Abstract

High slopes in water conservancy and hydropower projects are exposed to complex working conditions involving long-term multi-field coupling, with frequent time-dependent deformation and local instability. Traditional static and unified support models are difficult to adapt to the long-term performance evolution of slopes, and there are obvious shortcomings in engineering treatment adaptability. Taking stability management and control of hydraulic high slopes as the research focus, this paper systematically reviews the main control mechanisms of slope instability based on multiple types of stability analysis methods. Combined with different slope failure characteristics, a differentiated composite support system with multi-technology coordination is constructed. Meanwhile, according to the differences in working conditions throughout the whole life cycle of projects, a collaborative mechanism integrating staged dynamic management and intelligent early warning is established. The results show that the treatment model combining zoned support with whole-cycle dynamic regulation can effectively improve the homogenization defects of traditional support, enhance slope stability during the construction and operation and maintenance stages of hydraulic projects, and provide feasible technical reference for refined design and safety management in similar projects.
