Analysis of construction response for mechanized construction of metro connecting passages

To investigate the influence of mechanized pipe jacking construction for connecting passages in weathered granite strata on the settlement and deformation of left and right shield sections of metro tunnels and ground surface, this paper takes the pipe jacking project of No.1 conn...

Generalized optimization method for fire evacuation routes in historic dense settlements based on improved ant colony algorithm and BIM

This study combines Building Information Modeling (BIM) with an improved ant colony optimization (IACO) algorithm to optimize evacuation paths during fires in historic dense settlements. A 3D village model was created using Revit, and fire simulations provided data on temperature...

An improved MADDPG-based framework for bidirectional safety management of construction robot interaction

Purpose Safety risks are particularly pronounced when multiple construction robots collaborate in complex construction environments. To enhance collaborative efficiency while ensuring operational safety, this study develops and evaluates, in a scaled simulation, a bidirectional s...

Experimental study on smoke propagation characteristics in dead-end tunnel networks during construction stage based on a small-scale model

Abstract This study investigates smoke propagation in Dead-end tunnel networks during the construction phase using a 1:30 small-scale physical model based on the Tianshan Victory Tunnel. The model consists of two main tunnels, a central service tunnel, and two cross passages, wit...
