Precision in Depth. Engineered for Resilience. Yanjian is a distinguished Senior Structural Engineer with over 30 years of specialized expertise in the design and lifecycle management of complex underground systems. From high-capacity metro stations to large-scale municipal tunnels and bridge foundations, Yanjian has dedicated his career to mastering the structural challenges of high-density urban and sub-aqueous environments.
As a former Chief Structural Engineer at SMEDI, one of China’s premier infrastructure firms, he has directed the technical delivery of critical subterranean works across more than 15 major cities.
At Avodahtec, he serves as a Structural Engineering SME, bridging the gap between sophisticated numerical modeling (SAP, ANSYS) and the practical execution of heavy civil, municipal, trenchless, and underground infrastructure projects.
A Global Authority in Subsurface Infrastructure. Yanjian’s portfolio is defined by high-stakes technical leadership, having directed the design and review of over 25 major metro and tunnel projects. His experience includes serving as the structural authority for the Shanghai Zhoujiazui Road Cross-River Tunnel, a massive 14.5m diameter shield tunnel, and the Wuhan East Lake Tunnel, the nation’s first to cross beneath its largest urban lake.
Beyond project execution, Yanjian is a contributor to the engineering profession’s regulatory framework, having co-authored the mandatory national standard for municipal works undercrossing high-speed railways (TB 10182-2017).
Mastery of Complex Site and Retaining Systems. With a deep academic background from Southwest Jiaotong University and over 30 peer-reviewed publications, Yanjian possesses a mastery of soil-structure interaction.
Whether he is leading comprehensive site investigations for 100+ km of TBM-driven tunnels, conducting structural condition assessments for aging transit hubs, or designing high-pressure water and earth retaining structures for deep excavations (up to 17.5m), Yanjian is dedicated to delivering resilient, code-compliant infrastructure that meets the highest standards of safety and operational excellence.
