摘　　要：推导了平面预应力索网变形曲面的偏微分方程,给出了匀布荷载、匀布拉力下不考虑几何非线性的一种级数解;通过改变变形后索拉力得到了考虑索网结构大变形几何非线性影响的迭代求解法;通过工程实例验证了级数解迭代法计算索网变形和索拉力大小的准确性。所给出的级数解迭代方法收敛快、误差小,便于在工程中应用。The differential equation of the deformed surface cable net structure is deduced. A kind of series solution of the differential equation is provided not considering geometry non linearity. The iterative method is given considering the geometry nonlinearity. The accuracy of the progression iterative method to calculate the deformation and the cable force is confirmed by the design of an engineering example. The method has the extremely accurate result. The method is easy to hewe application in engineering.
