Abstract:
Based on the design practice of foundation ditches in soft soil district and the concept of equivalent rigidity, one-row piles was used to simulate the retaining structure with space double-row layout dislocation PHC piles. The characteristics of internal force and lateral displacement of space double-row layout dislocation PHC piles were analyzed by FEM. The results show that the maximal bending moment of the one-row piles is nearly equal to the sum of the bending moment of the front piles and the bending moment of the back piles. The maximal displacement, the location of the maximal displacement, and the distributing form of displacement of the two retaining structures are all approximately sameness. The calculation accuracy can meet the design requirement. The method can simplify the calculation of the horizontal displacement and the bending moment in such structures while provide reference to the construction design of similar projects. 4 tabs, 15 figs, 10 refs.
