The fully covered platform method and the artificial foundation bed method are often used in the construction of bored piles without overburden，but there are some problems such as high cost and low efficiency. Aiming at these problems，we rely on Hubco coal wharf project in Pakistan，propose an integrated construction technology of bored pile based on the incremental launching platform supported on pile top，realize high efficient construction of bored piles in severe sea conditions and without overburden，apply ANSYS to analyze the whole construction process of the incremental launching platform，and study the key control parameters and calculation methods of the construction process. The results show that the structural strength and stiffness of incremental launching platform supported on pile top can meet the requirement under different load and working conditions. It provides a reliable mobile platform foundation for integrated construction technology of bored pile.
