This research demonstrates the effectiveness of 3D laser scanning techniques in measuring deformations in geotechnical applications, suggesting improved monitoring alternatives.
Key Points
The central aim is to assess the viability of using 3D laser scanning and photogrammetry in geotechnical laboratory tests.
Employed terrestrial laser scanning and digital close-range photogrammetry techniques.
Conducted monitoring of secant pile walls and soil movements.
Performed axial compression tests on secant pile walls.
The discrepancy between traditional methods and laser scanning was less than 3.0%.
The difference between traditional methods and photogrammetry was under 1.8%.
Both methods effectively tracked initial deformations and geometric irregularities.
