Gokongwei College of Engineering Civil Engineering Department Experiment No. 1 Vane Shear Test in Cohesive Soil Submitted by: Dela Peña‚ Analyn A. 10948724 LBYCVG2 EJ Submitted to: Engr. Irene Ubay Professor Submitted on: October 8‚ 2012 I. Introduction 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

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 cylinder. The various sizes of the vanes are accounted for by applying the multiplying factor. The value obtained from the medium sized vane is the value of the stress itself‚ and there is no need to multiply or divide the value. The values

Direct Shear Box Test Contents Introduction Objective Apparatus Description of Test Results Calculations Relevance to Geotechnics Soil Description and Conclusion References Introduction Shear strength is the property that enables a material to remain in equilibrium when its surface is not level. (Smith‚ 2006) The direct shear test is used to determine the shear strength of soils on a predetermined failure surface. This test is used to measure the shearing resistance‚ undrained shear

EFFECT OF JOINT ROUGHNESS ON SHEAR STRENGTH OF JOINT IN GRANITE Introduction Shear strength is the extreme shear strength where a material can support before rapture. Based on Lama and Vutukuri (1978)[1]‚ it is one of the critical aspects used for designing purpose. There is no doubt that joint is a main factor that leads to failure in every rocks type including granite. In granite‚ shear strength is one of the main characteristic that needs to be determined in order to classify its strength and

Stress is something that has become prevalent in our society‚ more so now than ever before. Demands from everyday life have certainly increased‚ creating more stress in our lives and potentially affecting our health and wellbeing. The purpose of this essay is to discuss stress and the effects it can have on our behavioural responses. Firstly‚ it will give an overview of stress‚ as well as discuss physical and mental concerns bought about by excessive stress and factors that contribute towards it

In the present day‚ stress is widely recognized as a major problem for many employees in their daily life. According to Lawrence（2010）：The Health and Safety Executive (HSE) have defined stress as the adverse reaction people have to excessive pressure or other types of demand placed on them at work. This definition suggests that when people experience excessive stress‚ there is a high risk. And this phenomenon also contributes to some bad consequences‚ such as mental illness，heart and circulatory

Stress has many interpretations and carries a negative connotation for most people. Over the years‚ stress has been indentified in different ways. It was conceived of as pressure from the environment‚ then as strain within the person. Today‚ stress can be known as the interaction between the situation and the person. It is the psychological and physical state that results when the resources of the person are not sufficient to cope with the demands and the pressure of the situation. Stress can undermine
