2 Measure the diameter and height of the shear box.

. It is made up of basically the components. Questa Mine Site TEST DATE. November 15 2017 Prepared for.

The objective of direct shear test is to determine the shearing strength of soil using the direct shear apparatus. From the plot of shear stress verses the horizontal displacement the maximum shear stress is obtained for a specific vertical confining stress. INTRODUCTION The test is carried out on either undisturbed samples or remoulded samples.

1 Weigh the initial mass of soil in the pan. Direct shear test is used to predict these parameters quickly. A direct shear machine applies a predetermined vertical load normal stress to the soil specimen in the shear box assembly.

Graph for Normal loading of 50 KNm2 Figure 10. Lecture 1 introduction and properties of soil. Direct shear test is used to predict the internal friction angle and cohesion of soil which are required in many engineering problems such as design of foundation retaining walls slab bridges pipe and.

The direct shear apparatus. IN-SITU DIRECT SHEAR TEST REPORT PROJECT. Insitu and lab test Shah Naseer.

KEY WORDS AND DOCUMENT ANALYSIS a. The shear strength parameters of the soil sample tested through direct Shear Test in laboratory are found to be C -00260 approx φ 3617 Comparison with expected result. WHEN 10 MM DIAMETER PILLARS WERE INTRODUCED.

A shear box or shear ring contains the soil specimen and consists of two halves stacked vertically. In this laboratory a direct shear test device will be used to determine the shear strength of a cohesionless soil ie angle of internal friction ɸ. Direct shear of soil according to astm d 3080.

Shear displacement mm Horizontal Dial Reading x 000254 Shear Stress kNm2 Shear force Area of soil sample Then from the data we. RESULTS OF DIRECT SHEAR TESTS WHEN SAND COLUMNS WERE INTRODUCED IN THE SOIL. Molycorp In-situ Direct Shear Test TEST NO.

Graph for Normal loading of 100 KNm2 Figure 11. The purposes of the testing program were to determine the shear strength parameters at the soil-geomembrane interface and to examine the precision of the direct shear test. Compute 15 of the diameter in millimeters.

The direct shear test is one among the oldest strength tests for soils. Result Obtained from Direct Shear Test. The laboratory report cover the laboratory procedures for determining these values for cohesionless soils.

The aim of this direct shear test is to determine the shearing strength of soil using. Direct shear box apparatus. Graph for Normal loading of 150 KNm2 TABLE 9.

By using the given data of normal stress which are 1389kPa 2948kPa and 4490kPa with horizontal dial reading and shear force we have to calculate the shear displacement mm and shear stress T kNm2 by using the formula. Assemble the shear box as indicated in. 3 Carefully assemble the shear box and place it in the direct shear device.

Aaron Gallardo Christopher Hourigan Riley Haubrich Introduction and Objective. The applied normal stresses depend on the loads anticipated in the design. Loading frame motor attached.

Engineering Properties of Soils Based on Laboratory Testing Prof. Krishna Reddy UIC Test Procedure. Lateral Earth Pressure.

DESCRIPTORS-- water conservation1 geosyntheticsl canal lining b. 1 Theory The strength of a soil depends of its resistance to shearing stresses. To facilitate the remoulding purpose a soil sample may be compacted at optimum moisture content in a compaction mould.

Compact sample in a 60mm x 60mm x 20mm cutting ring. Direct shear test is used to predict these parameters quickly. Up to 24 cash back DIRECT SHEAR TEST OBJEVTIVES To determine the shear strength parameters for a given soil using the direct shear test.

November 8 2017 Date of report. Demetri Dorceus Group Members. Direct Shear Test Date of lab.

The strength of a soil depends of its resistance to shearing stresses. It is made up of basically the components Frictional due to friction between individual particles. Prepare the soil sample by adding small quantities of water and mixing until clay becomes stiff take care not to make sample to wet.

The laboratory report cover the laboratory procedures for determining these values for cohesionless soils. The primary purpose of this. Objective For any soil Cohesion C and Angle of Internal Friction Ø are two important engineering properties which indicate the shear strength of soil.

It is shown from the above value of φ 3617 that the given sand sample is dense sand of uniform grain size. These two parameters are required for design of slopes calculation bearing capacity of any strata calculation of consolidation parameters and in many other analyses. The bottom half of the shear box is held in.
