1 ASCE Earth and Space Conference, 2016 Reporter： Institution: Date: 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component Outline Introduction The Establishment of the 3D Geospatial Function monitoring model The Solution of the 3D Geospatial Function monitoring model Case Study 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component Part1 Introduction 1 Introduction The monitoring model of arc dam deformation based on monitoring data provides basis for the evaluation of arc dam safety. In the traditional monitoring model of arc dam deformation, water level component, temperature component, and timelines component are used to reflect arc dam deformation as follows: Where is the water level component, is the temperature component, and is the timelines component. 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component 1 Introduction The water level component: Where is the coefficient of water level and is the water level. The timeliness component: Where and are the regression coefficients and is the time factor from the starting day to the analyzing day 1 Introduction 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component 1 Introduction 3D Geospatial Function Monitoring Model of Arc Dam Deformation Based on the Improvement of Temperature Component For the temperature component, it has two types: (1) Since the temperature change in arc dam lags behind the environmental temperature, and the temperature component has the linear relationship with the temperature of concrete. The linear combination of multi previous average temperature is used to show the temperatu
