该文对水泥基材料裂隙中水的流动规律进行了试验研究,试验首先制备了具有不同粗糙度的水泥基材料断裂表面,然后通过自行设计的水泥基材料裂隙渗流装置,完成了对不同水泥基断裂面在不同裂隙宽度下的渗流试验,根据试验结果分析了水泥基材料断裂面粗糙度和裂隙宽度对水流量的影响;通过对同一断裂面和同一裂隙宽度的原位重复性渗流试验讨论了裂隙间水的非稳态流动特征。 In this paper, the water flow in the cracks of cement-based materials was experimentally studied. Firstly, the fractured surfaces of cement-based materials with different roughness were prepared. Then the fractured seepage devices of cement-based materials were designed, According to the test results, the influence of roughness and crack width on the water flow of cement-based material is analyzed. Through the in situ repeated seepage test on the same fracture surface and the same crack width, Unsteady flow characteristics of water between fractures.
