摘要
综合考虑基坑周围环境、工程地质条件及水文地质条件,对广州某基坑采用悬臂钻孔灌注桩支护结构。根据有关规范并结合基坑特点制定了基坑监测方案,并对基坑顶部水平位移、基坑顶部沉降、支护结构测斜、周边地表竖向位移、地下水位的监测结果进行了分析。结果表明,基坑变形存在一定的规律性,针对这些规律及时完善施工方案,确保了基坑和周围环境的安全。
Cantilever bored piles were adopted as the supporting structures in a foundation pit of Guangzhou by consider-ing the surrounding environment ,geological and hydrological conditions .The monitoring plan was scheduled according to the specifications and characteristics of the foundation .And then the monitoring data of the horizontal displacement of the top of pile ,settlements of the pile block ,inclination measurement of the supporting structure ,vertical settlements of the surrounding ground surface ,and underground water levels were annalysed .The results suggest that the deformation of the foundation pit has a certain regularity ,therefore the construction plan should be improved correspondingly to ensure the safety of the foundation pit and surrounding environment .
