Second step, by rock core lobe align, make rock core lobe fastening with clip, then rock core lobe put into the base holes of base;
The material mixture ratio that 3rd step, basis set carries out material weighing, and stirs;
Take the material of single test specimen weight in 4th step, the material that obtains from step 3, the material of single test specimen weight is inserted in the cylindrical cavity of hollow, and constantly carry out compacting with compacting instrument inserting in process;
5th step, when the material of single test specimen weight put into completely hollow cylindrical cavity and after carrying out compacting, the rock core lobe that material is housed is taken out from base and is placed on the platen that adds and present a theatrical performance as the last item on a programme, pressue device is provided with above platen, test specimen pressure head is put into the rock core lobe that material is housed, on the material that test specimen pressure head is pressed in cylindrical cavity;
6th step, unlatching add the pressue device on presenting a theatrical performance as the last item on a programme and act on test specimen pressure head, carry out abundant compacting, and observe the scale on test specimen pressure head surface to the material in rock core lobe;
7th step, when the scale mark on test specimen pressure head surface reaches design load, stop pressurization, material is pressed into test specimen;
8th step, test specimen pressure head to be taken off, after test specimen consolidation certain hour, carry out the test specimen demoulding;
After 9th step, the demoulding, test specimen is put and naturally dries in the shade in the cool.
Beneficial effect:
Synthetic core standard specimen of the present invention makes mould several functions, can making artificial rock core cylindrical standard test specimen, carry out uniaxial compressive, uniaxial tension and single shaft shearing resistance experiment, the synthetic core cylindrical standard test specimen making (not penetrating) with holes can be used for again, carry out the uniaxial compressive experiment of fracture seepage;
According to test specimen prepared by the inventive method, owing to having carried out second weighing and being prepared in strict accordance with scale, the deficiency in the past making mould and method can be overcome, ensure the Sample density that makes and measure-alike, this method for making is easy, be easy to operation, has practicality and generalization widely.
