The invention belongs to the technical field of spacecraft structures, and particularly relates to a main load-bearing structure of a large-breadth high-resolution optical remote sensing satellite. The problems that a main load-bearing structure of an existing large-breadth high-resolution optical remote sensing satellite is large in component part number, large in structural weight proportion, large in whole satellite envelope, large in rotational inertia, complex in assembly process, not beneficial to batch production and assembly, low in emission networking efficiency and the like are solved. The main force bearing structure comprises a bottom loading plate, a middle-section force bearing cylinder and an upper-section force bearing cylinder; two sides of the bottom loading plate are respectively used for installing a large-width high-resolution camera and electronic equipment, and the bottom loading plate is provided with a first type of external mechanical interface; the two sides of the outer portion of the middle section force bearing cylinder are used for installing sailboards, and the middle section force bearing cylinder is provided with a second type of external mechanical connector. And the outer side of the top of the upper-section bearing cylinder is used for mounting electronic equipment. The main load-bearing structure is used for guaranteeing the integrity of the satellite configuration.
