【摘要】 根据油罐地质特点 ,对 5万m3 钢储油罐的四种备选地基基础方案 ,建立评价指标和层次关系 ,运用层次分析法优选出低强度混凝土刚性桩复合地基处理方案。该方法定性与定量相结合 ,较大程度地克服了方案选择的盲目性。实践证明低强度混凝土刚性桩复合地基投资少、工期短、受环境和气候影响小、安全可靠 ,适合油罐的地质条件。更多还原

【Abstract】 According to the geological characteristics,the evaluation targets and hierarchy relations of four types of foundation schemes of the 50,000m 3 steel oil tank have been established.Rigid pile composite foundation is adopted from the four by optimization with applying analytic hierarchy process.The low stregth concrete rigid pile base is proved to have the advantages of low cost,short construction period,less influence of enviornment and safty.更多还原
