摘　　要：在扭面特点分析的基础上,用矢量法推求出扭面的参数方程,同时针对传统土方量计算方法的不足,给出了原地形为扭面时的土方量精确计算公式,并对该公式的应用及误差分析进行了实例说明。结果表明,该公式误差小,计算精度高,适应面广。Based on the analysis of features of twist surface, parametric equation of twist surface was creatively derived by using vector law, At the same time, aiming at the deficiency of traditional earthwork calculation, an accurate formula for the calculation of earthwork with original twist surface was provided, also, this paper demonstrated the application of this formula and error analysis. The result indicates that it is of little error, high accuracy and universal application.
