Assessment of mechanical characteristic for reinforced concrete precast arc shaft lining is achieved by experiment and finite element analysis. The finite element results agree well with measurements from laboratory, which validate the calculation model. At the same time, the load carrying capacity of the high strength reinforced concrete precast arc shaft lining is very high. The factors which influence its load carrying capacity are, in turn, the ultimate uniaxial compressive strength of concrete, the ratio of the thickness to the radius and the ratio of the reinforcement to the concrete. Under the load of uniformity, with the strength grade of concrete increases 10 MPa, its load carrying capacity raises 1.26 MPa. The ratio of the thickness to the radius increases 1% , its load carrying capacity raises 0.85 MPa. However,when the ratio of the reinforcement to the concrete is enlarged 3 times, its load carrying capacity increases only 0.1 MPa. Therefore for designing the high and strong reinforced concrete precast arc shaft lining, the ratio of the reinforcement to the concrete needs only to be considered from the structural point of view rather than improving the load carrying capacity.
