This paper analyses the engineering geological properties of the rocks and soils of the Canary Islands based on data from field studies, laboratory tests and extensive databases for volcanic materials. Geological properties and processes most relevant to geo-engineering are described. Geomechanical characterization of rock masses and soil deposits inclu...

This work analyses the influence of footing size and soil matric suction on the behavior of shallow foundations on unsaturated sandy soil, in terms of bearing capacity and settlements. Fourteen plate load tests were performed at the Experimental Site of USP/São Carlos. Rigid metal plates were used, with diameters varying between 0.20 m and 0....

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...

Dynamic 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...
