摘要：
The bridge and tunnel connecting works are a complex combination of the bridge structure and the tunnel structure and its surrounding rock, rock & soil mass of inverted slopes and protection works adjacent to the entrance. The mechanical behavior and damage mechanism of various parts of the bridge and tunnel structures and their surrounding rock & soil mass are closely related with factors such as the types of structures and foundations, relative location, terrain and geology conditions, external loads and so on. In view of the current situations that comparatively less investigations have been done into such special engineering work at home and abroad, the method to carry out indoor model tests of multiple-source damages to bridge and tunnel connecting works in surrounding rock Grades IV and V was explored with respect to practical engineering examples. The results are achieved as follows: The relationships of the physical quantities of the structures and parts of the bridge, tunnel and surrounding rock & goil mass are analyzed with the dimensional analysis method according to the similarity theorem and in consideration of the characteristics of the bridge and tunnel connecting works the similarity criterions and constants are derived; the similarity raties of the models of bridge and tunnel structures and the mix ratios of the similar materials of surrounding rock are determined, and material tests are conducted. The introduced model test platform and test methods provide reference for model tests of the same kind.
