摘　　要：吉林省中部城市引松供水工程局部覆土深度较浅,成洞条件极差。衔接该段建筑物的隧洞洞径5.1 m,内水压力0.5～0.55 MPa,设计采用内圆外城门洞型式的无粘结预应力圆涵。文中通过有限元计算,验证设计的安全性、合理性。The conditions of tunnel formation is very poor because of the relative shallow depth of the local overburden layer for the water supply project from the second Songhuajiang river to the central cities of Jilin province. The diameter of tunnel linking the structures is 5.1m and the inner water pressure is 0.5～0.55Mpa, the design of unbonded prestressed circle culvert is adopted with the type of inner circle and outer arched section. Through the calculation of finite element, the security and rationality of the design is verified.
