Research And Development On The Database System Of Subway Construction Deformation Monitoring

With the rapid development of social economy and technology, the rate of subway construction appears to be accelerating. In order to ensure construction quality, one of the most important jobs is construction monitoring, which has been widely applied. As the development of digit technology, Digital Information System has far-reaching effects on the original design patterns, detection and inspection technique in the civil engineering.Analyzing and forecasting the trend of deformation for underground projects and building (structure) scientifically, timely and accurately, which contributed to recognition deformation of retaining structures and adjacent ground, which can feed back information to guide the construction.So, it is extremely significant to analyze and store on-site monitoring data in time during subway construction.It is because the subway monitoring is a huge amount of data and the analytical method of monitoring data management adopts traditional document management mode which data computation and report management are both done by manual work.That is a heavy, and high repetitive work, which leads to inefficiencies and be problematic.In addition, the traditional mode can’t display the data conveniently and feedback information timely, so that it fail to issue early-warning and forecast timely and accurate and perform comprehensive analysis and judgmenteffectively.The purpose of this paper is to establish a complete Deformation Monitoring Data Analysis Management System in subway construction, which mainly contains four functions as the following:①mporting, storing, managing and analyzing monitoring data in bulk;②enerating reports, deformation time-history curves, section settlement curve, stress time-history curves etc automatically;③orecasting the deformation by using different linear regression analysis;④mplementingsecurity early warning, projecting statistics and supporting functions.In the last, based on the first phase of Beijing Metro Line6, this paper introduced this system in practical engineering application.
