为掌握和了解地铁基坑和隧道施工期间的支护结构和受力情况以及邻近建构筑物的变形情况,保证地铁基坑和隧道施工期间基坑支护结构和周围建构筑物的安全,为施工开展提供及时的反馈信息,需对地铁基坑施工期间进行监测。本文以某地铁站施工为例,介绍其施工期监测。
In order to grasp and understand the supporting structure and stress situation during the construction of subway foundation pit and tunnel as well as the deformation of adjacent structures and ensure the safety of foundation pit supporting structures and surrounding structures during the construction of subway foundation pit and tunnel, To provide timely feedback, it is necessary to monitor the subway pit during construction. This article takes a subway station construction as an example, introduces its construction period monitoring.
