Beijing–Shenyang Railway Blasting Impact Monitoring
Project name: Beijing–Shenyang High-Speed Line Construction – Blasting Impact on Surrounding Environment
Brief introduction: Large-scale infrastructure projects, such as the construction of the Beijing–Shenyang high-speed railway, often encounter a variety of unique engineering challenges that require specialized solutions. One of the most significant challenges involves dealing with complex and varied terrain, where controlled blasting techniques become essential to effectively clear natural obstacles and prepare the ground adequately for the precise installation of railway tracks. However, conducting blasting operations in close proximity to cultural heritage sites, residential neighborhoods, or other sensitive structures introduces considerable risks. These risks demand careful and continuous monitoring, as well as meticulous management, to ensure safety and minimize potential damage.
To address this challenge, Dynatronic provided advanced monitoring technology to evaluate the environmental impact of blasting activities along the railway’s construction corridor. Engineers used the DE-884U network dynamic signal test and analysis system, combined with DH610 magnetoelectric speed sensors, to track and analyze vibration conditions in areas where blasting could potentially affect ancient architecture protection zones and surrounding buildings.
During blasting operations, the system continuously monitored vibrations in real time, capturing data on the intensity, frequency, and distribution of seismic effects. This information was processed using advanced analysis methods, including sound pressure cloud map visualization, which allowed experts to clearly see how vibrations spread across different locations and assess the potential risk to structures.
The monitoring results provided essential and detailed data support for experts responsible for evaluating the overall safety of the site. By carefully comparing measured vibration levels with established safety thresholds, project managers were able to ensure that blasting activities did not cause any harm or compromise the integrity of important cultural relics, nearby residential homes, or other critical infrastructure elements. Simultaneously, the availability of this data allowed construction progress to continue smoothly and efficiently, preventing unnecessary delays and minimizing downtime.
The project highlighted the importance of integrating real-time vibration monitoring systems into modern railway construction. By safeguarding the surrounding environment while ensuring construction efficiency, Dynatronic’s technology played a vital role in balancing infrastructure development with heritage protection and community safety.
