With the increasing focus of the construction industry on earthquake disaster prevention and mitigation, and the growing emphasis on the safety of construction projects, improving the disaster prevention and mitigation capabilities of construction projects in earthquakes has become a critical issue that needs immediate attention and is of great concern to all parties. Against this backdrop, on February 21, 2025, Dr. Qiu Rendong, leading an expert team from the Foundation and Substructure Institute of China Academy of Building Research (hereinafter referred to as "the Institute"), visited Beijing Vibrating Compaction Engineering Machinery Co., Ltd. (hereinafter referred to as "Beijing Vibrating Compaction Machinery"). The two parties conducted in-depth exchanges on the application of the vibration compaction method in earthquake disaster prevention and mitigation for geotechnical foundations, achieving significant results.
At the exchange meeting, Dr. Qiu Rendong, with his rich experience in rock and soil earthquake engineering research, first gave a clear overview of the core issues of concern in China's rock and soil earthquake engineering field. From seismic damage investigation, simulation experiments, and data monitoring, to cutting-edge theories and breakthroughs in innovative technologies, all of these can provide strong evidence and technical support for the application of the vibration compaction method in the field of rock and soil earthquake engineering. Dr. Qiu Rendong stressed that vibration compaction, as a mature ground improvement technology, has shown significant performance in improving the seismic disaster prevention and mitigation capacity of foundations, especially in enhancing the anti-liquefaction capability of soil. Its application potential in high-intensity earthquake areas has been widely recognized. Specifically, in areas with seismic fortification intensities of 8 and 9 degrees, vibratory compacted stone columns have shown significant advantages, and future efforts should focus on strengthening communication and cooperation with domestic earthquake organizations and associations.
Professor Zhu Chunming from the Institute also shared his unique insights on the application of the vibration compaction method in the field of earthquake engineering. He emphasized that in areas with frequently occurring earthquakes and soft soil foundations, the use of vibratory compacted stone column reinforcement technology can significantly improve the density and shear strength of the soil, thus significantly enhancing the strength and deformation resistance of the foundation under seismic conditions. He further explained that it is necessary to flexibly adjust the construction parameters of the vibration compaction method according to local seismic characteristics and geological conditions to ensure optimal treatment effects. For example, in strong earthquake areas, the length and diameter of the vibratory compacted stone columns can be appropriately increased to enhance their reinforcement effect; while in areas prone to sand liquefaction, it is necessary to finely control the water pressure and compaction time to improve the anti-liquefaction capacity of the soil.
Finally, Zhang Guangbiao, general manager of Beijing Vibrating Compaction Machinery, expressed his sincere gratitude to Dr. Qiu Rendong, Professor Zhu Chunming, and the other industry experts who participated in the visit. He stated that the professional insights and pragmatic ideas of the experts have clearly guided the company in expanding its business in the application of the vibration compaction method in earthquake disaster prevention and mitigation, and in deeply understanding the importance of earthquake disaster prevention and mitigation technology and public services. The company will fully utilize the achievements of this exchange, combine its own advantages in engineering machinery manufacturing and construction, actively explore innovative applications of the vibration compaction method in the field of ground treatment, and contribute more to the earthquake disaster prevention and mitigation cause and public safety in the construction industry.
This exchange activity has established a good platform for cooperation between Beijing Vibrating Compaction Engineering Machinery Co., Ltd. and others in the field of rock and soil earthquake engineering disaster prevention and mitigation. Looking to the future, the two sides will further deepen their cooperation in various dimensions, including technological research and development and project implementation, jointly promoting the wide application and technological innovation of the vibration compaction method in the field of ground treatment, effectively enhancing the disaster prevention and mitigation capabilities of construction projects, and better serving society.
