BEHAVIOUR OF GRAVITY CAISSON ON SANDBED
Gravity caissons are proposed as the wharf structure for the Port of Singapore Authority's (PSA) Third Container Terminal. Conveyance of cargo at this terminal will be undertaken by new pilotless automated guided vehicle (AGVs) operation which may be adversely affected by ground movement exceeding …

A numerical study of the suitability of rigid inclusion ground reinforcement beneath caisson quay walls
… for reinforcement of the foundation of a caisson quay wall functioning as a container terminal. Apart from their brittle behaviour under lateral loading, rigid inclusions are well suited to the large uniform loads and stringent post-construction deflection tolerances associated with …

Evaluating soil pressures on a deep foundation element due to liquefaction-induced lateral spreading
… The kinematic loadings on a large, rigid caisson due to an all-sand profile undergoing liquefaction and subsequent lateral spreading are evaluated in this thesis. While a relatively large volume of work has been completed pertaining to the lateral loads imposed on flexible foundation …

Implementation of Self-Consolidating Concrete for Bridge Applications
… SCC. SCC was incorporated for cast-in-place caissons as well as precast/prestressed beam components.;Prior to use of a 4,500 psi mix for the caisson applications, deemed SCC-1, a novel test procedure was developed to assess the uniformity of SCC within a model caisson member. Instead of …

Multichannel maximum entropy method of spectral analysis applied to offshore structures
… shape identification of a triple decked, single caisson offshore platform. The superiority of the multichannel Maximum Entropy Methods relative to conventional spectral analysis techniques in calculating these cross-spectral estimates and evaluating mode shapes is demonstrated.

Calcul des poutres-caissons par la méthode des assemblages des plaques
… développée pour l'analyse élastique des poutres-caissons sous l'effet des charges statiques. Dans cette méthode, des fonctions harmoniques qui satisfont les conditions aux limites (moments de flexion et forces de membranes) dans la direction longitudinale, sont utilisées conjointement avec des …

Application of numerical limit analyses for undrained stability problems in clay
… (short-term) pullout capacity of a single caisson cell in clay is initially investigated as a planar problem. Limit analyses show that the capacity can be presented as a normalized function of the undrained strength gradient in the clay, and interior surface area of the caisson. The results …

CONCEPTION ET DIMENSIONNEMENT D’UNE PONT SUBMERGÉ DANS LE LAC LÉMAN
… deux compartiments de ballast disposé dans le caisson qui permet soit de submergé les pièces que de régler les charges gravitaires pour qu’elles soient parfaitement en équilibre avec la poussée d’Archimède lors de la phase de service. Le tracé du pont se développe principalement le long de la …

Denial-of-Sleep Vulnerabilities and Defenses in Wireless Sensor Network MAC Protocols
… Anti Sleep-Deprivation for Sensor Networks, or Caisson, suite includes a lightweight, platform-independent anti-replay mechanism, an adaptive rate-limiter and a jamming detection and mitigation mechanism. These tools are designed to be applied selectively or in concert to defend against …

The cyclic behaviour of sand, from the Prevost model to offshore geotechnics
… consists in the modelling of a suction caisson, part of a tripod structure for wind turbines. An axisymmetric representation of this foundation is carried out. It is assumed embedded into dense Lund sand described by the Prevost model. Monotonic and cyclic simulations are performed in …

Experimental and numerical investigations to assess the behaviour of a buried pipeline in areas with high geological instability
… pipe during landslide/fault tests in which one caisson was moved up to 4 m respect to the initial position. These experimental findings confirm that sand with a low value of maximum achievable density may prevent from high loads developing on pipelines, in contrast to native soil which can apply …
