This paper describes analytical results by a boundary element method on interfacial stress singular conditions near the tip of shrinkage crack terminating at the interface between the concrete bodies and cemeticious adhesive mortar. A general stress function near the stress singular points is theoretically presented by a linear combination of the singular solutions of type r^<-λ>, the no singularity solutions and the particular solutions which are independent of distance r from the crack tip by a fracture mechanical method. A new method is presented to obtain the values of several kinds of singularity parameters. Furthermore, the usefulness of these methods and the characteristics of the three parameters under different influences of several kinds of finishing conditions are discussed.
