地下空间开发中变形监测的新技术

New techniques of deformation monitoring in underground space development

当前的地下空间开发强调信息化施工,在诸多施工监测内容中,结构与环境的变形监测是其中最重要的一项。结合具体的工程实例对差异沉降、地下连续墙的水平位移,以及隧道变形等监测新技术进行扼要介绍。工程实践表明,这些新技术具有精准度高、稳定性好、可以实现实时自动采集与数据的远程传输等共同特点,是未来变形监测的发展方向。

Observational construction is emphasized in current underground space development and deformation monitoring of underground structures and environmental protection are the most important items in monitoring. The paper briefly introduces the new monitoring technologies of settlement differences, horizontal displacements of diaphragm walls and tunnel convergences in accordance with concrete projects. Practice indicated that these new technologies have common features of high precision, good stability, automatic data acquisition and information transfer with interact, they highlight the prospect of underground space deformation monitoring.
