. In order to protect cast-in place piles of high speed railway bridge, steel pipes which used to be used during the work progress are left forever to increase the durability of concrete piles. The relative experiments are carried out indoor. On one hand, steel pipe can separate the concrete from exterior environment; on the other hand, under the condition of freezing, steel pipe can produce hoop effect to the concrete which can reduce crack expansion stress because of frost heave. Mass loss, relative dynamic modulus of elasticity and strength about steel pipe concrete are studied. The conclusion shows that the durability of concrete piles with steel pipe protection is much better than common concrete piles with no protection.
