摘要
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。
The water flow behavior in cracks of cementitious materials is investigated experimentally through a permeation device designed by the authors. Fracture surfaces with different roughness are fabricated firstly and then permeation tests are performed on these surfaces with different crack opening widths. On the basis of the recorded flow rates the influence of surface roughness and crack opening width on the flow behavior of water is discussed. Furthermore, repetitive flow tests are performed for one fracture surface with one opening width and the transient flow behavior is studied by the experimental results.
