Bearing behavior of a new type of prestressed pipe pile with rib
摘要
Abstract
The bearing behavior of a new type of prestressed pipe pile with rib (the pile with rib for short) via ABAQUS finite element simulation and in-situ static load test. The comparison between the in-situ static load test of the pile with rib and the common pile with the same outer diameter (S00 mm) shows that the ultimate bearing capacity of the piles with rib is 13.10% higher than that of the common piles. The influence of the pile parameters, including the thickness of the rib and the spacing between ribs, on the bearing capacity of the pile with rib is studied. Moreover, the design formula for bearing capacity of the pile with rib is suggested. The formula will provide an important reference for the large scale application of the new type of prestressed pipe pile with rib.关键词
