摘　　要：为研究深基坑工程开挖过程对周边环境的影响,根据某深基坑工程的实际情况,通过对基坑工程圈梁及周边房屋道路的变形监测,支撑轴力和地下水位的监测,得到了基坑支护结构的变形规律及受力特点,以及基坑开挖过程中对周边道路、房屋环境的影响规律,为保证基坑工程施工的工程安全与稳定,控制基坑开挖对周边环境的影响提供了参考.结果表明,监测是基坑信息化施工的关键,基坑开挖到一定深度应及时完成支撑架设,温度对支撑轴力影响很大.The influences of excavation of deep foundation pits on the surrounding environment were studied.Based on the actual situation of an excavation example,the deformation rules and stress characteristics of the support structures as well as the influences on the nearby roads,houses and environment during its excavation were obtained by monitoring the deformation of ring beams and surrounding houses and roads and the support axial forces and the groundwater levels.It would be helpful to ensure the safety and stability of the excavation construction and to control the influences of the excavation on the surrounding environment.The results show that the monitoring is the key to information-based construction of foundation pits.When the excavation depth reaches certain value,the support should be completed in time.The influences of the temperature on the support axial forces are large.

关 键 词：深基坑开挖 变形监测 周边环境 地下水位
