摘要
研究目的:通过对典型断面沉降变形观测数据的分析和工后沉降的经验预测,判断CFG桩地基处理形式在京津城际轨道交通北京段路基的工程效果,为今后相应的工程提供参考依据。研究结果:京津城际轨道交通北京段路基典型断面沉降变形观测数据的分析和预测表明,路基3个月沉降已趋于稳定,总沉降量和工后沉降量均能满足规范要求。但CFG桩地基处理形式的总体效果,需要对大量数据综合分析后才可能提出。
Research purposes:Through the analyses of the observed data of typical section subsidence and the prediction of post-construction subsidence,the evaluation is made for the engineering effects of treating the subgrade of Urban Mass Transit between Beijing and Tianjin with CFG pile for the purpose of providing reference basis to similar construction in future. Research results:The analyses of the observed data and prediction of typical section subsidence of the subgrade of Urban Mass Transit between Beijing a...
