Relation between the size of plastic zone and the location of the peak value of axial force distribution in fully bounded rock bolt has been analyzed with in situ measurements and a computer simulation.

Mechanical analysis on full length bolt supporting;

The horizontal stiffness coefficient values of rock anchor under different conditions are obtained through using numerical method to simulate the pullout test of the fully-grouted rock anchor.

In the structure design of the people s Stadium of Dalian City, the rock anchor foundation is adopted to solve the problem about permanent anti-floating stability in the big size underground construction according to the local conditions.

By discussing on the differeces of design for rock anchorage bar between in China and abroad,it is concluded that the different designing results from the dissimilarity of detecting means.
