分析了内陆地区抗浮和防水设计水位的选取方法,以冀东南堡油田2#人工岛工程钻井放喷池抗浮和防水设计水位选取实例,提出了海洋人工岛抗浮和防水设计水位选取方法,并对其影响因素进行了分析。对于人工岛永久性构筑物,抗浮设防水位按岛面高程选取;而临时建筑物或施工期建筑物,可取岛面高程以下0.5～1.0 m。影响抗浮、防水设计水位的主要因素为人工岛的高程和降雨。
This paper analyzes the selection method of anti-floating and water-proof design water level in inland areas. Taking the examples of anti-floating and waterproofing water level selection in No.2 man-made island project of Jidongnanpu Oilfield, the design of anti-floating and waterproof design water level of marine artificial island Method, and its influencing factors were analyzed. For permanent structure of artificial island, the anti-floating waterproofing level should be selected according to the elevation of the island; and the temporary building or construction period should be 0.5 ~ 1.0 m below the island elevation. Affect anti-floating, waterproof design of the main factors for the artificial island elevation and rainfall.
