Load bearing conditions of the steep slope dam blocks are rather complicated during the construction and operation peroids and there are relatively large stress concentration areas.

Due to the limitation of terrain and culture on construction of expressways in mountainous areas,it is common to lay out lines on abrupt slope.

This paper introduces credible computing methods for discharge of starting ski jump and ending ski jump according to several cases such as abrupt slope,slope,zero slop and diffuser connecting to the front of nose of weir,which are compared with practical projects.
