In the present embodiment, dimensionless factor C=2.12, point of a knife pressure coefficient distribution ψ meets：-0.2<ψ<0.2, point width S
Meet：10mm≤S≤92mm, the rolling COEFFICIENT K of rockd=0.55.
In the present embodiment, when shield machine is in horizontal alignment driving, the tunneling direction of shield machine and the angle of horizontal plane
For α, and 5 °≤α≤15 °.
In the present embodiment, the shield cutter rotation band inswept excavation face of cutter, hobboing cutter is tight under the thrust of shield machine
Scar is pressed, as cutterhead rotates, hobboing cutter revolves round the sun around cutter head center axis, and around own axes rotation.Make in the powerful thrust of cutterhead
Under, hobboing cutter is pressed into rock；Under torque effect, hobboing cutter rolls on the joint-cutting of face center.When thrust is more than rock strength
When, the direct attrition crushing of rock under hobboing cutter, hobboing cutter injection rock, face squeezes fragmentation by hobboing cutter and forms tunnel concentric circles
Groove.With the increase of gash depth, rock surface crackle is deepened to expand, adjacent when more than rock shearing and tensile strength
Rock flaking between concentric grooves forms rock ballast, realizes the successful fracture of rock stratum.
Before tunneling construction, first according to the geological condition of compound stratum, point width S is calculated, knife interval S is to determine that hobboing cutter is arranged
The important process parameter of quantity, knife interval S is too big, and the rock between adjacent hobboing cutter can not be abolished, the face in tunneling process
Easily " phacolith " is formed so that tool wear degree is accelerated, and is also easy to so that the shearing force that hobboing cutter is subject to increases suddenly, cause knife
Circle fracture falls off so that tool failure is scrapped.Therefore according to width T, the hobboing cutter between two neighboring hobboing cutter point of a knife
The crushing angle of pile penetration H and compound stratum rockCalculate knife spacingSo that point width S meets rolling
Knife is broken to be needed, and then arranges hobboing cutter installation site according to point width S on cutterhead.Prevent shield cutter eccentric wear, cutterhead from bursting apart
Equal heel and toe wears have the function that protect cutter, extend the service life of cutterhead, saved engineering cost.
Further according to the geological condition of compound stratum, the broken pressure of the hobboing cutter needed during compound stratum tunneling construction is determined
Power, i.e. the actual thrust value F of shield machinet', in calculating process, first calculate single hobboing cutter fracture area pressure P, according to cutterhead
The number of upper hobboing cutter calculates the actual thrust value F of shield machinet'。
During shield-tunneling construction, due to the difference of construction environment, need to use different boring modes.Boring mode point
For under-voltage formula, earth pressure balance pattern.Earth pressure balance pattern is used in upper-soft lower-hard ground, and under-voltage mould is used in ground consisting of hard rock
Formula and earth pressure balance pattern.In the present embodiment, tunnel from the weak weathering of tunneling boring, middle weathering, migmatitic gneiss country rock and completely decomposed,
It is passed through in silty clay, underground water is mainly pore water and Bedrock Crevice Water, and buried depth is split in 2.0~5.0m, part location basement rock
Gap water comparative development.Therefore, under-voltage pattern and earth pressure balance pattern are mainly used in tunneling process.
Tunneling boring hard rock has complete self-stable ability.When being tunneled in hard rock, the vault of shield machine, both sides, suffered by bottom
The equal very little of pressure, the propulsion of shield machine is influenced little, the thrust of shield machine mainly consumes required for hobboing cutter injection rock
Thrust on, it is possible to approximately the power of hobboing cutter injection rock is regarded as the thrust of shield machine, therefore in the present embodiment, passes through
Calculate the effective push mF of the injection rock of multiple hobboing cutters2', obtain the effective push F of shield machine2, i.e. F2=mF2'。
It, need to be according to different geological conditions, different tool wear situations and tunneling process during shield-tunneling construction
In present situation, select corresponding boring parameter.In the present embodiment, boring parameter includes the theoretical thrust value F and shield of shield machine
The torque M of machine knife disk, due to being frequently necessary to correction in shield-tunneling construction, turning to, thrust is bigger, and pile penetration is bigger, under equal conditions
The dregs cut is also more.If the actual thrust value F of shield machinet' excessive, the abrasion of cutter can be aggravated, cause cutter
Disintegrate, cutter ring fracture, fall off, baffle ring fracture, fall off even tool apron deformation, cutterhead deformation.Therefore the actual thrust value of shield machine
Ft', empirically data bigger than the theoretical thrust value F of shield machine, Ft'=1.5F.It is made suitably according to the variation of compound stratum
Adjustment, Rational choice shield machine, it is ensured that shield machine is to the adaptability of compound stratum, carry out shield that can be fast, efficient, safe
Structure tunneling construction.
In Shield Construction Method Used, shield manipulator needs continuously to obtain shield axial location relative to Tunnel Design
The position of axis and the relationship in direction, to make molding tunnel keep correct position.During shield driving, with one
Fixed driving speed excavates forward, needs the run trace of shield consistent with Tunnel Design axis, must obtain data letter at this time
Breath feedback.The tunneling direction of shield machine and being aligned for the theoretical centerline direction in tunnel are realized using laser guide in construction,
To ensure the accuracy of tunneling direction and the control of shield attitude.The adjusting of shield machine tunneling direction is by adjusting every group oil cylinder
Propelling pressure, make shield machine tunneling direction tend to tunnel theoretical centerline direction.When shield Oil cylinder left pressure is big
When right side, attitude of shield machine is put from left to right；When upper lateral pressure is more than lower lateral pressure, attitude of shield machine is put from up to down；
And so on can be adjusted the posture of shield machine.Hinged sealing, tail sealing work in order to ensure shield machine is good, while
In order to ensure that tunnel duct piece is not damaged, shield machine cannot have the tendency that too big during tuning.When shield machine is in water
When horizontal line road is tunneled, the tunneling direction of shield machine and the angle of horizontal plane are α, and 5 °≤α≤15 °, to correct shield machine because of oneself
Heavy and generation bowing phenomena.
The above is only the embodiment of the present invention, is not imposed any restrictions to the present invention, every according to the technology of the present invention
Essence changes any simple modification, change and equivalent structure made by above example, still falls within the technology of the present invention side
In the protection domain of case.
