The Design And Implementation Of The Monitoring Data Management And Analysis System For The Displacement Of Deep Foundation Pits

In order to reduce the damage of urban deep foundation pit to the surrounding rock and soil environment,the deformation monitoring and prediction of urban deep foundation pit has become a necessary link in the design and construction of urban deep foundation pitinthecity.The management and analysis of monitoring data has become particularly important,and the traditional monitoring data management and analysis system gradually cannot meet the demand of reality in the work,how to manage and analyze the monitoring data in a unified and efficient way has become a problem that researchers urgently need to solve.On the basis of previous studies,this paper analyzes and discusses the monitoring methods,data management,data analysis and data forecasting of urban deep foundation pit displacement monitoring,and carries on the deep foundation pit displacement monitoring data management and analysis system was established based on the project need.The main research contents are as follows:First of all,according to the relevant monitoring technical specifications,the monitoring points arrangement,monitoring methods,monitoring accuracy,monitoring frequency,monitoring and warning value and alarm value of deep foundation pit displacement monitoring work are discussed and analyzed.Secondly,we analyzes the deformation monitoring of commonly used displacement prediction model,using polynomial regression model to simulate the engineering examplesand the displacement of foundation pit deformation prediction,proved that the polynomial regression prediction model has the ability to forecast the displacement and deformation of deep foundation pit.Finally,aiming at the problem that the spatial data and attribute data of deep foundation pit deformation monitoring can not be managed efficiently and uniformly,the unified management of attribute data and spatial data of deep foundation pit deformation monitoring under SQL Server2008 is realized based on Arc SDE spatial data engine technology.And based on Visual Studio 2010 development platform,we carries on the deep foundation pit displacement monitoring data management and analysis system development combining with Arc Engineand ADO.NET development technology,realize the automatic analysis of monitoring data,monitoring report is automatically generated,deformation curve automatically generated,displacement deformation prediction,etc.
