Taking into account that the pre-stress of the anchor affects pre-reinforcement of the soil mass,the paper discusses the distribution of pre-reinforcement force of the soil mass.

This text introduced the variety techniques of reinforce,and combine example of engineering emphasize to discussed the characteristics of the method of reinforced by Enlarge section and the method of reinforced by prestressing tendon.

Fracture mechanics analysis of prestressed consolidation technology used to spandrel gravity dam;
