中文摘要：

工程变形监测预警内容涵盖广泛,需要测绘、岩土、地质等各专业进行综合监测后,统筹各个监测内容所得到的数据及结论,进行变形分析和预警判断。为此,查阅有关变形监测预警的资料,研究轨道交通工程三级预警标准,初步建立一个可实现预警功能的变形监测物联网预警系统,并以高速铁路工后沉降监测为例,建立一个完善的运营期高速铁路沉降监测预警技术指标体系,对规范工程监测预警工作有实际意义。

英文摘要：

Projects deformation monitoring and warning includes wide contents.Thus the combination of survey, geotechnical,geological and other professional is required to conduct comprehensive monitoring,co -ordinate various monitoring data and conclusions.Then the deformation analysis and warning judgment can be achieved. Therefore,this paper looks over the information about deformation monitoring and warning and do some research on rail transit project about three warning standards.It can help to establish a deformation monitoring warning system based on Internet of things initially which enables warning function.Besides,research results establish a better high-speed rail post-construction subsidence monitoring and warning technology system as an example, which is meaningful to the standardization of similar projects.
