【 摘 要 】

With the construction of large bridges in the deep sea, people are paying more and more attention to stability of bridge piles. The deep sea-bridge could be affected by many factors, and the force mechanism is very complicated. In this paper, the Hong Kong Zhuhai Macao Bridge navigation hole steel composite pile is used as the prototype pier. We establish 1:7.33 scale model and the same proportion of RC pile by analysis software, and make a comparison under compression, bending and shear load. Analysis results shows that pipe can improve the mechanical properties of core concrete and reduce the displacement of structure. The seismic response time history analysis of two kinds of structure shows that steel composite pile has larger lateral stiffness, smaller lateral displacement and better seismic performance.
