Embodiment two
Referring to Fig. 5, the curved design of curved top plate 8 and curved top beam 7 in embodiment one is described in detail in the present embodiment
Method.
The top surface of curved top beam 7 is identical as the top surface of curved top plate 8, and the top surface of curved top plate 8 is one section of opening upwards
Parabola is that bus translates the curved surface to be formed, by determining that the parabolical shape can determine curved top plate 8 and curved top
The curve form of beam 7.
X-y plane coordinate system as shown in Figure 5 is established, makes vertex of a parabola on reference axis x；Overstriking line is hangar tunnel in figure
The parabolic type of the curved top plate of structure, enabling this section of parabolical lower extreme point abscissa is 0；Given highway 2 is had a lot of social connections W=10m, can
If the curved top plate of hangar tunnel projects long 10m along x-axis, then parabolical upper extreme point abscissa is 10.Setting entire parabolic equation can
For y=a (x+b)2, a in formula, b is undetermined parameter；Calculating the parabolical derivative equation is y '=2ax+2ab.By mathematics knowledge
It is found that the slope that certain is put on parabola is equal to the derivative of the point, can be joined by determining the slope of two o'clock on parabola
The numerical value of number a, b, choose parabolical upper extreme point here and lower extreme point are calculated, and corresponding hangar tunnel top surface enters object mouth and out object
Mouthful.
According to force analysis of the falling rocks on curved top plate 8, it is desirable that top surface any position equal energy of the falling rocks in curved top plate 8
Enough smoothly to slide, need to guarantee: Gsin θ >=μ Gcos θ, i.e. tan θ >=μ, wherein G is falling rocks gravity, and μ appoints for curved 8 top surface of top plate
The coefficient of friction of meaning position, θ are the tangential angle of the parabola any position of curved top plate 8, i.e., arbitrary point is oblique on parabola
Coefficient of friction of the rate not less than corresponding curved 8 top surface of top plate
For Conservative estimation, the coefficient of friction of polytetrafluorethylecoatings coatings takes μ=0.2, therefore need to guarantee θ >=μ=0.2 tan.
Ensure that hangar tunnel top surface lower extreme point slope not less than its coefficient of friction, can enable parabola lower extreme point slope y (0) '=tan
θ1=0.2, that is, it can guarantee that mudstone smoothly slides；If upper extreme point slope y (10) '=tan θ2> 0.2 is being greater than 0.2 friction system
The coefficient of friction that the point is taken in number is 0.7, and parameter a=0.025, b=4 is obtained by calculation.
The then parabolical whole equation are as follows:
Y=0.025x2+ 0.2x+0.4,
7 curved surface of curved surface top plate in the present embodiment takes the parabola to be added at one section of abscissa (0,10) as bus
Work.
Hangar tunnel top surface each point coordinate can be determined by parabolic equation, with this prefabricated model, wherein hangar tunnel lower extreme point
Coordinate is (0,0.4), and hangar tunnel upper extreme point coordinate is (10,4.9), therefore endpoint differs 4.5m to hangar tunnel up and down, and difference in height is reasonable.
The hangar tunnel top surface that above parabolic curve is formed can make to fall within mud-rock flow thereon and Rolling Stone in self gravity and
It still can voluntarily be slid under the action of impact force, realize the guiding function of mud-rock flow and Rolling Stone, efficiently solved siltation and ask
Topic reduces later period operation cost.
