将数值流形方法应用于P型自适应分析，推导单元不同阶次的位移函数及其单元刚度矩阵表达式，引入了对应情况下的节理单元及其刚度矩阵。编制了计算程序，数值算例表明该算法可行。
The numerical manifold method is applied to the P-type adaptive analysis. The displacement function of different orders and the element stiffness matrix expression of the element are deduced. The corresponding joint element and its stiffness matrix are introduced. The calculation program is compiled. Numerical examples show that the algorithm is feasible.
