| 摘 要： | 海底管道铺设是近海工程建设中的重要环节．由于铺管问题的控制方程具有较强的非线性，加之边界可动，所以问题的求解比较困难．本文采用奇异摄动法较好地解决了这一问题，并与有限元解作了比较．

| Abstract: | Pipelaying is an important operation in offshore engineering. As its governing equation is nonlinear and the boundary is moveable, the ana- lytical solution is difficult to get. In this paper, a singular perturbation method is used to solve this problem. The comparison with FEM shows a good agreement. |

| Keywords: | pipelaying geometric nonlinearity sin- gular perturbation method |
