This report presents the results of the testing program.

. Engineering properties of soils based on laboratory testing. Among which one of the most common and simplest methods is the direct shear test using shear box apparatus which can be used to determine the shear strength parameters cohesion c and internal angle of friction φ under various normal stress and shear strain rate conditions. Direct shear test is used to predict these parameters quickly.

Direct shear test is used to predict these parameters quickly. CIVE1108 GEOTECHNICAL ENGINEERING 2. Prepare the soil sample by adding small quantities of water and mixing until clay becomes stiff take care not to make sample to wet.

For samples taken with thin-walled tube samplers the direct shear sample is typically circular and either has the same diameter as the inside of the sampling tube or preferably is smaller by an amount that allows for trimming away the disturbed outer zone. 10232019 CIVL 2106 Lab Report on Shear Box Test Felix Cheng UID. DESCRIPTORS-- water conservation1 geosyntheticsl canal lining b.

ASTM D 3080 - Standard Test Method for Direct Shear Test of Soils Under Consolidated Drained Conditions Significance. These two parameters are required for design of slopes calculation bearing capacity of any strata calculation of consolidation parameters and in many other analyses. In case of cohesive soil drainage time will be more and there is no control over drainage as in case of triaxial test hence it is suitable for sandy soils.

In this laboratory a direct shear device will be used to determine the shear strength of a cohesionless soil ie. THE DIRECT SHEAR TEST CAN BE PERFORMED TO DETERMINE THE INTERNAL ANGLE OF FRICTION AND THE COHESION OF THE SOIL. A schematic diagram of the direct shear test apparatus is shown in Figure 92.

Direct Shear Test Lab Report. Compact sample in a 60mm x 60mm x 20mm cutting ring. 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.

Equipment Used Figure 1. Direct shear testing and the reader is referred to azam and wilson 2006 for further test results. Direct shear test is used to predict these parameters quickly.

Direct shear test of soil is a relatively simple soil mechanics test run on cohesive or non-cohesive samples of undisturbed or remolded soil materials. It is made up of basically the components. Shear strength is defined as the maximum resistance that a material can withstand when subjected to shearing.

The test equipment consists of a metal shear box in which the soil specimen is placed. DIRECT SHEAR TEST 1. 1 Theory The strength of a soil depends of its resistance to shearing stresses.

Objective For any soil Cohesion C and Angle of Internal Friction Ø are two important engineering properties which indicate the shear strength of soil. The laboratory report cover the laboratory procedures for determining these values for cohesionless soils. AFTER THE CALCULATIONS THE INTERNAL ANGLE OF FRICTION IS 571 O WHILE THE COHESION WAS BETWEEN 684-747 POUNDS DEPENDING ON HOW CALCULATIONS WERE PREFORMED.

Introduction It was of paramount important for an engineer to be able to estimate the strength and strain properties of a soil sample at a glance of its basic properties. The aim of this direct shear test is to determine the shearing strength of soil using. Angle of internal friction f.

Song Due April 17th 2018 Purpose The purpose of this lab is to determine the angle of friction for the soil sample in this case sand. OVERALL THE LAB WAS. This lab test can be conducted for both undisturbed and remolded specimens.

Direct shear box apparatus Fig. Direct shear test is useful when cohesionless soil are to be tested. DIRECT SHEAR TEST OBJEVTIVES To determine the shear strength parameters for a given soil using the direct shear test.

Loading frame motor attached. View Lab 5pdf from CIVI 432 at Concordia University. Analysis of the results provides data for geotechnical engineers to calculate soil bearing capacity slope stability.

A direct shear test is a laboratory test used by geotechnical engineers to find the shear strength parameters of soil. The test utilizes the Direct Shear Box to test the soil then using the equation s the angle of friction can be determined. NMT Lab Direct Shear Test High Normal Load TEST NO.

INTRODUCTION The test is carried out on either undisturbed samples or remoulded samples. Assemble the shear box as indicated in. Compute 15 of the diameter in millimeters.

It is made up of basically the components Frictional due to friction between individual particles. The Direct Shear Test is an experimental procedure conducted in geotechnical engineering practice and research that aims to determine the shear strength of soil materials. The direct shear test measures the shear strength parameters which are the soil cohesion c and the angle of friction.

The size of the specimen generally used is about 20 to 25 cm2. Weigh the initial mass of soil in the pan. 3035469657 DEPT OF CIVIL ENGEINEERING THE UNIVERSITY OF HONG KONG 1.

MID-AAF-0002-2 Measured Cohesion Water Content Shear box size 508 Peak Shear Stress 16393224114855862736. Shear Test Experiment Lab Report. The laboratory report cover the laboratory procedures for determining these values for cohesionless soils.

To facilitate the remoulding purpose a soil sample may be compacted at optimum moisture content in a compaction mould. Shear strength is defined as the maximum resistance that a material can withstand when subjected to shearing. Preparation has proved that shearing device and test plate.

Direct Shear Test CIVE 334 Dr. The force on the specimen is applied from the top of the shear box. The result is obtained as per IS code.

The laboratory report cover the laboratory procedures for determining these values for cohesionless soils. KEY WORDS AND DOCUMENT ANALYSIS a. Lab Report 5 Direct Shear Test Monday 15st of November Mathias Girma 40078339 Section LR-X Table of.

This phenomenon in direct shear test lab report is no significant digits that is observed when testing time have been present an applied. Use the template provided to prepare your lab report for this experiment. The direct shear test is one of the oldest strength tests for soils.

NMT Soil Lab TEST DATE. The soil specimens may be square or circular. Nmt lab direct shear test high normal load.

Direct shear box apparatus. During the determination of soil shear strength in a laboratory by different test. Carefully assemble the shear box and place it in the direct shear device then place a porous stone and a filter paper in the shear box.

The direct shear apparatus. The procedure is cost-effective for characterizing basic soil properties. Measure the diameter and height of the shear box.

The strength of a soil depends of its resistance to shearing stresses. The direct shear test is one of the oldest strength tests for soils.
