Mechanical Properties Test on the Basic Components of New High Strength Arches,ory and numerical tests of axial compression is carried out on the components in this chapter. The analysis is made on the deformation and failure mechanism and bearing mechanism of the basic component, and the mechanical properties of the components are studied as well. Research is carried out on t

cathartic

Calculation Theory of the New High Strength Arch, the confined concrete arches in roadways. This chapter first establishes the calculation and analysis model for the casing joint of the arch, and analyzes the action mode and mechanical properties of the casing joint. The calculation formulas of internal force are derived for arbitrary section numb

Halfhearted

Experimental Study on the Bearing Mechanism of New High Strength Arches,rch comparison tests are carried out; the deformation and the strain are obtained in the experiment process of the arches; and the arch bearing mechanism is clarified with different cross-section forms and shapes, and different load modes. The test results have verified the correctness of theoretica
