Abstract: Effective boundary conditions to the Ginzburg-Landau equations at the twinning plane of an orthorhombic $(d+s)$ superconductor are obtained on the basis of microscopic BCS theory. The range of the parameters of orthorhombic strain is found where the order parameter behaves variously on both sides of the twinning boundary.
