Vane shear test field experiment

vane shear test field experiment Since vane shear strength values are most always higher than field strengths for analyses (53) they often are checked or compared with other methods of measuring undrained shear strength cone penetrometer tests (test method d5778) and unconsolidated undrained triaxial compression (d2850) tests are most often performed for direct comparison to the vane shear strength data.

In this video i have talked about the vane shear test which is used to find out the shear strength of the plastic clay in the field or in the laboratory hello everyone, hope you liked the video this is an educational platform set up iit bombay graduates with an aim to prepare you for competitive exams like gate, ese, etc, and to widen your knowledge in civil engineering. Vane shear test is used to measure the shear strength of a soil it also estimated and measured the fully saturated clay’s undrained shear strength without derangement in the specimen this test can be conducted in field and laboratory however, in laboratory can only execute the experiment with. In soil, shear strength is contributed by the two properties cohesion, and angle of internal friction in pure clays the shear resistance due to internal friction is negligible hence, the complete shear strength in clays is due to cohesion (c) apparatus vane shear test apparatus the vane shear test apparatus consists of a torque head mounted on a bracket. The vane shear test is an in-situ geotechnical testing methods used to estimate the undrained shear strength of fully saturated clays without disturbance the test is relatively simple, quick, and provides a cost-effective way of estimating the soil shear strength therefore, it is widely used in geotechnical investigations. From table 10, the values for the undrained shear strength of the soil for the first trial using the medium vane, larger vane, and smaller vane are as follows: 18kn/m3, 17 kn/m3, and 19 kn/m3, respectively.

11 this test method covers the field vane test in saturated clay and silt soils for determination of undrained shear strength knowledge of the nature of the soil in which each vane test is to be made is necessary for assessment of the applicability and interpretation of the test. Immediately repeat the vane test to determine the remolded vane shear strength after the test select a representative portion of the sample for a water content determination data from the vane test are recorded in the term of a spring deflection and a vane deflection on the data and calutation sheet.

This test can be conducted in field and laboratory however, in laboratory can only execute the experiment with low shear strength (03 kg/cm2) for which unconfined test cannot be performed the test apparatus are composed of 3 different diameters of 4-blade stainless vane that is attached in a steel rod that pushed vertically in the soil. Vane shear test – field experiment posted on november 13, 2017 by edusee12aapbn23 analysis the vane shear apparatus makes use of the theory that the summation of the total shear stress is equal to the sum of the shear stress at failure along the cylindrical surface and the total shear stress on the top and the bottom of the surface of the. Comparison of in-situ shear strength measurement techniques of soft clays jeff schaeffers, conetec investigations ltd, richmond, bc, canada the field vane test data is presented from both test methods for peak and remolded strengths 42 electric vane shear test results figure 6 shows the electric vst from 65 m depth the.

Shearing strength of soils and its tests vane shear test the undrained strength of soft clays can be determined in a laboratory by vane shear test the test can also be conducted in the field on the soil at the bottom of bore hole the apparatus consists of a vertical steel rod having four thin stainless steel blades or vanes fixed at its. Vane shear test apparatus the vane shear test apparatus consists of a torque head mounted on a bracket four shear vanes are fixed on a shaft and the shaft is fixed in the lower end of a circular disk graduated in degrees. In this video i have talked about the vane shear test which is used to find out the shear strength of the plastic clay in the field or in the laboratory hello everyone, hope you liked the video.

Vane shear test on soil the vane shear test apparatus consists of four stainless steel blades fixed at right angle to each other and firmly attached to a. The vane was deployed through 425 inch hollow stem augers, with the middle of the vane pushed 06 metres below the bottom of the hollow stem auger bit all vane tests were performed using a rectangular shaped vane, measuring 75mm wide by 150 mm long the field vane testing was carried out in accordance with astm d 2573-01 (2001) figure 2.

The vane shear test apparatus consists of four stainless steel blades fixed at right angle to each other and firmly attached to a high tensile steel rod the length of the vane is usually kept equal to twice its overall width. Vane shear test the undrained strength of soft clays can be determined in a laboratory by vane shear test the test can also be conducted in the field on the soil at the bottom of bore hole.
