| Abstract: | The difference between the top of the free surface of the groundwater and under it during the process of the Finite Element Analysis is point out, and the compound element method to solve the constant strain intersection element is put forward in this paper. Taking tetrahedron as an example, the principle of the compound element method, and solving method of coefficient matrix, solving formulas of volume integration and curved surface integration in the compound element are introduced detailed. |
