为了掌握位山穿黄探洞应急加固工程大堤的工作状态,确保位山险工段大堤安全运行,2000年1～3月在大堤上安装埋设了监测仪器,并按设计要求的方法和频次进行了观测。经分析,得出以下几点结论:黄河大堤位移较小,主要是自然沉降和降雨导致,与洞内施工无明显相关性;大堤渗压主要受黄河水位影响,与洞内涌水、灌浆相关性不明显;洞内施工未引起大堤变形。
In order to grasp the working status of the Embankment of Bitangshan Yellow Caverns Emergency Reinforcement Project and ensure the safe operation of the Dyke of the Bit Shanhan section, the monitoring instruments were installed and installed on the levee from January to March in 2000 and observed according to the design requirements and methods . The analysis shows that the displacement of the Yellow River embankment is small, mainly caused by natural subsidence and rainfall, and has no obvious correlation with the tunnel construction. The seepage pressure of the dike is mainly affected by the water level of the Yellow River, Not obvious; the construction did not cause the embankment deformation.
