Shaking Table Experiments on Lightweight Thrust Restraint for Buried Bend
At a bend in a pressure pipeline, thrust force is generated according to the bending angle and the internal pressure. Generally a concrete block is installed at the bend to resist thrust force. However, it was reported that the concrete block could be one of weak points during an earthquake due to the inertia force of the concrete block. Therefore, in our previous study, the lightweight thrust restraint using geogrids has been proposed. In this study, shaking table tests were conducted in order to verify the safety of the lightweight thrust restraint in liquefied ground. From the results, it is found that the lateral movement of the bend with the proposed method was smaller than that with the concrete block.
