TLDR
In this paper, the authors describe the procedure and results of a series of geotec-based geotechnical simulations of large diameter pipes and heavy vehicles, as well as their effects on pipe design.Abstract:
Large-diameter pipes, as well as heavy vehicles, have become increasingly prevalent, which imposes uncertainties on pipe design. This paper describes the procedure and results of a series of geotec...read more

Three-dimensional centrifuge and numerical modeling of the interaction between perpendicularly crossing tunnels
TL;DR: In this paper, the effects of induced stress on an adjacent tunnel were investigated and the authors concluded that tunnel driving inevitably induces changes in stress and deformation in the ground, which could cause ultimate and serviceability problems to the adjacent tunnel.
Journal ArticleDOI
A comparative study of the response of buried pipes under static and moving loads
TL;DR: In this article, a robust finite element analysis was used to investigate the effect of the truck speed, pipe stiffness and loading conditions on the maximum displacement of buried pipes, and it was found that the ratio of the static to dynamic pipe displacement decreases as the pipe stiffness increases and increases to a lesser extent as the vehicle speed increases.

Ming Xu,Dawei Shen,Boris Rakitin +2 more
TL;DR: In this paper, the longitudinal response of a reinforced concrete pipeline with gasketed bell-and-spigot joints subjected to traffic loading is investigated through three-dimensional numerical simulation.
Journal ArticleDOI
Experimental and numerical study on polymer grouting pretreatment technology in void and corroded concrete pipes
TL;DR: In this paper, an innovative trenchless pretreatment technology for concrete pipes with corrosion and void defects, termed as the membrane bag pile polymer grouting pretreatment (MBP-PGP) technology, was developed in the field test.
Journal ArticleDOI
The response of buried pipes to UK standard traffic loading
TL;DR: In this paper, the effect of pipe diameter and backfill height for rigid (concrete) and flexible (polyvinyl chloride (PVC)) pipes was studied using three-dimensional finite-element modelling.
