海外工程选址中的地质分析

Geologic analysis of site selection for overseas project

介绍在伊朗某大型LNG液化厂工程建设场地选址中,应用地质分析结合经济分析对比快速选出最优场址的过程。通过收集拟选定的A、B场址的已有地质资料,结合现场地质调查,得出各拟选场址的地质特点,认为场地中砂、钙质胶结和暗礁等对场地平整、地基处理、桩基及沉桩工艺、航道开挖、主码头建设、电厂和液化厂动力基础等影响重大,是影响工程造价的核心。通过对比,得出B地块是最优的场址的结论。

This article describes the application of geologic analysis and combinative economic analysis to select the optimal site for a LNG plant in Iran. Collecting the geologic data of the intended site A ＆ B, combined with field geological survey, we extract the geologic features of the site to be selected, and know that the sand, calcareous cementation and submerged reef are key influential factors for the flat land site, foundation treatment, pile foundation and pile driving process, channel excavation, construction of the main terminal, power plant and liquefaction plant base, and are the core influencing the engineering cost. The conclusion is drawn that site B is the best one.
