Analysis on installation of bridge’s main arch using MSC Adams virtual prototype;

The span of the main arch is 103m and the span of the minor arch is 21m.

The striding road bridge is the main arch.

Construction technology with support of the long span main arch ring of the reinforced concrete arch bridge;

Demolishing scheme of main arch ring in deck-type reinforced concrete trussed arch bridge;

For the old road widening and rebuilding discussion is made on the design and the construction technology of stone arch bridge especially in its foundation, main arch ring, roadway pavement, sidewall and fills.

control measure before concrete pumping of main arch rib.

The main bridge of the Shengmi Bridge in Nanchang is a concrete-filled steel tube multi-arch bridge with two main spans each 228 m in length, whose main arch ribs are erected for the first time in China by integral lifting method with giant gantry.

Here we have an analysis on stability of Xinguang bridge by taking the middle arch rib of the bridge as object to be studied through three-dimension finite element program, and elaborate the contribution of cross stay style and space, main arch rib to the stability of arch rib.

Some diseases were presented in the main arch circle and the architecture above the arch of Wanche ArchBridge.

Based on Coulomb’s earth pressure theory,assuming the trace of the principal stress arching in the back of rigid retaining wall as parabola,the theory formulae are obtained including the lateral coefficients of active and passive earth pressures and the friction coefficients of horizontal differential elements;then improved formulae of active and passive earth pressures are presented.
