Abstract Abstract:Research purposes:In order to solve the high-speed railway settlement problem, this paper researches a Structure Settlement and Deformation Monitoring and Analysis Integrated System(SMAIS) for high-speed railway. The SMAIS system is composed of sensor subsystem, data collection transmission subsystem, data real-time tracking and remote query by client end subsystem, monitoring results post-processing subsystem, automatic early-warning subsystem, manual measurement data management subsystem and data analysis and evaluation subsystem. And the field experiments were successfully carried out in part location of Beijing-Tianjin inter-city railway project for long-term automatic monitoring by SMAIS.

Research conclusions：The engineering verification results show that: (1) The SMAIS integrated monitoring system has a good monitoring precision, higher stability and applicability for engineering structure settlement automatic monitoring of high-speed railway.(2) Data track and remote net dynamic query platform of SMAIS realize the automation, real-time transmission, visualization, remote query technique monitoring, automatic alert and generate report functions target, the large manpower has been saved. (3) The alert subsystem of SMAIS realize automatical alert and alert information analysis function, it provide a scientific guidance for construction and decision-making. (4)This system can be used in settlement monitoring of high-speed railway subgrade and bridge

Key words： Key words: high-speed railway engineering structure automatic monitoring settlement deformation evaluation analysis system integration
