摘要
地基处理是大型油罐建设的重要环节,介绍了某软土地区大型油罐地基的处理效果,基于沉降观测数据,分析了充水预压期间油罐环基和罐中心的沉降特性;采用泊松法预测了环基总沉降,探讨了油罐地基的平面倾斜、非平面倾斜及罐基拱度特性,分析结果为该油罐地基的纠偏加固提供了依据。
Foundation treatment is an important link for large oil tank engineering. It is introduced the treatment effectiveness of 50 000 m^3 oil tank foundation, which sits on soft soil and improved with stone columns. Based on the testing settlement data, settlement properties of ring wall foundation and oil tank center foundation are individually discussed during filling water preload, and Poison method is used to forecast the ultimate settlement of the ring wall foundation. Nonhomogeneos deformation at the end of water filling preload is also analyzed. All conclusions will provide a basis for the reinforcement of the oil tank foundation.
