Description
Technical field
The invention belongs to engineering survey field, the virtual two-conductor line of more particularly to a kind of subterranean tunnel controls measuring method.
Background technology
Underground tunnel project control measurement is divided in hole and two parts outside hole, and control measurement purpose is to ensure subterranean tunnel work
The working face that Cheng Xiangxiang is excavated by the correct insertion of precision of regulation, and can be such that every building repaiies by design attitude and geometry
Build, do not invade track clearance, meet examination required precision, all kinds of engineerings have corresponding specifications of surveys to have strictly piercing error
Regulation, different specification regulation is variant, as a example by requiring higher High Speed Rail Projects to underground tunnel holing through,《High-speed iron
Road Code for engineering surveying (TB10601-2009)》Underground tunnel through error is made and is specified below：
Regulation of the Tunnel control network survey to piercing error
In Practical Project work progress, often have and cause liner sections to invade tunnel because subterranean tunnel piercing error transfinites
Road headroom and causing repair chisel, do over again, line transfer, few up to a million of economic loss, at most up to ten million, control tunnel through error is extremely
It is important.
Present measurement of the level means and high-precision leveling instrument, meet specification over the ground by measuring by specification
The requirement of lower tunnel elevation piercing error；Outside tunnel control survey due to observation condition preferably, the applications of GPS measurement means,
Code requirement also can easily be met by impact part of the outer control measurement in hole to tunnel lateral direction penetrating error；The internal control of subterranean tunnel hole
Net processed is progressively pushed ahead in work progress and built up, and front end is without known point constraint, error or all proportional radiation of mistake
Shape expands, and whether become subterranean tunnel can be by the crucial measurement links of specification specification error insertion.
The current method of subterranean tunnel Horizontal control in tunnel has two kinds：
A kind of method is open traverse：Wire extends out successively from known control point and does not conform to, is not closed to appoint
On what known control point.
Open traverse measurement advantage be：Laying is simple, flexible, measurement workload is little, and it has the disadvantage：Because open traverse lacks
Condition is checked, is made a mistake in observation or calculating process or rough error cannot be found by checking, therefore only in subterranean tunnel
Length is very short, certainty of measurement is adopted when requiring relatively low.
Another kind of method is two-conductor line：Two points are laid in pairs at every place when traverse point is laid, and also can all around be staggered
Arrangement, a polygonal circuit is constituted during observation per 4～6 sides.
Two-conductor line measurement advantage be：The excess observation component that net can be rolled up, the closure for increasing wire check condition, carry
The bulk strength and precision of height net, at present this kind of method is in the subterranean tunnel plane control survey that length is longer, required precision is higher

Process, and to set two-conductor line in narrow subterranean tunnel lining, good sighting condition, avoiding barrier, in pairs should be ensured
Lay traverse point and network forming forms closure ring, reconnaissance pile anchoring is not only extremely difficult, and pile anchoring quantity is more, and control is laid in reconnaissance pile anchoring
Net high cost processed；When field operation is measured, the time of the real measurement per survey station is relatively-stationary after preparation is carried out, for not
Biconditional operation personnel's time of measuring is also no much difference, often the time of a tunnel Traverse Survey, and major part is
Be used in and looked for barrier, connection lighting apparatus in point, cleaning sight line, set up in the preparation such as measuring apparatus, field operation measurement with
The interlaced impact of constructing tunnel, measurement efficiency is extremely low, and measurement is controlled in subterranean tunnel hole to make measurement and construction cost, enter
Degree is all severely impacted；Because industry software part is greatly developed in computer and measurement, make different survey crews process in industry
Performance data efficiency is very nearly the same；Analyze more than comprehensive, want control measurement cost in subterranean tunnel hole and controlled, measurement effect
Rate is improved, and can only find breach on control net is laid in reconnaissance pile anchoring and field operation measurement data is collected.
