| Abstract: | In view of the deficiency of the existing calculation methods for the earthwork of distortion surface of the channel and based on MATLAB,a new calculation method is put forward,which applies the second polynomial to fit the sectional area function,and uses the Romberg integration formula to calculate the earthwork of distortion surface of the channel.The calculation results indicate that this method is simple,precise and may provide references for designers. |
