摘　　要：为研究装配式钢筋混凝土建筑接缝渗漏机理,以及风力与缝宽对渗漏的影响,运用毛细动力学原理,以假定无限长的毛细缝渗水为模型,对缝隙中水受力关系进行分析并推导了毛细缝的吸水动力学方程式。在此基础上,还分别研究了风压与缝宽对渗水快慢的影响,并与试验结果进行了对比。研究结果表明:接缝渗漏深度随渗漏时间、裂缝宽度和风压增大而增大。In order to study the joint leakage mechanism of prefabricated reinforced concrete buildings and the influence of wind force and joint width on leakage,the capillary dynamics principle is used to analyze the water stress relationship in the gap with the assumption of infinite capillary joint seepage as the model,and the water absorption dynamics equation of the capillary joint is derived.On the basis of the equation,the influences of wind pressure and seam width on the speed of water seepage are studied respectively,and the results are compared with the test results.The results show that the joint leakage depth increases with the increase of leakage time,crack width and wind pressure.
