摘要
结合某地铁明挖车站深基坑土建工程,对深基坑墙顶水平位移、混凝土支撑轴力和周围建筑物沉降、地表沉降、管线沉降、地下水位进行半年跟踪监测分析。结果表明:各项的累计变化量和变化速度均在安全规定范围内,说明深基坑在施工过程中总体上处于安全状态且未对周围建筑物和管线造成危害。对地下水位超红色警戒值的险情采取有效地处理措施,监测结果表明所采取的处理措施效果明显。
In combination with the civil engineering of deeply open excavated foundation-pit of a subway station,half a year tracking and monitoring analysis have been made for the top horizontal displacement of deep excavation pit wall,the axial force of reinforced concrete supporting,settlement of surrounding buildings,ground surface settlement,pipes settlement and underground water level etc. The results show that,the cumulative variation and variation speed are within the scope of the safety regulations,indicating that the deep foundation pit is in safety state during construction process and does not cause harmful effects on the surrounding buildings and pipelines. Effective measures are taken to deal with the situation of underground water level over the alert value,and the monitoring results show that the treatment effect is remarkable.
