1. A deepwater platform welded joint testing system, comprising:
a host unit, a hydraulic unit and a control unit, wherein the control unit is connected with the host unit and the hydraulic unit respectively;
the host unit comprises a bearing frame placed on a bearing base, biaxial tension/compression loading oil cylinders mounted on the bearing frame, a lateral force resistant mechanism connected to the front ends of the biaxial tension/compression loading oil cylinders, counter-force supports fixed to the top end of the bearing frame and biaxial bending loading oil cylinders mounted on the counter-force supports;
the lateral force resistant mechanism comprises a bearing support connected to the front ends of the biaxial tension/compression loading oil cylinders, a rolling row mounted on the bearing support and a mounting plate mounted on the rolling row;
the biaxial tension/compression loading oil cylinders are four biaxial oil cylinders, are vertically arranged, and have multi-axial tension/compression loading capacities such as uniaxial tension/compression and biaxial tension/compression;
the biaxial bending loading oil cylinders are two biaxial oil cylinders, are vertically arranged, and have multi-axial bending loading capacities such as uniaxial bending and biaxial bending; and
the biaxial tension/compression loading oil cylinders and the biaxial bending loading oil cylinders have a combined capacity, and the system has a uniaxial/biaxial tension/compression and bending composite loading capacity.
