Excavation compensation theory and supplementary technology system for large deformation disasters
Given the challenges in managing large deformation disasters in energy engineering, traffic tunnel engineering, and slope engineering, the excavation compensation theory has been proposed for large deformation disasters and the supplementary technology system is developed accordingly. This theory is based on the concept that “all destructive behaviors in tunnel engineering originate from excavation.” This paper summarizes the development of the excavation compensation theory in five aspects: the “theory,” “equipment,” “technology,” the design method with large deformation mechanics, and engineering applications. First, the calculation method for compensation force has been developed based on this theory, and a comprehensive large deformation disaster control theory system is formed. Second, a negative Poisson's ratio anchor cable with high preload, large deformation, and super energy absorption characteristics has been independently developed and applied to large deformation disaster control. An intelligent tunnel monitoring and early warning cloud platform system are established for remote monitoring and early warning system of Newton force in landslide geological hazards. Third, the double gradient advance grouting technology, the two‐dimensional blasting technology, and the integrated Newton force monitoring––early warning––control technology are developed for different engineering environments. Finally, some applications of this theory in China's energy, traffic tunnels, landslide, and other field projects have been analyzed, which successfully demonstrates the capability of this theory in large deformation disaster control.
The excavation compensation theory for large deformation disaster control is proposed.
The calculation method of the compensation force is proposed.
A series of large deformation disaster control systems are summarized.
The large deformation disaster control techniques for different engineering conditions are summarized.
The successful applications of the theory in energy, tunneling, and slope engineering are illustrated.
