摘　　要：本文对圆板大挠度问题证明了与中面拉伸余能相关的一个余能驻值原理。并根据该原理提出一种两步变分解法以求解圆薄板卡门大挠度问题。文中的算例说明该方法是令人满意的。This paper prove a variational principle middle plane tension complementary energy for problems of large defection for thin circle plate. A two-step variational method is presented follows ofterwards. The method is used to solve problem of Von Karman's for large defection. Examplas showed that solution of satisfaction is obtained.
