锚拉新技术在基坑再支护工程中的应用

On application of anchor bar technique in resupport project of foundation pit

论述了在已有的悬臂桩支护的基础上,进行锚杆再支护时,首次将第一道锚杆用一道钢筋拉杆代替,通过该道拉杆将整个被支护边坡和上部建筑结构联合成为一个整体,经过实际的位移观测和分析,证明该新技术是切实可行的,并且在桩锚支护的基础上又降低了成本。

Based on the existing cantilever pile support,the paper adopts the reinforcing bar pile at the first anchor bar in the anchor bar re-sup-port,integrates the support slope and upper architectural structure with the bar pile into the whole,and proves the new technique is feasible ac-cording to the factual displacement observation and analysis,so as to lower the cost based on the pile anchor support.
