Construction technology of TC piles and its engineering application

The rigid pile composite foundation has been widely applied in soft ground treatment in recent years. The piled embankment system of TC piles, which belong to the rigid pile composite foundation, is introduced. It has been applied in some soft ground treatment of embankment for its advantages of better stabilizing effect, short construction period, better quality, economy, etc. Based on introducing the construction technology of TC piles and its application in a road engineering, the results of static load tests and deflection tests are analyzed. It is shown that the application of TC piles is feasible. It may provide reference for the theoretical researches on TC piles and composite foundations.
