Description
Technical field
The present invention relates to technical field of tunnel construction, buried groundwater supply in being constructed more particularly, to a kind of tunnel benching tunnelling method
The Blast Vibration Monitoring method of pipeline.
Background technology
In recent years, the Tunnel Engineering that underground water supply pipelines are worn under low coverage is more and more.When being excavated using drilling and blasting method, tunnel
Blasting vibration constitutes safely serious threat to underground water supply pipelines closely, and blasting vibration is easy to cause pipeline to damage,
Even ftracture, cause immeasurable economic loss.
(2013) are saved in Li Jun《Underground utilities safeguard measure is worn under Metro gateway and analysis is calculated》In, calculate and divide
Influence of the concussion of blasting to pipeline is not considered in analysis, blast monitoring method is not proposed yet；And in beam forward (2009)《Underground utilities
Blasting vibration safety test with monitoring》With《Middle Line Project For Transferring Water From South To North Beijing-to-Shijiazhuang section blasting vibration Study on Safety Problem》In, it is proposed that
The ground surface monitoring method of shallow embedding (5m) underground utilities：First, by having laid 4 groups of sensors at earth's surface, underground 5,10,19m,
Every group is buried level to (excavating axis perpendicular to pipeline) and vertical to two sensors, as shown in figure 1, test explosion earthquake
Explosive Vibrating Velocity in ripple, research rock mass at different depth, show that earth's surface vibration velocity value is significantly greater tnan the vibration velocity value at the 5m of underground, two
Person differs 2~3 times；Then, by being surveyed to ground vibration velocity, 5 sights are arranged altogether from quick-fried source to natural gas line direction
Measuring point, minimum distance 36.1m, maximum distance 226.2m (pipeline location), measuring point spacing about presses logarithm equidistantly distributed, draws
Propagation attenuation rule of the attenuation of seismic waves along ground, Charge control is released with this, blast working is instructed.As shown in figure 1, being existing
Have in technology along depth direction sensor arrangement figure, its subject matter and weak point that exist：First, pipeline 5m located underground
Left and right, belongs to the pipeline for comparing shallow embedding, and the Blast Vibration Monitoring problem of deep-buried pipeline is not related to；Secondly, on the other hand pass through
The vibration velocity at different depth in rock mass is tested, show that earth's surface vibration velocity value is significantly greater tnan the vibration velocity value at the 5m of underground, the conclusion is simultaneously
Without generality；Again, by carrying out the attenuation law that actual measurement draws attenuation of seismic waves to ground vibration velocity, do not have to obtain outlet pipe
Explosive Vibrating Velocity at line, the blasting vibration safety of pipeline is controlled with this, and this control is very inaccurate, also relatively dangerous.
For buried (buried depth >=20m) underground water supply pipelines apart from the relatively near (distance≤2D in tunnel it can be seen from more than
(D is tunnel span)) in the case of, there is presently no corresponding Blast Vibration Monitoring method.Existing Blast Vibration Monitoring side
Method is mainly for Shallow-Embedded Under-Ground pipeline, by testing ground blasting vibration velocity, carrys out the blasting vibration safety of indirect control shallow embedding pipeline.
For deep-buried pipeline monitoring problem, due to deep-buried pipeline apart from ground farther out, it is and nearer apart from tunnel, ground vibration velocity with pipeline
Vibration velocity is differed greatly, and in the method for ground vibration velocity control pipeline vibration velocity, for buried underground utilities, then significant discomfort is used.It is another
Existing method, by setting the blasting vibration at deep hole direct measurement pipeline bottom position, party's hair implements very difficult, performance
：One is not allow to set deep hole in many cases；Two be to enable punching, and the installation of sensor is also very difficult, it is difficult to
Ensure the precision installed, implement very difficult.
Therefore, the present invention is directed to the Blast Vibration Monitoring method of buried underground water supply pipelines, because buried depth is big, if still adopted
It is monitored, then will be differed greatly with the actual blasting vibration of pipeline, it is impossible to ensure Tunnel Blasting on ground with above method
Vibrate the safety of underground pipelines, it would be highly desirable to propose a kind of new monitoring method.
