The Stress Formula of Soil under Vertical Line Load

Using integral method, the stress formula of soil for arbitrary Poisson's ratio under vertical line load was detailedly and completely derived based on Melan integral. The result shows that when the line load acting on the ground surface for arbitrary Poisson's ratio of soil, the stress formula is equivalent to the formula for Poisson's ratio of 0.5. Owing to such stress bubble graphics haven't appeared in Chinese soil mechanics textbooks, we give a detailed mapping of stress bulbs under vertical liner load.
