Description of the drawings
Fig. 1 is the flow chart of the present invention.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
The present invention provides a kind of great soil group and names method, for quickly being named to great soil group.
The method of the present invention includes the following steps：
ST1：It is after obtaining part of it sample, soil sample is evenly laid out in surface color and great soil group color tool for soil sample to be measured
Have on the platform of bigger difference；The photo of soil sample on platform is obtained by image acquiring device.
Since the particle of figure class is smaller, different great soil group particle diameter gaps is smaller, and common video camera can not be accurate
The photo of soil sample is obtained, therefore, it is preferable to use the acquisitions that scanning electron microscope carries out soil sample photo in the present invention.
ST2：For the photo that ST1 is obtained, processing analysis is carried out to photo, obtains the hole in photo, and calculate by hole
The diameter of all particles that gap is isolated.
In the step, when handling photo, using image J softwares.The software can carry out at gray scale photo
It manages and identifies the hole of picture, and the diameter of the particle detached by hole can be calculated, therefore, using image J softwares
After the photo gray proces of soil sample, the gap of soil sample and particle diameter in photo are obtained.
ST3：All particles obtained in ST2 are divided according to different diameter ranges, which presets, if
Timing is set according to the requirement of great soil group diameter specification；Due to being directed to same great soil group particle, diameter would generally be
It floats in certain range, therefore, the division of diameter range can be carried out first, then calculate different-diameter to the particle diameter of acquisition
The granule content of range.
ST4：Ask for all particles of each diameter range area and, and calculate all of each diameter threshold range
The area of grain and the area ratio with the soil sample gross area in soil sample photo；
ST5：According to mass ratio of the area than being approximately equal to particle, according to different-grain diameter range and its corresponding granular mass ratio into
Row great soil group is named.Specifically, it can refer to《Exploration of geotechnical engineering specification》Specified in different mass ratio and particle size range
Control carries out great soil group and names.
As a kind of embodiment, the present invention is to mainly including gravelly soil（High power camera）, sand, silt and clay
The great soil group of grain is named.
First, according to《Exploration of geotechnical engineering specification》, granular mass of the grain size more than 2mm is more than the soil of gross mass 50%, fixed
Entitled gravelly soil, and the division can further classify；Granular mass of the grain size more than 2mm is no more than 50% and grain size of gross mass
Granular mass less than 2mm, more than 0.075mm is more than that the soil of gross mass 50% is named as sand, which also can further divide
Class.
It will be laid on platform after name mound sampling, the photo of sample obtained by scanning electron microscope, and use
Image J softwares obtain its internal particle diameter, and count the quantity of the particle of each diameter, then to diameter more than 2mm's
The area ratio of particle is calculated, while the area ratio of particle of the grain size more than 0.075mm is calculated, and the area is than approximate
Equal to mass ratio.If granular mass of the grain size more than 2mm is more than gross mass 50% in the sample, which names as gravelly soil；
If 50% and grain size that granular mass of the grain size more than 2mm is no more than gross mass are less than 2mm, the granular mass more than 0.075mm
More than gross mass 50%, then name as sand.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, several changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
