摘　　要：水利工程输水隧洞一般埋深较大、洞径小,施工支洞布置困难,TBM工作面独头掘进长度相对较大,施工通风设计往往成为施工布置的一个关键因素,分析了长距离输水隧洞TBM施工通风计算主要参数和公式,结合MathCAD软件特点,编制通风计算程序,并通过具体案例分步骤计算并验证程序的可行性。The convey tunnel of hydraulic engineering generally has large buried depth and small hole diameter, and it is difficult to arrange the access adit. The single heading length of TBM working face is relatively large, and the construction ventilation design is often a key factor in the construction layout.Analyzes the main parameters and formulas of TBM construction ventilation calculation for long-distance convey tunnel. Combined with the characteristics of MathCAD software, the ventilation calculation program is compiled, and the feasibility of the program is verified by step calculation through specific cases.
