Title Correlation Analysis of Land Subsidence and Groundwater Level
Dept Transportation Technology Research Center
Year 2020
Month 2
Price 100
Summary       For the purpose of disaster prevention and emergency response, as well as preventing damage to various facilities in the port area due to land subsidence, we have set up monitoring stations in the four places which are Taichung Port, Budai Port, Anping Port and Dapeng Bay to collect long-term data on land subsidence and groundwater levels. The Institute of Transportation used to develop a prediction model for land subsidence simulation based on the coupled consolidation theory and one-dimensional consolidation theory in soil mechanics. In the construction model, a large amount of manpower and funds were required to measure the parameters of soil samples, while under the condition of limited manpower and funds, this study attempted to use regression analysis to develop a regression model barely based on soil mechanics theory and the existing monitoring data of land subsidence possessed by the Institute, with a view to explaining the correlation between the land subsidence and the groundwater level in the port area, as well as predicting the development trend of the land subsidence in the future. However, since the regression models of local stations have not passed the verification, it is advised that the correlation of each variable and the correlation of groundwater levels in each layer should be checked, and the appropriate variables should be selected again to establish the model, thereby proceeding with the tests of significance, goodness of fit and validity of each model in regular order.
Benefits and Applications:
       Test the use of regression analysis to develop regression models barely based on soil mechanics theory and the existing monitoring data of land subsidence possessed by the Institute to explain the correlation between land subsidence and groundwater levels in the port area. It can be used as a preliminary study for the re-establishment of a regression model of land subsidence in the future.
      It provides the Ministry of Transportation and Communications, the Maritime Port Bureau and the Ports Corporation with a reference for the analysis of development trend of land subsidence in each port area. It can be used as a reference for the follow-up discussion and application of related research such as land subsidence and disaster prevention in the port area.
