The invention discloses a spatial
layout planning method for a
cascade silt arrester group. According to the method, the
debris flow energy regulation and control intensity F of the ladder dam group is decomposed into three indexes including the
dynamic energy dissipation rate, the
potential energy storage rate and the
total energy net loss ratio, a
mathematical model among the three indexes including the dam group relative
height difference Z and the F value is established, and the problem of overall
layout around the blocking function level in dam group planning is solved. According to the optimization method, spatial elevation parameters are introduced, and the problem of collaborative measurement and calculation of the number, the dam height, the dam spacing and the Z value of the
silt arrester is solved; and different collaborative measurement and
calculation methods are provided for construction projects of different prevention and
treatment targets. According to the method, overall planning is conducted on space and structure parameters of an
elevator dam group by adopting a systematic perspective, and multi-
level design parameters are coordinated in series model expressions of indexes of
energy regulation and control intensity by utilizing a
function model, so that the
planning process can always reflect systematicness of the
elevator dam group and collaborative development of internal units of a dam
group system. The method can also be used for guiding transformation planning of an in-service ladder dam group.
