To determine the distribution of the effective stress of the prestressing tendons in the oval sludge digester, the friction loss caused by the variable-angle heel and the duct friction coefficient are often required to be measured on site. Oval sludge digester of Zhangzhou water treatment plant is a　bidirection prestress structure without bond, circumferential prestress tendons are pretensioned　through OVM wandering anchor devices with the variable-angle heel. Contrasted with the normal prestressed concrete structure,some new features are included in this test. When measuring the friction loss,the value of elongation of the prestressing tendons is tested at the meantime.
Keywords: oval sludge digester; prestressed friction loss; variable-angle heel; value of elongation;  water treatment plant
