Wednesday, 11 September 2024 // 7.00 - 8.30 pm
ABSTRACT:
Industry 5.0 is driving the integration of humans with robots, IoT devices, and AI for industrial automation. Fibre optics instrumentation plays a crucial role in this transformation, enabling automatic dynamic remote monitoring with high sensing resolution. It is also cost-effective for long-term monitoring and resistant to electromagnetic interference (EMI), moisture, and lightning. Fibre Bragg Grating (FBG) sensors and optical interrogators, integrated with cloud-based software monitoring systems, are already widely used for structural monitoring of pipelines, tunnels, buildings, railways, dams, as well as construction ground settlement and slope monitoring. This presentation will introduce various FBG technologies for these applications, aimed at enhancing cost-effective operation and maintenance in the construction and structural monitoring industries.

Wednesday, 26 February 2025 // 7.00 - 8.30 pm
ABSTRACT:
Bukit Timah Granite is a significant geological formation in Singapore, presenting unique challenges for Earth Retaining or Stabilizing Structures (ERSS) due to its weathering profile, jointed nature, and in-situ stress conditions. This presentation provides an in-depth analysis of the geotechnical design parameters required for ERSS in the Bukit Timah Granite. Key design considerations are addressed, including the use of the Generalized Hoek-Brown criterion and Mohr-Coulomb parameters to model rock mass behaviour. The presentation also highlights the implications of jointed rock models, and anisotropic material behaviour in the geotechnical design process. By synthesizing findings from multiple studies and field data, this work aims to optimize the safe and efficient design of ERSS in tropical weathered rock formations like the Bukit Timah Granite.

Tunnel Look Ahead Development for Singapore MRT Tunnelling Works
by Mr. Tan Yun Zhou, Cambridge Sensing Pte Ltd
Thursday, 17 April 2025 // 7.00 - 8.30 pm
ABSTRACT:
Tunnel Boring Machines (TBMs) face challenges in urban environments due to complex geology and congested underground spaces. This webinar introduces a high-resolution seismic look-ahead method that addresses these challenges without requiring cutterhead access or through-lining drilling. Using finite-difference wavefield simulations, the study demonstrates how seismic waves can travel ahead of the TBM and reflect from anomalies, where they are recorded by geophone arrays. The method was validated with seismic data from three Singapore MRT construction sites - C882, C885, and T316 - showing its reliability when compared to borehole logging data and TBM excavation parameters. This tunnel look-ahead system offers significant advancements in enhancing tunnel safety and efficiency, particularly in complex urban environments.
