摘要
对于排桩冻结法深大基坑,冻结作用使基坑的受力过程变得更为复杂,内支撑轴力的大小和变化与其他基坑也明显不同。本文根据润扬大桥南锚排桩冻结法深基坑的施工安全监测和监测数据的分析,初步掌握了排桩冻结法深基坑支撑轴力的大小、分布和变化规律。基于施工监测进行了反馈分析,保障了排桩冻结法深基坑的安全与稳定,也为今后类似工程的建设积累了经验。
Ground Freezing made the mechanic state of foundation pit become complex for ground freezing and pile-support deep foundation pit.The value and change of Inner-support Axle-force is different from other kind of foundation pit.This initial rules of value,distribution,and change of inner-support Axle-force for ground freezing and pile-support deep foundation pit of south anchorage of Runyang Bridge,based on construction monitoring and analysis of monitoring data.The safety and stability of ground freezing and pile-support deep foundation pit was enˉsured,and the experience was accumulated for the similar project in future,based on the feedback analysis of ground freezing and pile-support deep foundation pit of south anchorage of Runyang Bridge.
