1、摘要随高层/超高层建（构）筑物、地铁工程、大型管道工程等的出现，工程基坑的开挖深度不断加深、规模也愈来愈大，致使基坑安全问题成为我国工程建设事业当中最值得重视的方面之一。为保证在整个基坑工程期内所有环境设施的稳定性与安全性，必须在对基坑工程制定详细的监测方案后，进行严格有效的变形监测。本文内容共分为三章进行阐述，前两章是作为对后文的铺垫，主要是对基坑变形监测的知识要点进行一定概括简述。第三章为本文重点，以位于青岛市城阳区水岸豪庭基坑边坡变形监测项目为实例，对其制定完整具体的基坑变形监测方案设计，设计监测项目为基坑围护结构及其周围、地下环境设施，以达到及时向设计、施工、建设、监理等单位反馈监
