The tunnel anchor scheme of rope hoisting system of the Shenxigou Bridge was put forward,and the structure design and calculation of tunnel anchors were given out.

Meanwhile,successful application of anchor pile further reduces the cost of this construction,and it is most convenient for the construction in the abrupt valley,which not only protects ecological environment and facilitates the transportation of construction material,but also serves as guidance for constructing long-span arch bri.

Design and construction of the earth anchored cable-stayed bridge;

This paper expounds the aseismic mechanism by introducing the aseismic design measurements concerning mid span joint,vibration segregation for crosswise displacement limit of the mainbeam at the towers,reasonable disposition of prestressed bundles and reinforce bars,partial design of earth anchored cable stayed bridges with lo.

According to the theory of flexibility method and the characteristic of earth anchored cable-stayed squeduct with a hang beam, the equation of deformation compatibility is established.

Since the commencement of excavation, the outside monitoring and internal anchorage tunnel observation have been conducted.
