| The earthquake subsurface fluid observation plays significant part in the precursor observation of earthquake. The domestic enormous amount of research has shown that the gas of groundwater, including Radon, Helium, Hydrogen, Mercury, Hydrogen Sulfide, can reflect the earthquake precursor information accurately, and the Radon anomaly is widely claimed to be one of the 7 major earthquake precursors. In 1994, an 8.3-magnitude earthquake occurred on the southwest coast of Japan, and some scientists had observed the dramatic change of Radon concentration before the earthquake, which has sparked the study on the relationship between Radon concentration and earthquake. Thereafter, many countries such as the former Soviet Union, Japan, India, China, American, have accumulated a huge mass of data on Radon observation, earthquake and structural activities. The researchers usually make some comprehensive preparations for emergency rescue service, disaster prevention and mitigation, by summing up some empirical and statistical information of Radon anomaly.This thesis has analyzed connection of Radon anomaly, geological environment and the influencing factors of earthquake on Radon anomaly, manage the data of Radon anomaly, which is used to develop a set of system to store, analyze annual relevant data of Radon anomaly. It utilizes popular data Management system of B/S structure to combine the Radon anomaly and earthquake, which can provide scientific reference for earthquake research.The main contents and innovation of this thesis are as follows:(1) This thesis aims at analyzing the difficulties of Radon anomaly reflecting earthquake and the future trend of earthquake information network technology by investigating the relationship of Radon anomaly with earthquake and some domestic and foreign literatures about earthquake information network technology.(2)There are two types of changes about Radon anomaly reflecting earthquake by discussing the relationship of Radon anomaly and earthquake:the one is stageChange, the Other One Is Pulse-shaped Change. the System Is Designed to Get Effective Earthquake Precursor Information to Provide Some Help for the Study of Earthquake by Radon Anomaly. (3) Developing the System of Radon and Seismic Information Based on Web Platform. Firstly, the System Build System Software Environment by Using the Eclipse+Tomcat Development Platform Through System Requirement Analysis. Secondly, This Thesis Detailed Comparison of the Web Platform’s Design Framework Software Environment and Proposes System Architecture Using Spring Framework to Complete the Function of the System. Thirdly, It’s Also Designed the Interface Display Frame of Data Information of Combined with Jquery+Ajax. Fourthly, the Radon Concentration Data Curve Is Generate by Jfreechart, Meanwhile There Are Two Modules of the Document and System Management Added Upon the System. Finally, A Good Feasibility and Practicability of the System Was Achieved on the Basis of Improving the Security of the System. (4) in Order to Design the Database of the Earthquake Information and the Radon Concentration Data, the System Adopted Powerdesignerl6.5 to Establish Table Structures of Radon Concentration and Relationship Among Tables. Finally, the Users Can Analyze the Changes of Radon Concentration Before and After Earthquake from the System. |
