In this paper fictious loads are applied to a special auxiliary boundary for solving plate bending problems by indirect BEM. The element on the auxiliary boundary is parallel to , and has the same length as, the corresponding element on the original boundary. Since it is usually discontinuous, it is called intermittent auxiliary boundary. By this method improper integrals are avoided and accuracy is improved.

This paper dealt with the method of calculations for stress intensity factors caused by multiple-cracks in a concrete structure of hydraulic engineering. The concept and program of fracture mechanics was employed. According to the concept of "released stress" and modifying the Cauchy's singular integral equations, a Fredholm integral cquation system was obtained. Based on the consideration of interactions between the cracks and boundaries, the fictitious loading method was suggested. Finally, the S.I.F. and stress analysis could be finished. The judgement of the crack which was the most dangerous can also be solved. The cwperiments for the specimen with multiple-cracks were performed. The results showed good agreement with the calculation.
