Research on calculation method of retaining structure with double-row pile

摘要

As one of the optimum design of enclosure structures for deep excavation, the double-row pile has advantages of large lateral stiffness, no support and small footprint. But more studies should be done on how it works practically. the paper summarizes the currently used model, analyses and compares of their characteristics. Using a typical example, verifies the advantages and disadvantages of flexible calculation method, and directs the future study of double-row pile.
