Abstract: A multi-dimensional space load and fire test system for a tunnel structure, which includes a multi-point loading self-balancing reaction force system having a rigid platform, two furnace body side-sealing apparatuses (22) and a model assembly and transport apparatus (23) for transporting and situating a tunnel model are on a track on the rigid platform (9), the two furnace body side-sealing apparatuses (22) are respectively used for sealing two end openings of the tunnel model, a tower-type combustion vehicle can be placed within an inner cavity of the tunnel model, a plurality of sets of evenly distributed self-adaptive loading apparatuses (3) used for exerting loading forces on an outer wall of the tunnel model are connected between two reaction force frames (1) of the multi-point loading self-balancing reaction force system. The present system is able to perform loading on tunnel models having different cross section shapes, can be adapted to testing requirements of tunnel structures having different cross section shapes, and with respect to tunnel structure fire testing in particular, a camera of the present system has a large imaging angle of view, the present invention has good heat resistance, possesses both terminal imaging and distance measurement, and can amply satisfy a use requirement for the high temperature environment of a tunnel fire.
