gravity platform

Many series of platforms have been developed in recent years, such as gravity platform, jacket platform, self-elevation platform and tension leg platform, etc., to meet different geologic and marine conditions.

为了适应各种不同的油田地质状况和海况条件，开发了各种不同结构形式的海洋平台，如导管架式平台、重力式平台、自升式平台以及张力腿平台等。

Model a physical model of gravity platform as 1/ 25 of the real model. Simulate the environment of marine, and research the stability of the foundation under alternating load which is different by the oil volume.

交变载荷作用下的地基稳定性分析：对重力式平台进行物理模型实验研究，按照1：25的比例制作平台的工作模型，模拟实际海洋环境，研究储油量的交替变化对地基稳定性的影响。
