Experimental study on squeezed branch pile foundation in soft soil ground

The squeezed branch pile has the virtues of high bearing capacity, low settlement and simple machinery. With regard to soft soil foundation in the littoral of China, the vertical compressive, vertical pulling and horizontal static load tests are carried out to obtain the ultimate bearing capacity under various working conditions. By testing the internal force of piles, the distribution law of the axial force is obtained, and the load transfer mechanism and bearing capacity are studied. Based on the test results, the squeezed branch pile has obvious advantages in bearing capacity compared with the conventional piles.
