摘要
以合肥市某深基坑工程为研究对象,设计逆作法基坑支护方案,运用双排桩模型对方案中的双排桩进行计算。对支护结构中的围护桩所受内力及基坑支护方案稳定性进行验算,并与现场实际监测数据进行对比,结果表明,该基坑支护设计方案有效减少了土体变形和邻近建筑物沉降,取得了良好效果。
Taking a deep foundation excavation project in Hefei as the research object,the top-down method of foundation excavation support scheme is designed.The double row pile model is used to calculate the double row piles in this scheme.The internal force of the retaining pile in the support structure and the stability of the foundation excavation support scheme are checked and compared with the field actual monitoring data.The results show that the support design scheme effectively reduces the soil deformation and the settlement of adjacent buildings,and achieves good results.
