- 摘要:
- 针对海上油田开发的特点,综合考虑初期投资、建造运营期的安全性、维修费用、耐疲劳及腐蚀性能、施工工期、施工难易程度和对环境的破坏程度等多项条件,建立了基于水深和地质条件的海洋平台多目标选型优化模型。针对我国近海油田开发的特点,将水深划分为6个深度区间,为每一深度区间提供备选的平台型式,同时将海底地质条件划分为4种类别。采用层次分析法来求解这一选型多目标优化模型。将水深、地质资料以及备选的平台型式提供给具有丰富设计和建造经验的专家,请他们根据文中建立的层次结构模型对备选平台方案进行评判。实例分析表明,利用该模型,可以选择出适合给定水深范围和海底地质条件的最佳平台型式,为海洋平台的初步设计和建造提供依据和参考。
The multi-objective lectotvpe optimization modei based on water depth and geological condition is presented for offshore platforms taking into account of multiple items such as the original investment, safety during construction and operation, maintenance cost, the ability of resisting fatigue and corrosion, construction period, threat to the environment, and so on. Aimed at the characteristics of our country oil field development, water depth is divided into 6 depth intervals and different platform alternatives are supplied to each interval. Simultaneously, the seabed condition is classified as 4 types. The Analytical Hierarchy Process (AHP) is ap-plied to solve the multi-objective lectotype optimization modei. Data about the water depth, geological condition and platform alternatives are provided for experts with abundant experience of design and construction, and they are required to make judgments according to the hierarchy structure model. Through the analysis of a practical instance with this modei, it can select the optimal platform type suitable for the specified water depth interval and geological condition and provide references for the primary design of offshore platforms.2003,5(5): 1-6 收稿日期：2003-4-29DOI：10.3969/j.issn.1001-2206.2001.03.001.分类号：P752基金项目：国家自然科学基金重大项目资助课题(编号59895410)作者简介：王立成(1975- ),男,山东省安丘市人,大连理工大学土木水利学院讲师,博士后,目前研究领域:海洋采油平台结构优化设计和海洋环境条件下混凝土结构基于耐久性的设计方法研究。参考文献：
