As a new kind of pipe pile

the cast-in-place concrete thin-wall pipe pile

referred to as PCC pile

with a large diameter

has been used in many engineerings to improve the soft ground; but the bearing capacity under lateral load hasn’t been studied well. Through the in situ test

the authors analyze the horizontal bearing capacity

the pile displacement and the soil pressure around the pile under lateral load. In addition

the effect of the repetitious loading pattern on the pile-soil interaction is also given. All tests show that the PCC pile can be provided with preferable horizontal bearing capacity; and the force act on the PCC pile mainly fast on the upper part; at last

the analysis also shows that the one-way cyclic loading has much effects on pile lateral capacity and the nonlinearity of pile soil interaction.
