The Boston Central Artery/Tunnel (CAT) project consists of some 200 lane-kilometers of bridges, tunnels, and surface roadways. The central part of the project involves constructing two directions of multi-lane roadway to depths exceeding 30 m beneath the existing city by means of the slurry wall technique. The resulting walls, called Soldier Pile Tremmi...
View ArticleDynamic load test is often used for bearing capacity evaluation of driven pile foundation. It is also reported the successful use of this test in bored piles and caissons. This research is mainly concerned with the adaptation, performance and interpretation of the dynamic load test in circular steel plate aiming at the verification of the bearing capaci...
View ArticleThis paper describes a numerical investigation into the deflection of the upstream membrane of rockfill dams during reservoir impounding. The influence of the angle of the upstream slope on the subsequent deflection suffered by the concrete face slab is investigated. The procedure used for this investigation takes into consideration the gradual change b...
View ArticleAn expedite method to predict the shear strength of unsaturated soils is proposed and tested against many soils of different origins and subjected to different test types. The method uses an empirical hyperbolic function that has been successfully used to fit experimental data. The parameters of this function are obtained considering effective shear str...
