| description | To study the improvement of pile bearing capacity and soil shear strength under the condition of vertical electroosmosis, the mucky soft soil is taken as the test object, and the vertical electroosmosis model test is conducted from top to bottom and from bottom to top. The shear strength test is conducted on the soil around the pile before and after the electroosmosis by observing the water content, soil surface settlement, soil current, soil pressure at the bottom of the pile, and other parameters; The static load test is carried out on the pile after electroosmosis and compared with the control group to study the static characteristics of pile-soil interaction under vertical electroosmosis. It is found that the ultimate bearing capacity of the # 1 side pile and the # 3 central pile has been increased by 3.7 times and 4.5 times, respectively, after electroosmosis, and the ultimate bearing capacity of the # 3 central pile is higher than that of the # 1 side pile, with an increase of 7.7%–9.2%. The effect of forward electroosmosis is better. Compared with reverse electroosmosis, the ultimate bearing capacity of the # 1 side pile and the # 3 center pile is increased by 18.5% and 16.8%, respectively. |
