| Outline of Final Research Achievements |
In the existing buried pipe seismic design guidelines, the restraint force acting on the pipe is set to the same value. However, it is considered that the restraint force acting on the pipe shows different values at each position. Therefore, in this study, the authors measured the earth pressure acting on the surface of the buried pipe by performing the buried pipe horizontal traction experiment and the numerical analysis of this experiment was carried out in order to confirm the results of this experiment. As a result, it is clarified that both the horizontal component and the vertical component of the earth pressure value acting on the pipe surface are larger in the lower half than the upper half of the pipe.
