Effective cohesion of a soil can never have a negative value.<\/p>\n<p>Cohesion is the property of a soil that causes it to stick together. It is caused by the attraction between the particles of the soil. The effective cohesion of a soil is the cohesion that remains after the water has been drained from the soil. The effective cohesion of a soil can be negative if the water pressure in the soil is greater than the effective stress.<\/p>\n<p>The effective angle of internal friction is the angle between the major principal stress and the direction of the shear stress at failure. It is a measure of the resistance of a soil to shearing. The effective angle of internal friction is affected by the type of soil, the state of compaction, and the mineralogy and clay size content of the soil.<\/p>\n<p>The effective angle of internal friction for coarse grained soils is rarely below 30\u00c2\u00b0. This is because coarse grained soils have a high degree of interlocking between the particles. This interlocking makes it difficult for the particles to slide past each other, and so the soil has a <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> high resistance to shearing.<\/p>\n<p>The effective angle of internal friction for a soil increases as state of compactness increases.
