This paper introduced the basic principle to acquire height anomaly using orthogonal function,took the control surveying results of Hufengling section of Suiman road in Heilongjiang to testify,and drew specific conclusions which is valuable to direct engineering height surveying.

Using the orthogonal function system mixed a weight function as the basis function,the drawback of forming an ill-conditioned system of equations for the moving least-square approximation method is overcome.

Based on the quadrilateral plate incompatible element,the quadrilateral plate compatible element was constructed with the method of the adhesive correction function and an expression of element stiffness matrix was derivated,which is used in a caculation for a plate supported from the plate s four sides under the distribute and concentrated load.

Based on the optimal uniform approximation method and the least square approximation method, first order, second order and third order polynomials are presented to approximate the correction function of Log-MAP algorithm, and the approximation precision is compared between the algorithms.
