structural optimization design of the flow trough confluence tee seat.
