Prestress losing and Compensate Method in the Reinforcement Project of Retaining Wall

The feasibility of using the second compensate tension to solve the prestress-losing problem was analyzed with the methods of numerical analog calculation and experiment according to the reinforcement project of 104 National Road in Shandong Province. The result indicated that the reciprocity of the closer anchor and the prestress attenuation can be effectively eliminated using the second compensate tension. It is concluded that the problem of prestress-losing should be considered in the course of design and construction and be solved with the method of the second compensate tension in the soil reinforcement project of prestressed anchors.
