通过三维模型光弹性试验,研究了短壳槽身的应力状态。得到了分别在自重、半槽水、设计水、满槽水荷载及在自重与上述几种荷载共同作用下槽壳、端肋、横杆上的表面应力以及在设计水荷载下端肋的主拉应力轨迹线和在设计水与自重共同作用下槽壳表面的主拉应力等值线图详细结果。 Through the three-dimensional model photoelastic test, the stress state of short shell body is studied. Respectively, under the weight, half tank water, design water, full tank water load and under the combined weight of the load with the above several under the shell, end rib, surface stress on the bar and in the design of water under the load of the end of the main rib pull Stress trajectories and the detailed results of the principal tensile stress contours of the shell surface under the combined effect of design water and self-weight.
