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 () and a model assembly and transport apparatus () for transporting and situating a tunnel model are on a track on the rigid platform (), the two furnace body side-sealing apparatuses () 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 () used for exerting loading forces on an outer wall of the tunnel model are connected between two reaction force frames () 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.

Multi-dimensional space load and fire test system for tunnel structure, and method for implementing same

A multi-functional support capable of transferring a horizontal and multi-point local vertical load is provided. The multi-functional support is mainly formed by detachably assembling a distribution beam capable of transferring a vertical load locally and independently at multiple points, detachable upright columns, a template beam and a support base. The distribution beam capable of transferring a vertical load locally and independently at multiple points is located between tops of the two upright columns. The two upright columns are mounted on the support base. The template beam is located between the two upright columns, arranged on the support base and connected to the support base. The support base is fixed on a ground. The distribution beam capable of transferring a vertical load locally and independently at multiple points, the detachable upright columns, the support base and the template beam are located in the same plane. The multi-functional support can perform various experiments such as vertical loading, horizontal reciprocating loading and multi-point local independent vertical loading. By means of the detachable upright columns, loading and constraint fixing of an experimental wall can be realized step by step, thus reducing damage to a specimen by a moving specimen. The damage form of the loaded specimen can be kept effectively.
