摘要
文中结合实际工程,针对某半地下储罐基坑设计采用钻孔咬合灌注桩支护方案;在5#储罐基坑周围区域布设了多个监测点,监测地表沉降、桩顶沉降、桩顶水平位移、桩体水平位移、支护桩钢筋应力、圈梁轴力以及地下水位,根据监测数据分析支护结构的变形情况.结果表明,基坑在施工期间处于安全合理的受力状态,支护结构可以充分发挥控制基坑变形、保障基坑稳定的作用.
Abstract
Based on the actual project,the support scheme of the drilling occlusive pile is designed for the foundation pit of a semi-under-ground storage tank.Several monitoring points were placed around the fifth tank pit to monitor surface subsidence,pile top settlement,pile top horizontal displacement,pile horizontal displacement,support pile reinforcement stress,ring beam axial force and groundwater level.The de-formation of the support structure was analysed according to the monitoring data.The results showed that the foundation pit was in a safe and reasonable state of stress during the construction of the project.The support structure could give full play to the role of controlling the deforma-tion of the foundation pit and ensuring its stability of the foundation pit.
