In this paper, a numerical investigation of the effects grout parameters on load response concrete pile-grout systems in soft clay is presented. The study examines influence diameter and depth bearing capacity pile under vertical lateral loads. research findings indicate that grouting can enhance single system by up to 27% loads 51% loads, depending used. This due grout's ability fill voids soi...

The embedment length (EL) of full-grouting rock bolts is a core factor in bolt reinforcement. Therefore, understanding the influence EL on reinforcement performance benefits quality. To realise this purpose, paper adopted numerical modelling method. In method, structural elements modified piles were used. elastic debonding law was incorporated into pile to model behaviour surface between and gr...

The load transfer mechanisms of cable bolts differ from those for normal rebar bolts. The cable bolts used in mines are basically steel strands with different constructions depending on the number of wires or elements and the way they are laid. Tendon bolts (rebar and cable) are normally evaluated for their strength and load transfer properties. The tendon strength can be evaluated by the tensi...

The 300 m-level high arch dams built in China have different degrees of valley-narrowing deformation the initial impoundment. This unexpected phenomenon may increase long-term safety risk dams. There are several explanations for phenomenon, and one explanations—that it is caused by a drop bedrock temperature—is still under debate. In this paper, coupled thermo-hydromechanical (THM) simulations ...
