| This paper introduces a pre-stressed concrete special shaped pile which is called pre-stressed concrete bamboo-shape pile. The main differences between the pipe pile and pre-stressed concrete bamboo-shape pile has be expounded from the three aspects: shape, mode of pile extension and connection mode of bearing platform and pile. In addition, ultimate uplift bearing capacity of pipe pile and pre-stressed concrete bamboo-shape pile has been studied basing on the anti-pulling test which is conducted in Hangzhou. Comparing the ultimate uplift bearing capacity of two piles, the research shows that the anti-pulling behavior of bamboo-shape pile is better than that of pipe pile, and the ultimate uplift bearing capacity has been increased about fifty-two percent. Under the same load, uplifting displacement of bamboo-shape pile is less than that of pipe pile. The pre-stressed concrete bamboo-shape pile which is applied in anti-pulling project in Hangzhou has acquired a great of achievements.
