渗流场反分析的一种新的数学解法

A new method for the back analysis of seepage problem

本文提出了渗流场反分析的新解法．建议把水头函数展为台劳级数，并略去高阶项，每次选代中，只需求解传导矩阵１次，其余都是简单的回代计算．这样计算效率有很大提高．同时还建议利用子结构法，能进一步提高计算效率．

A new method is proposed for the back analysis of seepage problem.The head function ac is expanded into taylo/s series and the terms with order higher than second is neglected since only one matrix must be solved in each step of iteration the computation speed is accelerated.Meanwhile the ulfilization of substructure method is suggested to further promote the computation efficiency.
