| 摘 要： | 近几年基坑支护深度H不断增加,施工周期也不断变长,在北方一些寒冷地区,一些基坑工程不得不进入越冬期.由于基坑渗水和地下水的影响,基坑土体的冬季冻胀和春季融陷容易对支护结构产生一些不良作用.针对包头某越冬基坑进行了监测,总结了桩锚支护结构在越冬时锚杆轴力变化和基坑位移变化,并提出了一些防治冻胀的措施,为类似工程提供参考.

| Abstract: | In recent years,in certain northern cold areas, some projects of foundation pit engineering have to enter the winter season be- cause of the increasing excavation depth and the Longer construction cycles. Based on the influence of foundation pit on seepage and groundwater, the frost heaving and the thawing of the foundation pit soil filling may easily produce some adverse effects on the supporting structure. The monitoring of a winter in Baotou foundation pit was summarized about the variation of anchor axial force and the changes in the displacement of foundation pit anchor supporting structure in the winter, and a reference was offered for the similar engineering. |
