结合隧道结构的振动台模型试验研究,对隧道衬砌模筑混凝土的相似材料进行了试验,选用石膏、重晶石粉和石英砂为模拟材料,通过大量的室内试验研究了不同配合比下材料的力学性能,找到了合适的配合比;同时研究了不同的养护方式对试件强度的影响规律;最后得到的试验结果与隧道震害基本一致,验证了相似材料配合比的正确性。
Based on the shaking table model test of tunnel structure, similar materials of concrete for tunnel lining construction were tested. Using gypsum, barite powder and quartz sand as simulation materials, the mechanical properties of materials under different mixture ratios were studied through a large number of laboratory tests And find out the suitable compounding ratio. At the same time, the influence of different curing methods on the strength of the test piece is studied. The test results obtained are basically the same as the tunnel damage, which verifies the correctness of the mixing ratio of similar materials.
