【Abstract】 The strengthening structure of grouted clamp provides technical support at home and abroad for underwater offshore platform jacket which have fragile nodes and the damaged structure. In order to ensure the safety and reliability of offshore platforms theoretical analysis of buckling was done with buckling theory under uniform axial compression and the finite element analysis software ANSYS for pipeline before and after the installation of grouted clamp. And it combined with experiments to verify the reinforcement effect of grouted clamp on the damaged pipe. Combination of theoretical and experiments has fully proved that the strengthening structure of grouted clamp is a simple and feasible reinforcement,it can solve the difficulties in offshore platforms currently at home faced by local strengthening technology on contact node of pipe and underwater steel bars.更多还原
