Bangkok: Using building structure measurement tools and equipment to survey the area around Wongwian Yai intersection yielded good results.
According to Thai News Agency, the Structural Engineers Association of the Thailand Research Fund (TRF) participated in a survey of Wongwian Yai roundabout. Following a successful survey of the area by a team from the National Science and Technology Development Agency (NSTDA) and researchers from the TRF, using structural measurement equipment, the association hopes to expand this initiative to continuously develop a monitoring system to address potential disasters.
Professor Dr. Sompong Khlaynongsuwan, Director of the Office of National Science, Research and Innovation Policy (NRCT), along with Professor Dr. Amorn Pimanamas, President of the Structural Engineers Association of Thailand, and a research team under the NRCT Fund, visited the Wongwian Yai area to develop and upgrade the use of building structure measurement tools and equipment, with the aim of expanding their application in solving disaster problems.
The Thailand Science Research and Innovation (TSRI) and its researchers have utilized technology and innovation to survey affected areas, ensuring national safety. They are also providing support by enabling researchers to develop a system for monitoring and measuring building structures to establish construction standards and continuous surveillance. In the future, they hope to expand the system to include monitoring water leaks, water levels, and turbidity, as well as real-time monitoring of tunnels, buildings, and soil subsidence, particularly at high-risk connection points, to further enhance public confidence, in coordination with relevant agencies.
Professor Dr. Amorn stated that the situation is now under control. Less water is flowing into the tunnel due to the use of chemical injections to harden the soil. The cracks are not expanding further, and no additional building tilting has been observed. However, continued monitoring is necessary to ensure safety, as the public has been alarmed by the ongoing subsidence. Furthermore, a real-time monitoring system for soil subsidence and building tilting has been implemented. This system utilizes numerous high-precision sensors to measure and track the tilting of structures affected by soil subsidence. Tilting is measured every second, and data from all sensors is sent to a central processing unit for collection, analysis, and display of the impact on buildings via the internet. Immediate alerts are sent to an application when the structure is at risk of damage exceeding predetermined criteria. Stakeholders can access this information through a dedicated website for reporting, enabling them to make informed d ecisions and take appropriate action.
Furthermore, photogrammetry technology, combined with AI and 3D laser scanning, is used for surveying and creating simulated maps from photographs. This allows for quick and accurate identification of damaged areas and building tilting, providing a more systematic spatial overview.
