SILT ARRESTER ECOLOGICAL COMBINATION IN MOUNTAIN TORRENTS AND DEBRIS FLOW CHANNEL FORMATION REGION

摘要

Disclosed in the present invention is a silt arrester ecological combination in a mountain torrents and debris flow channel formation region, aiming at solving the defects in the prior art that the comprehensive control measures of ecological engineering and geotechnical engineering lack quantitative design guidance and the initial design conditions are unreasonable. In the silt arrester ecological combination, silt arresters the number of which N ≥ 2 are constructed in a mountain torrents and debris flow channel formation region, and the spacing between adjacent silt arresters is determined by introducing the calculation of aback silting length in front of the silt arrester. The optimized solution also comprises ecological engineering measures, and the ecological combination effect is enhanced by planning different vegetation types on both sides of the channel and in the channel in front of and behind the silt arrester. Specifically provided in the present invention is a method for calculating important design parameters in ecological engineering measures. In the present invention, by designing spacing parameters of adjacent silt arresters, environmental factors of a small space between the silt arresters are adjusted to create a silt arrester ecological combination of a special ecological space, providing a new formation region treatment solution without increasing costs, and providing guidance for the transition of ecological control measures from an empirical qualitative type to an index quantitative type.
