Calculation method of bearing capacity of compound tunnel anchorage system of suspension bridge;

Based on field test results for compound tunnel anchorage system (tunnel anchorage & prestressed anchorage cable) of suspension bridge, the failure model and failure condition are analyzed.

The mechanical behavior characteristics,stabilization state of surrounding rock,deformation mechanism of anchorage,topology effect of tunnel anchorage system of suspension bridge were studied based on numerical simulation method.

Based on numerical simulation results of tunnel anchorage system for suspension bridge,and through validating by similar model field test,the mechanical behavior characteristics,deformation mechanism and stabilization state of rock mass of anchorage system have been researched.

The tunnel anchorage system is an anchorage style which.

Numerical simulation on scheme comparison between two concrete-plug lengths of west tunnel-type anchorage of Balinghe Suspension Bridge;

Compared with the gravity anchorage, the application of the tunnel-type anchorage can significantly reduce the engineering cost, yet the construction of the anchorage is difficult and involves quite a lot of technical challenges.

Recently, The tunnel-type anchorage was used widely.
