Webcreep, in geology, slow downslope movement of particles that occurs on every slope covered with loose, weathered material. Even soil covered … WebExcessive/wrong application of fertilizer may affect the soil pH making it too acidic interfering with soil micro-organisms. Leaching due heavy rainfall can lead to percolation of soil nutrients to the lower horizons leading to deficiency of the top soil. Excessive drought leads to accumulation of salts in the top soil making it saline.
WebCreep, which generally only affects the upper several centimeters of loose material, is typically a very slow flow, but in some cases, sliding may occur. Creep can be facilitated by freezing and thawing because particles are lifted perpendicular to the surface by the growth of ice crystals within the soil, and then let down vertically by gravity when the ice melts. WebJun 23, 2024 · A creep model for pile-frozen soil/ice interfaces was proposed based on a series of multistage creep tests. The test results show that the creep behavior of the pile-frozen soil/ice interfaces is easily observed at a steady rate larger than 0 even at a small load level, which increases as the increase of load level. The elastic shear modulus ...
