| Abstract: |
| As the transition section to link with different cross sections,the changeover form is widely used in water distribution-building project,but it doesn't have a united scientific calculational method in calculation of earthwork at present.Therefore,this paper here lists several changeover forms commonly used in project.Based on the analysis of its mathematics characteristics of cross section function,by applying calculus integral theory,a general calculation formula of physical volume of the changeover form will be obtained,characterized by simpler calculation,fewer error,and clearer concept.Thus this new formula will provide the designers with great help in engineering practice. |
