This paper presents the experiment of new technology of side slope protection by 3-dimensional cover plant combined with jet seeding and discusses the construction technology, its erosion resistance function and the cost-benefit analysis. The experiment shows that the technology is effective for areas with fine sandy soil, high liquid limit side slope and sandy rock soil slope, with soil erosion 20% less than that in areas with simple turf protection and that there is no conspicuous surface layer sliding even under the condition of thunderstorm. In comparison with other side slope protection measures, the cost of the reinforced turf side slope is reduced by 50%-70%, which is new alternative method for side slope protection.
