Abstract: In this paper, three-dimensional integration framework of landslide monitoring data was proposed in the idea of mineral point-source information system and the WebGIS technology based on ActiveX. Seamless integration of data related to landslide monitoring,such as basic geographic data, geological survey data and sensor data was realized. In this process, program algorithm automatically handled method and visual interpretation in three-dimensional environment were used to improve the accuracy of landslide monitoring data. Furthermore，the suitability of landslide monitoring database was improved by separating landslide monitoring data from prediction mathematical model. All this provides the excellent basis for the stability evaluation and forecast of landslide. The monitoringproject of HuangTuPo landslide in Three Gorges Reservoir of China was taken as example to verify feasibility of the method.

Abstract: China has Suffered from the Landslide a Lot, which Mainly are Large and Giant Slope Slide. in the South-West of China and Three Gorges Reservoir Region, Landslide has Caused Great Lost to the People's Production and Living.Thus,building the Efficient Landslide Monitoring System is Not only Beneficial to Avoid the Occurrences of Landslide by Engineering Method, but also could Reduce the Lost Caused by Landslide. at Present, China Landslide Monitoring has Reached the International Advanced Level. the Monitoring has Large Monitoring Range with Various Methods. in this Paper, the Landslide Monitoring Method has been Classified by the Aspects of Monitoring Means and Monitoring Objects. According to the Difference of Monitoring Means, the Various Landslide Monitoring Methods could be Divided into Five Different Kinds, such as Macroscopic Geological Observation Method, Simple Monitoring Method, Setting-Station Monitoring Method, Instrument Monitoring Method and Auto-Telemeter Method.Meanwhile,basing on the Difference of the Monitoring Objects, the Landslide Monitoring could be Divided into 5 Categories, which are Deformation Monitoring,earthquake Sound Monitoring, Strain Monitoring,hydrographic Monitoring,environmental Factors Monitoring and Etc.It Provides Certain Reference Significance for the Selection of Landslide Monitoring Means According to the Differences of Monitoring Objects.

Abstract: Ginkgo landslide, located in Ginkgo village, Xixia County in Henan province, is a large earthiness landslide. Considering its serious deformation and the possible serious instability disaster of the landslide, GPS was chosen to monitor this landside. This paper systematically introduces the monitoring program design, data acquisition, data processing, data analysis when GPS was used in Ginkgo landslide monitoring. According to GPS monitoring result analysis, the landslide is at a stage of constant speed deformation. And the rainfall is the main factor inducing the landslide sliding. It’s suggested that close attention should be paid to the landslide when encounter rainstorm, heavy rain or a long time raining so that to relief and prevent disasters.

Abstract: Three-dimensional laser scanning technology, short for 3D laser scanning technology, is another innovation in surveying and mapping technology after GPS space positioning technology. This paper introduces the 3D laser scanning technology applied in the Ginkgo landslide monitoring. In this paper, the monitoring schematic design, data acquisition, data processing and data analysis are systematically introduced. It follows that Ginkgo landslide overall deformation characteristics, 3D laser scanning technologys strengths and weaknesses in the landslide monitoring. It is promising for the application of 3D laser scanning technology in landslide monitoring.

Abstract: Wireless Sensor network (WSN) is an emerging technology widely applied in environmental disasters monitoring. With the constraint of computation resource, it face big challenge of stability and reliability of monitoring network. A statistical model of strain data and distributed monitoring algorithm for landslide based on WSN is studied in this paper. The strain data is modeled using variable mean of Gaussian process. Miss alarm rate and false alarm rate are introduced as critical performance parameters of landslide prediction. Comparing with centralized monitoring method, simulation result shows that distributed monitoring algorithm performs better than centralized monitoring.

Abstract: This article describes the successful application of video surveillance technology in various fields of security, government, education, expounds some commonly used landslide monitoring methods and characteristics of remote video monitoring system, demonstrates that it’s essential to apply the remote video surveillance to landslide monitoring. That remote video surveillance technology and professional platform software are combined establish a set of landslide video surveillance system. Through the real-time pictures, we can make reasonable explanation for the phenomenon of abnormal fluctuations, thus the damage due to unexpected geological landslide can be prevented and timely resolved.

Abstract: Our country is one of the countries that with serious geological disasters,every year we loss nearly twenty billion yuan and hundreds of people dead because of it. Bazimen landslide is one of them.Based on the research of Engineering geological characteristics，formation mechanism，failure mode and later change trend of Zigui county Bazimen landslide in Three gorges reservoir area,we put forward the warning construction scheme of landslide monitoring, introduce the layout of monitoring network and the construction technical requirements of all kinds of deformation monitoring,it can be refered to by other landslide monitoring projects.

Abstract: Abstract: This article summaries the importance of the technology of landslide monitoring, also describes main methods of landslide monitoring and new means of analysis of landslide deformation, at the same time, it briefly describes the classification of detection technology of landslide deformation and points out the prospect of engineering application of landslide monitoring technology.
