    Dam Deformation Survey

    Uploaded by

    nz kumpulan
    The document describes a deformation survey of the Klang Gate Dam in Malaysia using terrestrial laser scanning. The laser scanning method collects a point cloud of the entire dam structure to accurately monitor movement. It compares the laser scanning results to total station measurements. The methodology involves scanning the dam surface with the laser scanner and capturing target points with the total station. Data processing involves registration and filtering of the point clouds followed by analysis of deformation rates and accuracy between the two instruments.

    DAM DEFORMATION SURVEY

    BY LASER SCANNING METHOD


    INTRODUCTION
    Dam Deformation Survey are used to monitor the
    movement of the structure very accurately to ensure the
    structure in healthy condition.
    The Geodetic Laser Scanner (GLS-2000) are capable
    of working in most real world environments under a
    variety of conditions.
    GLS-2000 will collect vast point cloud over the entire
    structure and will be examined.
    PROS AND CONS OF LASER SCANNER
    PROS CONS

    Accuracy. Expensive machinery.


    Cost effective. Require specialists to operate.
    Less manpower Some devices or components
    involved. may require a large space.
    Saves time. Reflection may hider scanning
    Easier error correction by lase scanner.
    and detection. Components require
    maintenance.

    WHY DAM NEED DEFORMATION MONITORING SURVEY?

     Deformation monitoring survey are very important


    in order to prevent disaster caused by deformation.
    The structure of a dam need continuous monitoring
    in order to see if unexpected changes have occurred.
     The cause of unexpected changes is by the water
    load at different water level, the weight of the dam
    and the underground movement in the area of dam.
    AIM

    TO PERFORM THE DEFORMATION MONITORING OF


    WATER DAM USING TLS METHOD
    TO EVALUATE AND ANALYSES THE ACCURACY OF
