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...
Quick Checks for Structural Computer Analysis
When working with general structural analysis programs, there are some fast ways to check the input and output. This paper reviews some methods for verification of results of computerized...
Facilitate Delay Claim Analysis with As-Built Schedule Databases
A computer-based As-Built Schedule Database can provide a useful tool for the investigation of project performance. The facts recorded in the database may be used to identify actual sequential...
Computer Use in Claims Analysis -- Roundtable Discussion
Preparation or defense of construction claims is inherently time consuming and often counter-productive. This outline discusses some tools currently used in the construction industry to...
CadVisor (CAD Equipment Analysis and Selection System)
This paper describes a system called CadVisor (CAD Equipment Analysis and Selection System) developed by the U.S. Army Corps of Engineers Construction Engineering Research Laboratories...
Use and Abuse of Settlement Analysis
Terzaghi's concept of settlement analysis included comparison of prediction with reality and investigation of the causes of the differences. Present usage is often limited to prediction....
Settlement of Embankments on Soft Clays
It is now possible to make reliable predictions of settlement of embankments on soft clays. In most situations, where the embankment is designed to resist undrained instability during...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
Settlement of Tanks on Clay
Steel tanks for storage of water, oil, and other liquids are capable of withstanding large, but not unlimited, settlements without damage. In most cases shallow foundations provide adequate...
Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...
Predicting Shallow Foundation Settlement in Sands from DMT
The dilatometer test is ideal for predicting the settlement of shallow foundations. It directly measures a modulus of the soil and has been correlated to predict stress history. Recently,...
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,...
Footing Load Tests on Sand
Four full size footings were load tested at a site in Texas. The embedded footings were situated on a thin layer of stiff clay underlain by a thick deposit of medium dense to dense sand....
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...
Settlement Behavior of an Avalanche Protection Gallery Founded on Loose Sandy Silt
An avalanche protection gallery located in the Swiss Alps was founded on alluvial ground close to the steep rocky mountainside. The rear retaining wall, at a variable distance of a few...
Displacement of Landmark Building Resulting from Adjacent Construction Activities
This paper describes the observations and presents comments related to the measurement of settlement and the avoidance of damage to a historic structure in the City of New York from adjacent...
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...
Horizontal and Vertical Movements of Bridge Piers Subjected to Ship Impact
Results of a detailed analysis to evaluate the potential horizontal and vertical movements of the piers of George P. Coleman Bridge, Virginia, in the event of ship impact are presented...
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...
Static Pile Load-Movement From Dynamic Measurements
Static loading tests have traditionally been performed to determine the characteristics of pile load-movement relationships. Due to the expense involved and time required, this type of...
