对于100 m水深的大型导管架综合性平台，在结构形式上，可以采用不同的设计方案，在水平层上可以采用5层或6层布置。为了论证两种方案的优劣，此文运用相同的环境数据，运用SACS有限元软件，论证了两种结构形式的可行性，对两种方案进行施工受力分析，对比两种导管架平台方案所受环境荷载、桩头力、导管架节点数量、结构重量等关键参数，最后论证了两种导管架方案中5层方案是用钢量少，受力特性优，投资较低的结构方案。

Different structure layout scheme can be applied to the large comprehensive jacket platforms with water depth of 100 meters. On the horizon level, five or six floors can either satisfy the requirements. In order to check out which scheme is better, the feasibility of two structural forms was demonstrated with the same environmental data and SACS finite element analysis software. Construction stress analysis of the two schemes was performed by contrasting different environmental loads, pile head forces, numbers of tubular joints, structural weights and other critical parameters. The results show that five-floor scheme is better at the amount of steel, force characteristics and the investment.
