摘要
对平姚某基坑土钉墙施工过程采取了有效的监测手段,通过对监测数据进行分析,及时发现了局部土体开裂,对裂缝产生的原因进行了分析并及时采取了设置拉结筋、加大注浆压力等有效的加固措施阻止了裂缝的发展,使位移收敛点在预期时间内。监测结果表明,基坑位移存在一定的滞后效应,监测工作应持续到结构稳定之后。
Effective monitoring measures are adopted in some soil nailing wall support engineering in Pingyao. Based on analysis of monitoring data, local soil crack is found in time and the reason is analyzed. Some measures as setting tie bars and increasing grouting pressure are taken to make displacement convergence point in expected time and prevent crack development. The monitoring results show that there is hysteresis effect in foundation excavation displacement and monitoring work should be kept on until the structure stable.
