摘要
根据在浙江省慈溪市某静压法沉桩施工现场所监测的地基土位移数据,定量分析比较了控制施工进度、设置应力释放和排水深孔等工程技术措施对减轻饱和软粘土地基沉桩挤土效应的有效性,并初步提出了现场地基土位移及其变化速率的监控标准.对防范类似施工场地周围建(构)筑物遭受沉桩施工的有害影响具有实用参考价值.
Based on the data of vertical and horizontal displacements from a certain construction site in Cixi city of Zhejiang Province, the validity of controlling earth-extrusion effects in saturated soft clay ground caused by statically piling was quantitatively analyzed and compared with different technical measures, including reduction of piling rate and installation of stress-relax holes. A preliminary criterion on soil displacement was suggested, which is of use value for reference to eliminate harmful impacts of earth-extrusion effects on the surrounding engineering events at a geologically similar fields.
