Abstract: From the perspectives of reducing displacements of dry dock walls during the process of pit excavation, and controlling the seepage of dock walls in the course of using, the application of techniques of soil nailing wall and composite soil nailing wall widely used in deep excavation, the construction of dry dock by using numerical simulation are explored emphatically. FLAC is one of methods of numerical simulation, which is widelyused in rock-soil engineering field. The FLAC is used to simulate the working condition of soil nailing wall in pit excavation of dock chamber; and the application of stiffened cement soil mixing pile(SMW) prestressed anchor plus soil nail structure to dock walls is studied. According to the simulation results, some sconclusions at the construction of dry dock walls are drawn.

Key words: soil nailing wall, dry duck wall, FLAC, numerical simulation, prestressed anchor, SMW
