Abstract: Compensation grouting has been widely applied for the vertical deformation control of constructed facilities. However, few studies have been conducted on the horizontal displacement control of underground facilities using ...

Abstract: Existing structures can deform and damage due to newly constructed underground structures, which induces surrounding soil deformation due to ground loss and stress relief. Compensation grouting is an active control method ...

Abstract: The capsule expansion technique (CET) is a novel active measure to control the deformation of subsurface structures induced by underground engineering construction. CET has been applied to tunnel deformation control, but ...

Abstract: Previous studies on compaction grouting focused more on clay but paid less attention to sand. In this paper, using the Nor-sand model, an finite difference method (FDM) simulation was carried out to study the grout efficiency ...

Abstract: Capsule expansion technology (CET) is innovatively developed to protect subsurface structures from underground engineering construction. However, it has hardly been reported in pile settlement control using CET. In this ...

Abstract: Controlling tunnel response induced by lateral excavation in soft clay has become a significant focus of modern research. Capsuled expansion is an innovative active control technique used to control the deformation of ...

Abstract: A grouting technique is introduced as a measure to protect tunnels adjacent to a large-scale excavation. Field measurements indicated that this grouting technique reduced the maximum horizontal displacement in the tunnel ...
