Bamboo Clump Intercept Study Of Rockfall Mechanism And Scheme

In this paper, through model test and numerical simulation methods to analyze the single Neosinocalamus hit fold the influence factors of the energy required, according to the analysis of the factors, and on the basis of single Neosinocalamus energy dissipation capacity, determined and launch a clump of bamboo hit fold the consumed energy of ability, and discusses the use bamboo grove intercept rockslides. Concrete results are as follows:(1) According to the results of model test analysis, through to new and old Neosinocalamus maximum, minimum and average of comparative analysis, the bamboo sinocalamus affinis age, diameter, thickness, ratio of length to diameter, the energy you need to gain weight than to hit fold Neosinocalamus had obvious effect; Thick sinocalamus affinis collision of height and diameter ratio on the influence of the energy needed to hit fold sinocalamus affinis had no obvious regularity.(2) Analysis, according to the results of the model test sinocalamus affinis age effect on the energy needed to hit fold Neosinocalamus is apparent, the overall trend is larger with age, it is to reduce the energy needed to power a folding Neosinocalamus. 1~3 years, 1 year and 2~3 years of Neosinocalamus hit fold of the energy needed to standard values were 246.79 J, 251.73 J and 235.77 J.(3) Analysis, according to the results of the model test of new and old Neosinocalamus maximum, minimum and average of comparative analysis, the diameter of Neosinocalamus effect on the energy needed to hit fold Neosinocalamus is apparent, the overall trend is as Neosinocalamus diameter bigger, the greater the energy needed to hit fold Neosinocalamus. Newborn bamboo diameter within the range of 35~55mm, 35~40mm, 41~45mm interval, 46~50 mm, 51 and 55 mm interval of the energy needed to hit fold Neosinocalamus standard values were 251.73 J, 201.61 J, 242.15 J, 245.60 J and 254.13 J. Old bamboo in 39~55 mm in diameter, 39 and 40 mm interval, 41~45 mm range, 46~51 mm range to hit fold Neosinocalamus the energy needed to standard values were 235.87 J, 197.84 J, 232.42 J, 236.78 J.(4) According to the results of model test analysis, through to new and old Neosinocalamus maximum, minimum and average of comparative analysis, the thickness of Neosinocalamus effect on the energy needed to hit fold Neosinocalamus, the overall trend is with the thickness of Neosinocalamus thickening, the greater the energy needed to hit fold Neosinocalamus. Newborn bamboo hit fold Neosinocalamus within the range of 4~9 mm thickness of the energy needed to standard value of 251.73 J, the thickness of the new bamboo is 4 mm, 5 mm, 6 mm to hit the energy needed to power a folding Neosinocalamus standard values were 232.89 J, 236.94 J, 253.99 J, the thickness of the newborn bamboo in 7~9 mm range to hit fold Neosinocalamus the energy needed to standard value is 259.44 J. Old bamboo thickness in 4~7 mm of the energy needed to power a range to hit fold Neosinocalamus standard is 235.87 J, the old bamboo thickness is 4 mm, 5 mm of the energy needed to hit fold Neosinocalamus standard values were 218.29 J, 231.94 J, the thickness of the old bamboo in 6~7 mm of the energy needed to power a range to hit fold Neosinocalamus standard is 233.73 J.(5) Analysis, according to the results of the model test of new and old Neosinocalamus maximum, minimum and average of comparative analysis, Neosinocalamus length to diameter ratio of the energy needed to hit fold Neosinocalamus influence is apparent, as the length to diameter ratio increases gradually, the smaller the energy needed to hit fold Neosinocalamus. Newborn bamboo length to diameter ratio, within the range of 65~103, 65~70, 71-76 interval, 77~85, 86~103 interval of the energy needed to hit fold Neosinocalamus standard 251.73 J, respectively, 249.02 J, 259.17 J, 244.25 J, 234.77 J. Old bamboo length to diameter ratio in 65~97, 65~70 interval, 71~79, 81~97 interval to hit fold Neosinocalamus the energy needed to standard values were 235.87 J, 239.17 J, 230.34 J, 225.93 J.(6) According to the results of model test analysis, through to the new and old Neosinocalamus comparative analysis of maximum, minimum and average, long heavy than Neosinocalamus evidently affects the energy needed to hit fold Neosinocalamus, with long heavy than the energy needed to power a bigger hit fold Neosinocalamus is falling. Newborn bamboo grow heavier than within the range of 0.9~2.7 m/kg and 0.9~1.3 m/kg interval, 1.4~1.8 m/kg interval, 1.9~2.7 m/kg of the energy needed to power a range to hit fold Neosinocalamus standard value of 251.73 J, 256.40 J, 245.63 J, 240.07 J. Old bamboo grow heavier than within the range of 1.2~2.2 m/kg and 1.2~1.3 m/kg interval, 1.5~1.6 m/kg interval, 1.7~2.2 m/kg of the energy needed to power a range to hit fold Neosinocalamus standard values were 235.87 J, 231.43 J, 233.07 J, 228.71 J.(7) Neosinocalamus various parameters on the energy needed to hit fold Neosinocalamus, under the influence of Neosinocalamus root number distribution in different energy range statistics, found mostly in the maximum number of root within the range of 232.32~258.13 J.(8) Combined with model test and numerical simulation to estimate a clump of Neosinocalamus minimum consumption of 3975.55 J, the most consumed 10890.88 J.
