Enter the type and serial number in your manual and always refer to this information when you need to contact your agency or. The type and the serial number of your product are indicated on the type plate. As a supplement to existing geotechnical instrumentation, the Global Positioning System (GPS) offers a reliable and efficient method for three-dimensional monitoring. Read carefully through the User Manual before you switch on the product. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, whilst surface monitoring by traditional surveying techniques is a relatively slow process which restricts the number of points that can be regularly monitored. Traditional surveying techniques and geotechnical instrumentation can effectively monitor one-or two-dimensional modes of motion. Since the area was generally inaccessible before and after the pre-loading process, special settlement measuring marks had to be designed and used together with a new criteria for the measurements and analysis of the settlement monitoring results.ĭam monitoring relies on the long-term measurement of small structural motions at regular intervals. The pre-load was proposed to improve the soil characteristics, which was classified as very soft clay. Today, the ESRF Alignment group uses the Leica TDA5000/5 motorized theodolite with automatic target recognition (ATR) for all high precision survey work. The terminal area was pre-loaded with about 6m height of sand, which was dredged from the inland approach channel containing a high percentage of water, which made it difficult to access the area.

In this particular investigation, a series of 2D. This is not the case in the current study where it was required to monitor the settlement of a container terminal (1200 m length x 500 m width) in the new Port Said East Port. measured on a Wild BC-2 analytical plotter used in comparator mode, with a standard deviation of 5pm. In the common practice, the object to be monitored is accessible and a precise leveling technique is adopted.
The common procedure is to fix an adequate number of settlement marks distributed properly over the ground or the structure and then observe the locations of these marks over a period of time.
Settlement monitoring is a traditional survey applications in which the movement of the ground or large structures is observed over a period of time in order to establish the magnitude and nature of movement with a view to assess the stability of the ground or the structure.
