Abstract


The slope monitoring work is undertaken in order to ensure to grasp the condition of slope stability, reduce the landslides may be triggered by a series of serious geological disasters, high-speed smooth development has important practical significance for the protection of the people's life and property security and the national economy . Many at home and abroad for slope safety monitoring technology and methods, from traditional total station, inclinometer tube pressure gauge, rain gauges and displacement meter, to the new GPS, TDR, laser rangefinder, are a large number of applied to the actual slope monitoring. Comprehensive application of the method of monitoring technologies, the basic characteristics of the safety monitoring of slope. Traditional monitoring methods, although lacking in automation, digitization, but due to its use of a longer time, accumulated a lot of experience in engineering and technical means, and thus better stability. In comparison, the new monitoring instruments and techniques, the more advantages in timeliness. The sentinel surveillance technology exploring low-cost high-precision long-term the slope monitoring project in urgent need to address the problem. This paper focuses on this goal, the work carried out in the following aspects: 1, on the principle of laser range finder and constitute the analysis and combination of laboratory experiments to study its measurement accuracy and error level. On this basis, Zhuyong Highway K101 slope engineering practice, to build a laser ranging system and apply it to the scene monitoring, compared with the total station monitoring results analysis, affirmed its monitoring effect and application prospects. Principles and performance characteristics of the CCD (Charge Coupled Device, a charge-coupled device) micro deformation monitoring technology analysis, to explore the possibility for slope monitoring. At the same time, on the basis of the laboratory test, analysis of the main factors that affect the monitoring effect. Zhu Yong-speed Fukasawa landslide engineering background, and to build CCD micro deformation monitoring system will be derived from monitoring data Total Station, GPS, indicating their suitability for long-distance real-time monitoring of the slope engineering. 3, combining the advantages of remote data collection site and wireless network, designed and developed based on the wireless network Slope remote real-time monitoring data transmission system, laser rangefinder and CCD monitor different node design and hardware configuration. System for remote monitoring data transmission and AT send control commands instant, for the realization of two-way wireless network-based dynamic interaction provides a viable technology platform. Remote control software, a collection of laser ranging system and CCD micro deformation monitoring system developed to provide good conditions for the development of wireless monitoring technology.
