型钢混凝土地下综合管廊受力性能试验研究

Experimental Researchon Mechanics of Steel Concrete Underground Comprehensive Pipe Corridor

项目通过制作1∶5缩尺模型,计算运营过程中城市地下综合管廊的受力情况,通过静力加载试验对试验模型进行加载,探讨这种结构受力作用下的裂缝开展、破坏过程和模式,分析结构的力学特性,揭示结构的传力机理,并从强度、刚度、延性和耗能等方面对型钢混凝土框架结构做定量分析,得知其变化规律和相应的参数。研究结果可以为型钢混凝土框架结构力学设计和非线性有限元分析提供试验支撑和数据。

By making a 1∶5 scale model,the project calculates the stress of urban underground comprehensive pipeline corridor in the course of operation,loads the test model through static loading test,discusses the crack development,failure process and mode under the force of this structure,analyses the mechanical characteristics of the structure,reveals the mechanism of force transmission of the structure,and from the aspects of strength,stiffness,ductility and energy dissipation.The steel reinforced concrete frame structure is analyzed quantitatively,and its variation law and corresponding parameters arekNown.The research results can provide experimental support and data for mechanical design and non-linear finite element analysis of steel reinforced concrete frame structures.
