Consolidation Test China Geotechnical Equipment Supplier

Consolidation Test Definition:

A test method for determining the properties of drainage, venting and bubble compression of soil under external forces. In general, the soil body is subjected to three main stress, and three corresponding changes occur.

Experimental purpose

This test is used to measure the compressibility index of soil, including the compressibility factor AV, the compression index cc and the consolidation coefficient CV, so as to provide the necessary calculation parameters for estimating the settlement of buildings and the degree of consolidation through different time. The greater the consolidation coefficient CV of soil, the faster the consolidation speed of soil is.

Influencing factors

1. The inner wall of the ring knife should maintain a high finish;
2, permeable plate permeability coefficient should be greater than the sample permeability coefficient;
3, the pressure equipment should be able to apply vertical pressure at all levels in an instant, and no impact;
4, displacement sensor precision;
5. The time of measuring meter must not be error.
Operation Steps
(1) Cutting sample: Using ring knife to cut the undisturbed soil samples or to prepare the required state of disturbed soil samples.
(2) Determination of the sample density: the extraction of residual soil to determine the moisture content, when required to saturate the sample.
(3) The specimen is placed: The specimen with a ring knife is placed in the sheath of the compressed container, and in the container the bottom plate, the moist filter paper and the permeable stone are each A, then placed in the pressurized guide ring and the pressure plate.
(4) Check the equipment: Check the pressure equipment is sensitive, adjust the lever level.
(5) Installation scale: The compressed container of the specimen is placed in the center of the pressure table, and the pressure-transmitting steel ball is connected with the concave point of the pressurized beam. Then load the scale, adjust the gauge rod head so that the length of the extension is not less than 8mm, and check the scale is flexible and vertical (in the teaching experiment, students should practice the scale reading).
(6) Apply preload: To ensure that all parts of the compressor contact good, exert 1kPa preload load, and then adjust the scale
Readings to 0.
(7) Pressure observation:
1 load grade is generally 50, 100, 200, 400kPa.
2 in the case of saturated specimens, the first stage of the load should be applied immediately after filling the compressed container with water. If the unsaturated test
, the need for wet cotton yarn around the pressure cover plate for four weeks to avoid evaporation of water.
3 compression stability standards for each level of load under the compression of 24 hours, or the meter reading per hour change is not less than 0.005
MM considers stability (teaching experiments can be assumed to be a stable time). The second stage load is applied after the measured compression stabilized readings are recorded.
Successive loading to the end of the test.
4 after the test, remove the parts of the instrument, take out the specimen, and determine the water content after the test if necessary.
