Seven-wire strands are commonly used in civil-engineering structures such a cable-stayed bridges, pre-stressed concrete bridges or retaining walls structures. These civil engineering structures suffer from ageing and degradation due to corrosion and fatigue of structural steel members. Guided ultrasonic waves are potentially attractive tools for non destructive assessment of their integrity. Th...

Abstract Fully grouted rock bolting is commonly used in roadway reinforcement mining and tunnelling reinforcement.

Grouted Semi-flexible Pavement (GSP) is a novel pavement composed of open-graded asphalt concrete grouted with high-fluidity cement mortar. Due to its excellent load-bearing and anti-rutting performance, it has great potential as overlay surface in road construction. However, the understanding GSP performance remains limited pertinent findings are inconsistent. This article aims provide systema...

Slope reinforcement and the use of structural pile elements can be an effective slope remediation alternative when conventional remediation practices (e.g., improved drainage) fail to consider the causal factors leading to slope instability (e.g., strength loss due to weathering). An experimental research program was aimed at developing a rapid, cost-effective, and simple remediation system tha...

Rehabilitation of a watermain by grouted sliplining is usually carried out when the existing pipe is only partially deteriorated. Although designs that neglect the structural contributions from the existing pipe and the grout are generally conservative, the performance of the rehabilitated pipe needs to be better understood for effective design and management of buried water pipes. Presented in...

cet article est consacréà l’étude du dialogue dans enfance, récit autobiographique de nathalie sarraute qui contient des souvenirs de ses onze premières années. l’une des originalités de ce récit, se base sur la présence de deux voix narratives qui dialoguent tout au long du récit. l’une de ces dernières, joue le rôle d’une narratrice et l’autre représente le côté conscient de l’auteur qui suiv...

In order to study the damage mechanism of fissure-grouted rocks in abandoned mine pumped storage, uniaxial compression tests were conducted using rock specimens after dry and wet cycles. Additionally, acoustic emission sensors used track specimens. The results demonstrate a negative correlation between peak strength elastic modulus linear decrease wave velocity mechanical characteristics fractu...
