Based on the in-depth analysis and study of the cutting mechanism of the cutterhead of the composite EPB shield ma-chine, the calculation model of cutterhead load is established, and the corresponding calculation formulas are deduced. Compared with the data logged from engineering projects, the calculation results can meet the requirements of the practical engineering. The formulas can serve as a reference for cutterhead load calculation.%通过对复合型土压平衡盾构掘进机刀盘切削机理深入分析与研究，建立刀盘载荷计算模型，得出相应计算表达式。通过与工程实测数据的对比表明，计算结果能满足工程要求，可供盾构刀盘载荷计算参考。
