摘要
针对上海某油罐地基地质情况与处理要求进行了各种方案分析与比选,在此基础上给出了高真空击密+充水预压的设计方案,对高真空击密法处理效果进行了静力触探试验检测,结果显示地表下3.0 m厚度内粉质粘土与粘质粉土加固效果比较明显,满足了第一步处理要求;而随后的充水预压将地基承载力进一步提高到设计要求。该工程表明高真空击密法与充水预压对于油罐地基处理有一定的优势与便利性。
According to conditions of the ground around oil tank foundation in Shanghai and treatment demands, all sorts of treatment are compared and analyzed and then layout of high vacuum compact method and reloading method with water is proposed. Effect of high vacuum compact method on ground treatment is tested by static penetration test. It shows silty clay with the thickness of 3 m below the ground surface and clay silty effective. Subsequently,preloading with water can augment the ground capability to reach its needs. This project shows HVCM and preloading method with water have advantages on ground treatment.
