Abstract

The invention discloses a method for determining the optimal plant density of a three-dimensional geonet pad ecological slope protection slope surface, and relates to stability of the side slope or the slope. The method comprises: calculating the runoff depth, the minimum slope soil particle starting speed and the slope average runoff speed according to the runoff coefficient, the slope typical soil particle diameter, the slope roughness, the slope angle, the plant tillering coefficient, the leaf shape, the actual dry volume weight of soil, the stable dry volume weight after compaction, the film water parameter and the comprehensive binding power parameter; obtaining the total transverse row number of plants on the ecological grass planting slope surface according to the relationship between the average runoff speed of the slope surface and the minimum starting speed of slope soil particles; finally, determining the optimal plant density of the slope surface of the three-dimensional geonet pad ecological slope protection according to the total transverse row number of the plants. The defect that in the prior art, the optimal plant density of the slope surface cannot be accurately calculated in the construction process of the three-dimensional geonet pad ecological slope protection is overcome, a large number of surplus purchased grass seeds are prevented, and the engineering cost is greatly reduced.

Description

technical field

[0001] The technical solution of the present invention relates to the stability of side slopes or slopes, specifically, a method for determining the optimal plant density on the ecological slope protection slope of a three-dimensional geotechnical net cushion. Background technique

[0002] As people pay more and more attention to the ecological environment, the "green" method of ecological slope protection has been derived, among which the three-dimensional geotechnical mat ecological slope protection has developed rapidly as a new form of slope protection. This slope protection technology uses the characteristics of plant root reinforcement, transpiration drainage, and stems and leaves to reduce rainwater splash erosion to improve the slope surface cracking, displacement, and runoff infiltration caused by local rainwater erosion, thereby improving the quality of slope engineering. It is conducive to improving the ecological environment of the original slope ...
