Homogeneity Tests Based Upon Gumbel Distribution
This paper analyzes the performance of three homogeneity tests for Gumbel distributed flood flows. The classic Dalrymple test, a method-of-moment Cv test, and a normalized-quantile test...
A Technique to Perform Coupled Consolidation Analysis Using Two Independent Softwares
The consolidation of soils involves two interdependent processes. These are fluid (air and water) flows and the deformation of the soil structure. The two processes tend to be treated...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....

Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...
53 WAK Tests on Spread Footings
Research on the prediction of soil stiffnesses of spread footing-soil systems using Wave Activated Stiffness (K) or WAK tests was conducted. As discrete lumped-parameter model with a mass,...
Vertical and Horizontal Deformations for Foundations on Sand: An Experimental Study
A natural scale model is used in order to investigate experimentally the sand soil deformation behavior which accepts loads by shallow foundations. The vertical and horizontal soil displacements...
Uplift Load-Displacement Behavior of Grillage Foundations
Full-scale field tests were conducted on steel grillage foundations for lattice transmission line towers that had been in place since 1929, 1947, and 1958. A total of eight tests were...
Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...
Analysis of the Juturnaiba Embankment Dam Built on an Organic Soft Clay
The Juturnaiba Dam, located in the northern part of Rio de Janeiro State, Brazil, has 1.2 km of its length built on an organic soft clay about four meters deep. The construction of the...
