【摘要】 目前软土地基疏桩基础沉降计算方法尚不成熟,现行规范(JGJ 94-2008)对同时满足"桩中心距大于6倍桩径"的"软土地基减沉复合疏桩基础"的沉降应如何计算未作明确说明。根据连云港市云台变电所加固工程的数据进行理论分析并与实测沉降对比,得出以上情况宜按"桩中心距大于6倍桩径"公式进行沉降计算的结论,可为类似工程的设计提供参考。更多还原

【Abstract】 At present,calculation of creep pile foundation settlement in soft clay ground has been far from mature.The settlement calculating method is not clearly stated in the current norms(JGJ 94-2008),especially when the "pile center distance is greater than six times of the pile’s diameter" and "the piled raft foundation in soft ground".Based on an analysis and a comparative study of the data in Yuntai Substation Reinforcement Works,this paper comes to the conclusion that settlement calculation should be made by the equation that the center pile diameter is greater than six times of the pile’s diameter.Such a study can provide references for similar project design.更多还原
