Sandy soil liquefaction and water feeding method and device used for pile soil interaction shaking table test
The invention relates to a sandy soil liquefaction and water feeding method and device used for a pile soil interaction shaking table test. The method comprises the following steps: 1, a steel box is provided, a pile is vertically arranged at the center of the inner cavity of the steel box; 2, at least one hard water inlet pipe is vertically fixed to the inner wall of the steel box; 3, at least one sandy soil layer and at least one clay layer are sequentially contained in the steel box from bottom to top, corresponding water outlet hoses are horizontally laid at the predetermined height positions in all sandy soil layers during containing, meanwhile the water inlet ends of the water outlet hoses of all layers are connected with the lower end of the corresponding hard water inlet pipes, a plurality of small water outlet holes are evenly formed in the peripheral sides of the water outlet hoses to achieve fixed-point sandy soil liquefaction; 4, the upper ends of the hard water inlet pipes are connected to corresponding water inlet hoses, and water meters are installed on the water inlet hoses to achieve quantitative water feeding. By means of the sandy soil liquefaction and water feeding method and device, quantitative water feeding and liquefaction of predetermined sandy soil layers are achieved, operating difficulty is reduced, experiment cost is reduced, and the accuracy of sandy soil water content situation of a sandy soil liquefaction test is improved.
