Embodiment
The embodiment of the present invention characterizes the anti-impact of concrete for hydraulic structure to be different from the mass loss amount that previous specification uses
Brush performance, provide a kind of information more comprehensively, it is three-dimensional, more accurately for characterizing different strength concrete scour resistance
Method, this method can probe into suspended load to the ablation destruction on the concrete for hydraulic structure surface during normal service, and wash away to it
Feature is characterized.
Method and step:
According to " concrete for hydraulic structure testing regulations " relevant regulations, what washout test was selected is concrete circular annulated column test specimen, first
First carry out production, demoulding and the maintenance of annulus column concrete sample.
Test specimen pretreatment.It is limited to the related limitation of microscope size and loading weight, is needed before experiment to concrete
Annulus column is pre-processed, and is cut in advance using minitype cutting machine and is taken partial circle inner surface (long generous=50*50*20mm), just
Processing is scanned to it after the completion of period washout test.
Complete concrete washout test.Intend selecting 40min as a test period in scour process.Examination is washed away when one
It tests after the completion of the period, weighs to concrete circular annulated column test specimen, obtain its mass loss amount, while table is washed away to concrete
Face is taken pictures, and determines the exposed area ratio of aggregate, to characterize the extent of the destruction that concrete is washed away indirectly.
Obtain the three dimensional topography in concrete surface each erosion damage stage.It is completed in concrete circular annulated column test specimen different
After the washout test in period, the measurement of mass loss amount, the aggregate bare area ratio of concrete surface are on the one hand carried out to it
Statistics；On the other hand, using the DSX510 type optics digit microscope of Olympus production to wash away the destruction surface of test specimen into
3 D stereo scanning is gone, which is equipped with 3D scanning function, and the three-dimensional stereo topography that can treat test block carries out
Measurement and calculating, and provide the rectangular scan of erosion damage surface of test piece original image under each flush cycle, 18mm*18mm
Region surface three-dimensional appearance figure and surface relative altitude figure, are illustrated in fig. 1 shown below.When computer is completed to concrete destruction surface
After scanning, can shape characteristic parameter to surface, such as area, surface area, mean height of surface parameter calculated and counted.
Parameters revision.Concrete sample used by washout test is loop column type structure, is carried out to circle ring inner surface
When 3-D scanning, internal circular surfaces curvature influences whether surface smoothness.Therefore, when later data is handled, curvature need to be considered to table
Area, the influence for washing away the parameters such as volume are simultaneously accordingly reduced it.
Concrete component is washed away using three-dimensional parameter characterization.Define concrete surface product obtained by the above method and highest point
The volume surrounded between place's plane is characterized volume, for characterizing by the Scouring Characteristic for washing away concrete.By means of filling micromicrofarad
Thought, the mean height of surface value after available concrete erosion damage, to characterize the irregularities of concrete surface and broken
Bad degree with active time development law.
Compared to traditional analysis, there is more obvious technological merit repeatedly herein:
1, more comprehensively to the description of concrete surface characteristic.Traditional characterizing method be bare area after being washed away to water sand,
These two-dimensional signal contents such as changing rule of quantity and size are analyzed and are unfolded.And characterizing method of the invention is then right
