Lunar surface landing platform structure

The invention provides a lunar surface landing platform structure which can be suitable for installing and bearing four large-capacity spherical storage tanks and a large-capacity passenger compartment, and the requirements that four variable thrust engine combinations are installed in the middle and four landing legs are evenly distributed in the circumferential direction are met. According to the lunar surface landing platform structure, the means of spherical arch installation of the spherical storage box, main bearing of multiple force transmission paths completed by the partition plates at the same time, tangential installation of the end frame of the passenger compartment and the like are comprehensively adopted, the structure weight is greatly reduced, and the bearing ratio of the manned spacecraft structure is 5-6%; the lunar surface landing platform structure provides a large-area load and equipment installation area, particularly provides a large-area heat dissipation area and an expandable heat dis
