The calculation of anti-overturning stability is an important part in the structure design of gravity caisson wharf.The method of uniform design is used for the sensitivity analysis of anti-overturning stability of gravity caisson type wharfs,which can effectively reduce the test times and improve the test effectiveness.As a case study,the sensitivity analysis of a caisson gravity wharf in Quanzhou is carried out with selecting four factors including the wave height,angle of internal friction of the backfill rubble,gantry crane load on wharf and the width of a caisson.It is found that for common forms of gravity caisson wharf,the angle of internal friction of the backfill rubble and the width of a caisson are the most sensitive factors,while the gantry crane load on wharf and wave height are less sensitive factors.
