摘要
根据岩体地质力学模型试验的特点,研制出一种新型组合式三维地质力学模型试验台架装置。该装置主要由台架体和台架底盘组成,其中台架体由盒式铸钢构件通过高强度螺栓连接组合而成,台架底盘由带有螺栓槽的型钢钢板并列拼接而成。通过底盘高强螺栓可将台架体与台架底盘在所要求的螺栓槽位固定,形成组合式三维地质力学模型试验台架装置。该装置在一大型分岔隧道三维地质力学模型试验中的具体应用结果表明,其具有结构新颖、刚度大、整体稳定性好、组装灵活方便、尺寸可任意调整并能满足不同规模模型试验要求的显著技术优势。
According to the feature of geomechanical model test of rock mass,a new type combination 3D model test rack apparatus which is composed of rack body and rack bottom plate,is researched and manufactured.The rack body of the apparatus consists of various box type steel structure members connected by screw bolts with high strength;the rack bottom plate consists of shape steel plates with screw bolt grooves.The 3D combined geomechanical model test rack apparatus is formed by fixing rack body and rack bottom plate in the screw bolt groove through high strength screw bolts.Application of the apparatus to a large-scale offspur tunnel model test indicates that it possesses some remarkable technical superiorities such as original structure,great stiffness,good stability,flexible assembly and free regulation for its size.
