摘　　要：根据映射原理将排水子结构内的无序节点编号映射为节点凝聚所需的特殊编号,按映射后的节点编号进行节点凝聚并形成子结构的渗透矩阵,然后根据逆映射原理将渗透矩阵和渗透方程右端项逆向映射为原子结构的渗透矩阵和右端项,实现原排水子结构的节点凝聚以及总体渗透矩阵和右端项的组装。方法实现简单,效率高,可应用于其他类型子结构的节点凝聚中。According to mapping theory, the non-ordered node numbers of drainage substructure are mapped into special ordered node numbers. Then, the eoacervation degrees of freedom for inner nodes in drainage substructure is achieved, and the seepage matrix and right-hand-side vectors of seepage equations based on these special node numbers are obtained. After that, the matrix and right-hand-side vectors are inversely mapped into the original actual drainage substructure, which can be finally used to form the seepage matrix and right-hand-side vectors of overall system of equations, Application shows that this method is efficient and can be easily realized. In addition, it can be applied to other kinds of substructures.
