[提要]  预应力双曲抛物面索网因其几何非线性而使精确求解困难。作者将配线法与Galerkin法结合使用计算该类具有复杂底平面的索网结构。该方法考虑索网结构特点配线，同时以基函数为权函数提高分析精度。与其它加权残数法比较，该方法简便实用而较适于索网结构。算例表明结果可靠。

Collocation line-Galerkin method of weighted residuals is employed to analyse hyperboloid cable network structure with complicated basal plane. In consideration of characteristic of the structures, as weighting function the basis function is adopted in the collocation line method. The approximate fomula is simple and efficient in comparision with the results computed by other method of weighted residuals.
