Feature in embodiment can be combined with each other.The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment of the method:
Referring to Fig. 1, Fig. 1 is the process that power transmission tower tower leg provided in an embodiment of the present invention auxiliary material support force determines method
Figure.As shown, power transmission tower tower leg auxiliary material support force provided in an embodiment of the present invention determines that method includes the following steps:
Identification step S1 identifies three auxiliary materials support of tower leg from the power transmission tower tower leg spatial model constructed in advance
The face V in face.
Specifically, referring to Fig. 6 to Fig. 8, power transmission tower tower leg spatial model is previously according to relevant design regulation building, originally
Embodiment is to be determined to the tower leg auxiliary material support force in the model having been built up.The tower leg of power transmission tower can be set
Multiple, multiple tower legs are arranged symmetrically, and the structure of each tower leg is identical, and the present embodiment is by taking one of tower leg as an example
It is illustrated.In the specific implementation, tower leg can also be set as different height according to topography situation.In the spatial model
In, according to the coplanar principle of rod piece, identify three auxiliary material supporting surfaces of tower leg, i.e. front 800, side 900 and the face V 700.
Step S2 is calculated, the support force enhancement coefficient in the face V is calculated.
It referring to figs. 7 and 8, is included main material 510 and oblique material 520 by dead-wood 500.The face V 700 be to the oblique material 520 of tower leg into
Row support, since oblique material 520 can use angle steel, then the face V 700 and the place face of oblique material angle steel a line have angle, oblique material
Face where the another a line of angle steel is front 800 or side 900, that is to say, that the face V 700 has with front 800 or side 900
Angle, so then needing to calculate the support force increase system in the face V in order to ensure the requirement that the enabling capabilities in the face V reach design standard
Number.Wherein, since front 800 and side 900 are symmetrical two faces, so angle, the face V between the face V 700 and front 800
Angle between 700 and side 900 is equal.When the angle between the face V 700 and front 800 or side 900 is bigger, the face V
700 supporting roles that rise are better, and support force enhancement coefficient is with regard to smaller.Conversely, when the face V 700 and front 800 or side 900 it
Between angle get over hour, the supporting role that the face V 700 is risen is poorer, and support force enhancement coefficient is bigger.
Selecting step S3 chooses supporting point on the face V, which is the tie point by dead-wood and auxiliary material of tower leg.
Specifically, due to the face V 700 be the oblique material 520 of tower leg is supported, so, have multiple oblique materials on the face V 700
520 with auxiliary material 600 tie point, then these tie points can be used as supporting point, that is to say, that have multiple on the face V 700
Support point.
Determine step S4, according to calculated support force enhancement coefficient, selection the face V on supporting point where by dead-wood
Support force coefficient and the determination of axis pressure should be applied to the support force of the supporting point on the face V.
Specifically, the supporting point chosen on the face V 700 in above-mentioned selecting step S3 has multiple, is applied to each supporting point
Support force calculated, now by taking one of supporting point as an example for be clearly applied to surely the supporting point support force side
Method.The face V 700 choose supporting point corresponding to by dead-wood 500 be oblique material 520, according to " overhead power transmission line pole tower structure is set
Meter technical stipulation " in " and shaft tower auxiliary material support force provided by its supporting point be generally not less than supported main material internal force
2%, 5% " requirement of oblique material internal force, it is determined that the support force coefficient by dead-wood where the supporting point chosen on the face V is
5%.Axis pressure be choose the face V on supporting point where the axis pressure namely axis pressure by dead-wood be oblique material 520 axis pressure
Power.It when power transmission tower tower leg spatial model calculates, should first calculate by dead-wood, then auxiliary material is calculated, so
Axis pressure by dead-wood is precalculated.It will be on the face V that calculated support force enhancement coefficient in step S2, selection be calculated
Supporting point where the product of force coefficient and axis pressure is supported by dead-wood to determine the branch for the supporting point being applied on the face V
Support force.
As can be seen that assisting the face V in material supporting surfaces by identifying three of tower leg, and calculate the face V in the present embodiment
Support force enhancement coefficient, it is common in conjunction with the support force coefficient and axis pressure by dead-wood where the supporting point chosen on the face V
Determine and be applied to the support force of supporting point on the face V, calculate simple, conveniently, improve the accuracy of calculating, additionally it is possible to by the face V with
The influence of the angle in front or side is taken into account, so that the support force in the face V can satisfy the requirement of design standard, it is ensured that tower
The stability of leg solves the support force for the supporting point being applied on the face V in the prior art because being unable to reach wanting for design standard
It asks and there are problems that security risk, also, the support force enhancement coefficient in the face V can effectively guarantee that the enabling capabilities in the face V are full
The requirement of sufficient design standard, it is ensured that the safety of tower leg.
Referring to fig. 2, the identification step S1 in above-described embodiment further comprises:
Step S11 calculates the angle between three auxiliary material supporting surfaces of tower leg in spatial model and ground.
Specifically, referring to Fig. 7, in power transmission tower tower leg spatial model, according to the coplanar principle of rod piece, tower leg is identified
Three auxiliary material supporting surfaces have certain angle between these three auxiliary material supporting surfaces and ground, by each auxiliary material supporting surface
Angle between ground calculates separately out.
Step S12, by the smallest auxiliary material supporting surface of angle determines between ground in three auxiliary material supporting surfaces
For the face V；Remaining two auxiliary material supporting surfaces are identified as a front surface and a side surface.
Specifically, the angle between material supporting surface and ground is assisted to compare by calculate in above-mentioned steps S11 three,
The smallest auxiliary material supporting surface of angle is determined as the face V 700, remaining two auxiliary material supporting surfaces are then identified as just
Face 800 and side 900.Since front 800 and side 900 are symmetric designs, so front 800 and side 900 are not distinguished, it will
One of them in remaining two auxiliary material supporting surface is determined as front 800, then another is determined as side 900.
As can be seen that in the present embodiment, by calculating the angle between three auxiliary material supporting surfaces of tower leg and ground, and
The smallest auxiliary material supporting surface of angle is determined as the face V, can accurately be determined the face V, and then ensure subsequent
Calculate the accurate calculating of the support force enhancement coefficient in step S2 to the face V.
Referring to Fig. 3, the calculating step S2 in above-described embodiment further comprises:
Step S21: tower leg front or the angle β between side and the face V are calculated.
Specifically, since the front 800 of tower leg and side 900 are symmetric designs, so, the front 800 and the face V of tower leg
700 angle, the side 900 of tower leg and the angles of the formation of the face V 700 formed, the two angles are identical, are β.Wherein, the meter of β
Calculation process is known to those skilled in the art, therefore does not repeat.
Step S22: 1/sin β is determined as to the support force enhancement coefficient in the face V.
Specifically, when the angle β between the face V 700 and front 800 or side 900 is bigger, the support that the face V 700 is risen is made
With better, then the support force enhancement coefficient determined according to 1/sin β is smaller, and the active force for being applied to supporting point on the face V 700 is got over
It is small.Conversely, the supporting role that the face V 700 is risen is poorer, then root when the angle β in the face V 700 and front 800 or side 900 is smaller
The support force enhancement coefficient determined according to 1/sin β is bigger, and the active force for being applied to supporting point on the face V is bigger.
Because the supporting role that the face V 700 is risen is poorer when the face V 700 and the angle β in front 800 or side 900 are smaller, this
When in order to enable the supporting role in the face V 700 reach design standard requirement, then need to increase support force enhancement coefficient, to increase
It is applied to the active force of the supporting point on the face V.Again due to the supporting point being applied on the face V active force with front or side phase
Component on vertical direction is the support force for the supporting point being applied on the face V, so being applied to the support of supporting point on the face V
Power is also just corresponding bigger, so that the support force in the face V can satisfy the requirement of design standard.
As can be seen that being determined in the present embodiment according to tower leg front 800 or the angle between side 900 and the face V 700
Support force enhancement coefficient effectively ensures the accuracy of support force enhancement coefficient, and then ensure that the support being applied on the face V
The accurate calculating of the support force of point, reduces error rate.
Referring to fig. 4, above-described embodiment can also calculate tower leg front on supporting point support force, can specifically include as
Lower step:
Step S5 chooses supporting point in front.
Specifically, supporting point is chosen on front 800, which is the company by dead-wood 500 and auxiliary material 600 of tower leg
Contact.Supporting point have it is multiple, now by taking one of supporting point as an example for be clearly applied to surely the supporting point support force side
Method.
Step S6 is supported the product of force coefficient and axis pressure true according to where the supporting point on the front of selection by dead-wood
Surely the support force of the supporting point on front should be applied to.
Specifically, where the supporting point chosen on front 800 can be main material 510 by dead-wood 500, or tiltedly
Material 520.According in " overhead power transmission line pole tower structure-design technique regulation ", " shaft tower auxiliary material props up provided by its supporting point
Support force is generally not less than 5% " requirement of the 2% of supported main material internal force, oblique material internal force, then chooses when on front 800
Where supporting point by dead-wood 500 be main material 510 when, support force coefficient be 2%；When the supporting point institute chosen on front 800
By dead-wood 500 be oblique material 520 when, support force coefficient be 5%.Axis pressure be choose front on supporting point where by
The axis pressure of dead-wood, the axis pressure are precalculated in power transmission tower tower leg spatial model.By axis pressure and corresponding support
The product of force coefficient determines the support force for the supporting point being applied on front.
As can be seen that in the present embodiment, by choosing supporting point in front, and by supporting point place by the support of dead-wood
The product of force coefficient and axis pressure determines the support force of the supporting point, and it is simple, accurate to calculate, also, since front 800 is tower
The main support face of leg, the face where the another a line of oblique material angle steel is front 800, then angle is zero, so without considering
The influence of angle, the support force for the supporting point being applied on front can satisfy wanting for design standard between front and tiltedly material angle steel
It asks, it is ensured that the stabilization of tower leg.
Referring to Fig. 5, above-described embodiment can also calculate the support force of the supporting point on tower leg side, can specifically include as
Lower step:
Step S7 chooses supporting point in side.
Specifically, supporting point is chosen on side 900, which is the company by dead-wood 500 and auxiliary material 600 of tower leg
Contact.Supporting point have it is multiple, now by taking one of supporting point as an example for be clearly applied to surely the supporting point support force side
Method.
Step S8 is supported the product of force coefficient and axis pressure true according to where the supporting point on the side of selection by dead-wood
Surely the support force of the supporting point on side should be applied to.
Specifically, where the supporting point chosen on side 900 can be main material 510 by dead-wood 500, or tiltedly
Material 520.According in " overhead power transmission line pole tower structure-design technique regulation ", " shaft tower auxiliary material props up provided by its supporting point
Support force is generally not less than 5% " requirement of the 2% of supported main material internal force, oblique material internal force, then when choosing on side 900
Where supporting point by dead-wood 500 be main material 510 when, support force coefficient be 2%；When the supporting point institute chosen on side 900
By dead-wood 500 be oblique material 520 when, support force coefficient be 5%.Axis pressure be choose side on supporting point where by
The axis pressure of dead-wood, the axis pressure are precalculated in power transmission tower tower leg spatial model.By axis pressure and corresponding support
