The device comprises a test stand, a light source system, a sample clamping system, a camera device, a lens shade and after-treatment software. The device is characterized in that a sample held by the sample clamping system is exposed under the light source and is taken photos by a high-speed camera on the other side of the sample to obtain photos showing that the sample interspace is penetrated by optical lines, then percentage of white light spots accounting for total pixel points in the photos is calculated by the after-treatment software to obtain the porosity of the porous media material. Based on optics and statistics principles, the device has simple structure and is easy to achieve; and the test method is simple and convenient and can be widely promoted.
Description
Technical field
The invention belongs to the Geotechnical Engineering field, particularly a kind of laboratory instrumentation of porosity measurement for porous media material.
Technical background
Porous medium is meant the porosu solid that is comprising gas phase and liquid phase, and the porosu solid that wherein contains hole has constituted the deformable skeleton of material, and gas phase and liquid phase are then moved in the hole that is interconnected.Because the effect of pore water pressure, the performance index of porous media material have directly been influenced with the closely-related factor of porosity of material drainage performance.Therefore, the factor of porosity that accurately determines porous media material in theory still all has important practical significance in the engineering practice.
Laboratory determination method at present commonly used seal with wax heavy method in method, the water, drainage, gas expansion method etc., but also not have generally acknowledged best approach.The present invention will utilize optics and statistical principle to measure the factor of porosity of porous medium, for the experimental determination factor of porosity provides a kind of new method and experimental facilities.
Summary of the invention
The object of the present invention is to provide a kind of testing apparatus of porous medium soil body material factor of porosity, solve the test equipment that carries out shop experiment necessity.
To achieve the object of the present invention, the technical scheme of employing is as follows:
A kind of laboratory instrumentation of porosity measurement for porous media material is made up of testing table, light-source system, sample clamping system and picture pick-up device, light shield and the poster processing soft.The steel guide rail is installed on the testing table, and light-source system, sample clamping system and picture pick-up device all are placed on the guide rail by base, and can move on guide rail to adjust spacing.Light shield separates the whole optical path and the external world, is not subjected to the influence of extraneous light with the warranty test result.
Wherein testing table is by platform, and sole-plate, guide rail are formed, and the guide rail cross section is I shape.
Light-source system is by based on halogen bulb, and lampshade, bearing are formed, and based on halogen bulb is positioned in the middle of the lampshade, can regulate light intensity magnitude by rotary switch, and the lampshade inboard scribbles reflecting coating, and bearing is positioned on the guide rail, slidably.
Sample clamping system is made up of clamping plate, sheet glass, bearing.One of sheet glass is the optical glass of high transmission rate, is positioned at the first side of shooting, and one is frosted glass, is positioned at light source one side, and two blocks of glass add jointly holds sample, then is installed on the clamping plate; Adjustable diaphragm is housed on the clamping plate, is used to block the sample marginal ray, geometrical clamp also is housed on the clamping plate, be used for fixing sheet glass; Clamping plate are fixed on the bearing, and bearing is positioned on the guide rail, slidably.
Picture pick-up device is by high-speed camera, bearing and be configured to, and high-speed camera must possess the high zoom function, and it lays about support, front and back are adjustable, and support is installed on the bearing.
Light shield is scalable, is used to provide camera bellows, guarantees to take pictures effect.
The poster processing soft is set up the mapping of pixel and space geometry point, and then obtains the voidage of how empty dielectric material by adding up number percent that white luminous point number accounts for total pixel number.
Advantage of the present invention is:
1. the present invention is based on optics and Principle of Statistics, simple in structure, be easy to realize.
2. test method is easy, and is easy to utilize.
