Focused on fast construct in underground structure,a new connecting type of precast RC beam-column joint is proposed,and mechanical properties of the joint are researched by full scale test. The results showed that the connection of the beam-column joint has a high assembling ability,a reliable connection and a high bearing capacity; it can satisfy the strength requirement of the force transmission in underground precast structure. Enough hoop reinforcement in joint zone can ensure the sheer capability of the joint.
