AI Technical Summary
Existing technologies are insufficient for economically, safely, and reliably supporting high fill slopes with deep slippage. Traditional retaining structures are costly and their stability is difficult to control. A single retaining method cannot simultaneously meet the needs of both the upper fill and the lower deep slippage.
A flexible connection combined support device is adopted, including a retaining wall, a mattress layer and anti-slide piles. The anti-slide piles extend into the mattress layer and are fitted with elastic devices. The elastic devices coordinate deformation, and the opening and closing of the foaming agent and water bag are controlled by the tilting reaction device to prevent damage to the mattress layer and excessive compression of the elastic devices.
It achieves the coordination of displacement difference between anti-slide piles and retaining walls during deep slippage, prevents slope instability, economically meets the support requirements, protects the cushion layer from damage, and reduces project costs.
