Flow referring to Fig. 2-4 pairs of hidden quality determining method of shield tunnel structure is described in detail.
The hidden quality determining method of shield tunnel structure includes 5 links：Prepare link, scanning link, identification link,
Calculate link and judge link.Preparing link needs the environment required for preparing scanning for scanning link and sets detection parameter,
Setting suitable detection platform upper strata should be with tunnel vault spacing, center of antenna frequency fcAccording to detection depth selection, when window t roots
Calculated according to equation below：
Wherein h is maximum detection depth, and v is electromagnetic wave spread speed in media as well.
According to Nyquist Sampling Theorems, using frequency fsShould be greater than signal frequency twice i.e.：
fs≥2fc
In scanning link, should be remained a constant speed along tunnel direction and steadily advance, note doing a mark every 5m, and ensure day
Line is close to tunnel surface.
In identification link, treatment forms vertical two-dimensional cross section to the reflection electromagnetic wave that scanning link is received in a program
Picture, two dimensional image forms the section of jurisdiction mud jacking distributed model of three-dimensional through the treatment of three dimensional stress program, and simulation grouting be- hind segment is in sky
Between in distribution.Take as a example by the section of jurisdiction mud jacking distributed model of an endless tube piece, the endless tube piece mud jacking distributed model is open circles
Cylinder shape, a diameter of section of jurisdiction ring internal diameter of hollow area, the radius scan depths of hollow cylinder.It is excessively empty as shown in Fig. 2-(2)
Model is divided into 360 sector regions by the axial pencil of heart its center axis, and sector region angle is 1 °；Such as Fig. 2-(3)
It is shown, then with hollow cylinder central axis as axle, semidiameter is that 1cm coaxial circles cylinder continues segmentation model；Such as Fig. 2-(4) institute
Show, finally on hollow cylinder central axis with 1cm be interval, make perpendicular to hollow cylinder central axis plane continue
Cutting sector region.Section of jurisdiction mud jacking distributed model is divided into some small piecemeals, regards the volume of each small piecemeal as approximate phase
Deng, by defining the characteristics of image in slip casting region and cavity area, identified algorithm is analyzed to each small segmented areas, by
Small segmented areas are defined as ground piecemeal, slip casting piecemeal and cavity piecemeal.
The slip casting piecemeal and cavity piecemeal that calculating link is identified to identification link do further calculating, to slip casting piecemeal,
Analysis judges whether the compactness of grouting of each small piecemeal meets standard, the closely knit angle value for exporting each slip casting region be it is up to standard or
It is not up to standard, when adjacent packing small piecemeal cumulative volume not up to standard is more than given standard, the adjacent area is set to closely knit
Spend low area；It is when adjacent packing region cumulative volume not up to standard is more than given standard, this is adjacent for cavity piecemeal
Region is set to doubtful cavity area, and the adjacent area volume is small piecemeal volume sum.On calculating section of jurisdiction after the wall of certain point
Slip casting thickness, as shown in figure 3, passing through grouting behind shaft or drift lining area perpendicular to center line segment ray by a little sending one on the center line of section of jurisdiction
Domain, two point A, B are met at slip casting region, and coordinate is respectively (Xa, Ya, Za) and (Xb, Yb, Zb), according to the point coordinates of A, B two, with this
Ray is axle, and radius is that δ (appoints and gives ε ∈ R, δ<The computing formula of the slip casting thickness D of cylindrical region ε) is as follows：
Judge that link is judged according to the evaluation criterion of setting to the result of calculation for calculating link, if section of jurisdiction slip casting thickness
D then judges that the endless tube piece mud jacking owes thickness less than setting value, and the too low Domain Volume of packing judges that the region is close more than given threshold
Solidity is unqualified, and doubtful cavity area volume judges to be cavity more than given threshold, is finally completed shield tunnel structure hidden
Cover quality determining method.
