| With the rapid development of society and the enhancement of ecological awareness,the stability protection of river slope has developed from internal structural reinforcement to comprehensive management combining inside and outside.The main research contents of this paper are as follows:For the anti-slip piles arranged with different pile positions,pile diameters,anchorage depths and pile diameters on the study slope,the stability of the slope was simulated and analyzed by the calculated safety factor,the internal force of the anti-slip pile,the position of the sliding surface,etc.,and the research results showed that:(1)when the anti-slip pile was set in the middle and lower part of the slope(No.2 pile position),the safety factor was relatively the largest and the supporting effect was the best;(2)Considering the influence of the change of anchorage depth,the simulation calculation results show that when the anchorage depth is 5.5m,it is most conducive to the stability of the slope;(3)The change of the pile diameter of the anti-slip pile has a greater impact on the safety factor,with the increase of the pile diameter,it increases rapidly at first,and when the pile diameter increases to 1.1m,the safety factor value is the largest,and then gradually tends to a stable state.(4)With the increase of pile spacing,the stability of the slope decreases,the safety factor begins to decrease,when the pile spacing is 2.4m,the safety factor is the largest,and the shear force and bending moment of the same section of the anti-slip pile body are the smallest.The ecological protection and treatment of slope slope is analyzed,the functions of ecology,slope protection and landscape of vegetation in ecological protection are introduced,and two types of ecological protection and treatment technologies are summarized,mainly divided into vegetation-type protection and vegetation-engineering material composite protection,in addition,according to the natural climatic conditions such as precipitation terrain,the drainage engineering of the slope is designed and calculated,and finally combined with the types,growth habits and self-generating characteristics of slope protective vegetation,the principle of vegetation selection and planting scheme are proposed.In this paper,a river channel slope of the Jiangjiang-Jinhuai Project is taken as the research object,and the three-dimensional slope model is established by finite element software,and the stability of the slope is analyzed by determining the pile position,pile length,anchorage depth and pile spacing.Calculate the internal force of the anti-slip pile body,draw the pile shear force and bending moment curve at the same time,and reinforce the anti-slip pile.Carry out ecological treatment and protection of slopes,and design slope drainage facilities combining longitudinal and horizontal ditches according to the annual average precipitation in Hefei;According to the collection of climate information,hydrological conditions,vegetation characteristics and surrounding environment,combined with the ecological role of grass and shrub plants and the conclusion that aquatic plants have purified water bodies,the combination of vegetation suitable for growing in the study area was selected to carry out a comprehensive slope ecological protection design combining anti-slip pile and vegetation.Figure [71] Table [14] Reference [95]... |
