Application and Mechanism to Support Tunnel Adjoining with Soft Rock Masses by Yielding Inverted Arch of Composite Structures
A yielding inverted arch of composite structures is designed to control serious floor heave of tunnel. Constitution of the inverted arch is studied to present mechanism of the composite structure to restrain floor heave. By field trial of the yielding inverted arch with composite structures, it is an effective method to control floor heave, and its important function is to absorb main elastic deformation coming from bottom strata.
