Description
Technical field
The present invention relates to a kind of Tunnel prediction technology, specifically a kind of vertical type total space transient electromagnetic tunnel model experimental provision.
Background technology
There are a large amount of Tunnel Engineering in China's water conservancy and hydropower, the field of traffic, in the tunnel excavation work progress, if can not verify in advance the geological condition in tunnel excavation the place ahead, tend to occur unforeseen Geological Hazard, such as gushing water, prominent mud, cave in etc.The consequence that the causes facility that gently then destroy by rush of water flood the tunnel, and normal construction is forced to interrupt; Heavy then cause great casualties and huge economic loss, even construction project is forced to suspend or relocate.So, carry out corresponding advanced prediction work in the tunnel excavation process and just seem and be necessary very much.
Total space transient electromagnetic method is a kind of important Tunnel prediction method.It is quick on the draw to post non of low resistance body, and what receive is by the secondary field that excites vortex induction to go out, no matter the objective body occurrence how, all can be received useful signal, and objective body is carried out imaging.Total space transient electromagnetic method also have efficient height, detection range far away, can carry out simultaneously the advantages such as depth measurement and profile survey, this is so that the method becomes the most promising a kind of method for forecasting advanced geology.
The type of tunnel front geological disaster body and space distribution thereof are comparatively complicated, the total space Transient electromagnetic response feature situation of the disaster body of, different spaces distribution dissimilar in order to understand better, just need to carry out a series of physical simulation experiment, and a good physical model experiment device often can play a multiplier effect.Transient electromagnetic bath scaled model experimental device in the past mainly is the simulated experiment for semispace, but has no report for the bath scaled model experimental device of total space transient electromagnetic method.In addition, the ordinary crossing model is generally horizontal, and inconvenience comes the outside country rock of simulation tunnel with the liquid analog material.
Summary of the invention
The present invention is the total space Transient electromagnetic response the Characteristics of the place ahead, tunnel disaster body, provides a kind of simple in structurely, easy to operate, disturbs few vertical type total space transient electromagnetic tunnel model experimental provision.
The present invention specifically adopts following technical proposals to realize.
Vertical type total space transient electromagnetic tunnel model experimental provision comprises outer barrel, interior bucket and hook; Described outer barrel is upright, its top is provided with bung, and bung is provided with the hole, and interior bucket passes the hole and is fixed on the bung, at least one place in bottom of the barrel outside surface, outer barrel inwall or bung lower surface is provided with hook, fills the liquid analog material of simulation country rock between the described outer barrel and inner barr.
Described inner barrel and outer barrel can be for cylindrical, and the hole on bung and the bung is circle.
Described interior bucket is fixed on the bung by hold-down nut.
The ordinary crossing model equipment is generally horizontal, is difficult to use liquid equivalent material simulating country rock, and this device is vertical type, and is simple in structure, easy to use, allows to use fluent material simulation country rock, has improved applicability of the present invention.
Experimental provision of the present invention all adopts nonmetallic materials in order to reduce the interference to transient electromagnetic field.In addition, in order to guarantee the intensity of material, except hook and hold-down nut, remainder all adopts glass-reinforced plastic material to make.
For the simulation of tunnel cavity, use the interior bucket simulation of inner hollow.And be equipped with hook at the bottom of the barrel outer surface cloth, so that hang anomalous body with fine rule, simulation tunnel face (be equivalent to bucket bottom surface in the present invention, below roughly the same) the place ahead is plastid poorly.
For the outside country rock of simulation tunnel cavity, made an outer barrel, be used for containing the interior bucket of cap analog tunnel cavity, by filling model fluid material between outer barrel and inner barr, reach the outside country rock effect of simulation.In addition, be provided with hook at the outer barrel inwall, can be convenient to fixedly anomalous body.
For the poorly plastid of simulation tunnel side, made bung, its lower surface is provided with hook, in order to hang or with the fixing anomalous body of the hook of outer barrel.Bung and on another outer effect in hole can fix and adjust exactly the degree of depth in the outer barrel goed deep into of interior bucket, thereby can simulate the tunnel of different excavation lengths, also can adjust the space length of front of tunnel heading country rock simultaneously.
Also hang with auxiliary static line on the described hook, in order to fixing anomalous body.
The analog material of described simulation country rock or liquid analog material are known technology, but concrete application reference number is 200810158522.9,201110427064.6,201210189082.X, 201120074257.3,200910061808.X or 200910017549.0 patent document.
Actual application of the present invention is simple to operate: before the use, according to calculating similar situation, choose suitable country rock simulation material and be placed between the inside and outside bucket, set simultaneously the anomalous body that needs experimental study, then according to the interior bucket of tunnel excavation length adjustment simulation tunnel.After finishing, setting just can arrange that wire frame carries out simulation experiment study in bottom of the barrel.
The invention has the beneficial effects as follows, satisfy the use of model fluid material and be designed to vertical type, and simple in structure, easy to operate, disturb and lack, can satisfy well total space transient electromagnetic simulated experiment requirement.When utilizing this experimental provision to carry out simulated experiment, by conversion different anomalous body and suspension or stationary state, can carry out effectively modeling effort to the total space Transient electromagnetic response of some common geologic hazard bodies is special.
