A new waveguide made of changing a wide wall of a rectangular waveguide to a uniform curved wall is called conformal waveguide. a kind of expression of approximate solution for domain mode of the new waveguide, including symmetric, unsymmetric arc, parabolic arch, hyperbolic arch, elliptic arch, etc., is constructed by using boundary condition of mental waveguide, variational method and boundary element method. by using the equivalence principle, an approximate calculating formula for equivalent resonant conductance of a narrow longitudinal halfwavelength slot cut in the curved wall of the unsymmetric arcrectangular waveguide is derived, and the result is shown. although this solution is approximate, it can solve the problem in designing the slotted antenna of such conformal waveguide

分析得出，隨著側壓力系數的增大，主應力量值減小，主應力方位難改變；隨著與斷層走向的夾角增大，主應力量值增大，應力方向難改變：隨著巖石的彈性模量的增大，主應力量值增大，方向變化越大；隨著泊松比的增大，主應力量值減小，方位變化越大。隨著側壓力系數的增大，頂、底拱處的各應力值增大，拱腰處的主應力減小，剪應力增大，側拱處的各主應力減小，同一側壓力系數的條件下圍巖質量越差，各應力值也越小；隨著洞室埋深的增加，圍巖壓力也增大，圍巖質量越差，其應力值也減小。 -
