摘    要:张力腿平台是一种理想的深海开发平台.桶形基础是目前世界上新式基础形式,其适用的土质范围、水深范围及环境荷载均相当宽广.如果能将桶形基础应用于张力腿平台,则会使张力腿平台更加经济实用.实验中使用一种自主设计的桶形基础模型沉贯及抗拔实验仪器,进行相应的模型实验,以探索将桶形基础应用于张力腿平台的实用性.实验证明水头驱动力可以代替泵抽吸实现桶基沉贯,实验装置较好地模拟了张力腿受动载荷作用的工作情况,初步探求了动载荷对桶形基础的影响.

关 键 词:桶形基础  沉贯实验  抗拔实验

Abstract:Tension leg platform (TLP) is one of the most useful platforms in developing deep sea. And bucket founda- tion is a popular foundation form in the world, which can be widely applied to various fields such as soil condition, water depth and environmental loads. If bucket foundation is applied to TLP, then TLP can be more economical and practical. In this paper, in order to discuss the practicability of applying bucket foundation to TLP, an independently designed experimental apparatus was used in suction penetration and uplift behavior model experiment of bucket foundation. The experiment proves that water pressure driving force can replace pump to achieve the suction. And the apparatus well stimulates the condition in which TLP bears dynamic load well, which can search the influence ex- erted by dynamic load on the bucket foundation.
Keywords:bucket foundation  suction penetration experiment  uplift behavior experiment
