Multicriteria analysis of a high-speed railway station area development project

<p>The main entrance of Chongqing West Railway Station adopts the non-landing compound arch with a span of 108m. In this paper, the nonlinear finite element theory is applied to analyze the bearing capacity and seismic ductility of the compound arch joints. Low frequency cyclic loading tests are performed on the 1/5 scale model. Based on the calculation and test results, a double beam structure and a section of steel truss are placed in the arch joints to bear the force of the arch. Moreover, the buckling-restrained brace (BRB) is placed in the lower part of the arch that enables most force directly transmit to the foundation of the arch. Unlike BRB’s common use as an inter-column support, it now acts as a buckling constraint support in the large earthquake. For instance, it can be yielded before the frame column to improve earthquake resistance. The research results indicate that the compound arch joint structure successfully accomplishes the seismic design goals of strong joints with weak component. Moreover, the study provides the theoretical basis and design reference for the application of BRB and long-span arch structures in high-speed railway station.</p>

Aggregate Concrete

Applied in the construction of Wuhan railway station of the Wuhan-Guangzhou high-speed railway, the super-lightweight aggregate pumping concrete has been developed by the independent study on the tackifier, the substitute of lightweight aggregate for sand and tackifier for sand. The concrete has been used for 58000m3. The dry bulk density of the lightweight aggregate concrete is controlled at 1160kg/m³. And the concrete has a good performance in the homogeneity and working condition, and is easy for pumping.
