摘　　要：北京城市副中心综合交通枢纽工程深基坑地质条件差、承压水头高、基坑周边受力情况复杂。深基坑开挖不仅是对其支护体系的极大考验,而且还会导致基坑周边地面的不均匀沉降,从而破坏周边环境。在基坑开挖过程中,需对支护体系进行全过程监测,以保证基坑的开挖施工安全及周边环境的稳定性,其可为实际工程的开展提供类似工程参考。The geological condition of the deep foundation pit of the comprehensive traffic hub project in the sub-center of Beijing city is poor,high pressure head,the stress around foundation pit is complex.the excavation of deep foundation pit is not only a great test to its supporting system,and it will lead to uneven settlement of the ground around the foundation pit.Thereby causing the destruction of the surrounding environment.During the excavation of the foundation pit,monitoring the whole process of the support system,to guard against microcosm,to ensure the safety of foundation pit excavation and the stability of the surrounding environment,to provide similar engineering reference for the actual project development.
