为了解永久船闸直立坡顶锁口锚杆应力状态,有效地评价锚固施工质量及锚固效果,在部分锁 口锚杆上布置了锚杆应力计,并进行了应力监测。监测成果表明,锚杆锚固效果明显,永久船 闸二期开挖完毕后直立坡变形基本趋于稳定。

For understanding the stress state of locked anchorbars at the top of TGP perm anent lock's vertical slope,and effectively evaluating their construction quali ties and anchoring effects,several anchor stress meters were located at partial locked anchorbars,and monitoring were practised. The monitoring results of str esses measured from anchorbars showed that anchoring effects of anchorbars a re obvious,the deformation of permanent lock's vertical slope basically tends t owards stability
