Description
<p> When subject to excessive loads in the context of excavation construction, earth retaining walls can undergo deformation that is challenging to assess visually, potentially resulting in accidents involving wall collapses. Hence, previous research has explored installing sensors within the retaining walls and using surface targets in conjunction with TS to measure deformation quantitatively. Nevertheless, these methods have presented significant challenges, including high costs, extensive labor requirements, and limitations in comprehensively assessing deformation. Therefore, we focused on cost-effective LiDAR technology, which offers the capability to provide real-time, comprehensive 3D data for measurement targets. We proposed a method for detecting deformations in earth retaining walls using LiDAR, representing a non-repetitive measurement approach. The experimental results demonstrated the effectiveness of the proposed method in detecting surface deformations in earth retaining walls. In the future, our objectives encompass applying this method to practice construction sites, identifying and resolving implementation challenges, and refining the proposed technique.</p>
