Introduction With the high development of the freeway [1], public engineering and some other infrastructures, the span of the bridge in our country is becoming larger and larger, as the deflection values of some bridges listed in table 1, we can see that the deflection is a critical problem at the mid span of the long-span bridges during the service time.

Using Finite Element Method to simulate and analysis the result,For in the engineering application of the sandwich type wall panel provides the basis.
Inner force regression coefficient curve Substitute the coefficient and constant that have regressed into the formula (1), at the same time substitute variables into the formula too, so that a new group of bending moment data can be worked out ,compare these new date with the Matlab data that were gotten from finite element analysis , the deviations of the checking results are all less than 5% ,so the formula has higher accuracy, so the formula of Mxmax finally is （3） The higher accuracy of the formula can meet the engineering application, so the formula has a better applicability.

Settlement and deformation are the main troubles in civil engineering.
As the engineering practice, a number of settlement calculation methods were developed.
Experience formulas and curve fitting method are not perfect in engineering practice, too.
It is a new attempt to apply neural networks theory to civil engineering.
