Jacket is an important part of a jacket wharf structure. Through physical model test research on jacket wharf stability under the wave action during construction，the cable dragging force during transportation，stability and anchor line tension on floating, and the lifting line force on hoisting are given. The results can be regarded as the scientific basis for the construction technology for jacket on different construction stages of towing，floating and hoisting. As the references for the jacket structure，it can also be wildly used in wharf engineering in our country.
