摘要：

Soil, structural and wave measurements are recorded on FRIGG CDP 1, a concrete gravity platform of Doris-Howard design. The soil and structure responses are analyzed for various sea states, defined by significant wave heights and wave directions. Computer processing of digitally acquired data, in the time and frequency domains shows how wave energy is transferred to the structure and correlates pore pressure in the soil under the structure to the sea state. Several soil-platform modes have been identified in the 0-1 Hz frequency band width. Differences exist between dynamic behaviors of this type of gravity platform and a conventional steel jacket.
