Abstract

Dam monitoring relies on the long-term measurement of small structural changes at regular intervals. Traditional surveying techniques and geotechnical instrumentation can effectively monitor one- or two-dimensional modes of motion. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, while surface monitoring by traditional surveying techniques is a relatively slow process which restricts the number of points that can be regularly monitored. As a supplement to existing geotechnical instrumentation, the Global Positioning System (GPS) offers a reliable and efficient method for three-dimensional monitoring. To date, GPS technology has been successfully applied to a variety of deformation monitoring applications. This is due to its ease of use, and capability of very high accuracy when the appropriate hardware, software and field procedures are implemented. This paper reviews current GPS technology in t...

大坝地表监测全球定位系统的现状
大坝监测依赖于定期对微小结构变化的长期测量。传统的测量技术和岩土工程仪器可以有效地监测一维或二维运动模式。然而,岩土工程仪器的空间分布通常局限于大坝建设过程中可以安装仪器的位置,而传统测量技术的地面监测是一个相对缓慢的过程,限制了可以定期监测的点的数量。全球定位系统(GPS)作为现有岩土工程仪器的补充,为三维监测提供了一种可靠、高效的方法。迄今为止,GPS技术已成功应用于各种变形监测应用。这是由于它易于使用,并且在实施适当的硬件,软件和现场程序时具有非常高的精度。本文综述了当前GPS技术的发展现状。

期刊介绍: The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
