采用断面法研究了坡改梯工程中田面设计参数与土方工程量的关系，采用灰色模型对典型田块参数进行了优化设计.结果表明：随着田块坡度的不断增大，田坎高度也随之增大，并且田坎高度以小于4.5 m为宜；田面宽度、田坎高度、田坎倾角、田面坡度是影响土方工程量的决定因素，其中，田面宽度的设计应控制在10~40 m 之间，田面宽度过小则田坎占地宽过大，经济效益不高，也不适宜机械操作；随着田面坡度的不断增大，最小土方工程量也在不断增大.

The relationship between earthwork and design parameters of field in level terrace construc-tion are researched with section method,the degdesign parameters of field are optimized with gray multi-obj ective programme.The result shows that with the field slope increasing,the height of terrace ridge is in-creasing also.The suitable errace ridge heigth should be under 4.5 m.The terrace width,ridge heigth,ridge angle and slope are the key factors to earthwork volume.The proper terrace width should be controlled within 10~ 40 m.If the terrace width is too narrow,the proportion of ridge floor area would be high.That will cause lower economical benefit,and unfit for machine working.The minimum earthwork and its rela-tion to terrace width,ridge height,ridge angle and slope are calculated in the paper.
