The Study Of The Interaction Between Anchor Chain And The Foundation

With the land resource exhausting, people begin to seek for resources and energy from the ocean. Therefore, all kinds of marine engineering structure arise at the historic moment. But marine engineering will face complex sea conditions. So most marine engineerings will be anchored to anchor pile or suction anchor for increasing its stability. This paper will mainly study the anchorage foundation of deep sea platform.This paper will mainly discuss suction anchor and the anchor chain and the interaction between the anchored foundation with the marine soil. In china, south china sea contains a third of the oil and gas resources. The anchored foundation which this paper mainly discussed will be applied to south china sea.This paper will use the method of finite element simulation to study the anchored foundation. For the mechanical response of the embedded anchor chain, Degenkamp and Dutta carried out an experiment, they studied the load of unearthed end and the load of the anchored end. In addition, Neubecker and Randolph use the method of theoretical derivation to study the mechanical response of the embedded anchor chain Neubecker and Randolph used mechanical equilibrium equation to derivation the mechanical response of the anchor chain. For the finite element simulation method, this paper will firstly compare the data derived from the finite element simulation method with the related experimental data and the data from the theory calculation. Through the above steps, the finite element simulation method will be confirmed effective. Then this paper will use the method to study the anchored foundation with different parameters.Then this paper will study the engineering geological conditions of the south china sea and the properties of the the south china sea soil. Based on the above study, this paper will select the parameters of the marine soil. Then this paper will study the anchored foundation applied in south china sea using the finite element simulation method. This paper will mainly study the interaction between the anchor chain with the marine soil and the limit bearing capacity of the anchored foundation. At last hoping this paper will make some advantages to the related engineering.Above all this paper will firstly prove the finite element simulation method. Then this paper will study the selection method of the parameter of the south china sea soil. Next this paper will use the finite element simulation method to study anchored foundation applied in south china sea. At last, this paper will give some suggestion on the related researchs.
