Teaching Soil Mechanics Laboratories with Computer Assistance
This paper discusses the methods involved in teaching the laboratory section of an undergraduate course in soil mechanics using computer assistance. The lab covered one semester with students...
Expert System for Bridge Scour and Stream Stability
Significant engineering judgment is required to ascertain the scour susceptibility of bridges. This judgment is typically acquired through many years of experience. This paper describes...
Bridge Condition Rating Using Fuzzy Sets and an Eigenvector of Priority Settings
A simplified methodology for combining the condition rating of the various elements of bridge components (deck, superstructure or substructure) is developed using a multi-attributive decision...
Contemporaneous Development of Field Data: Transportation Construction Claim Defense
This paper addresses the continuing development of a construction field database system documenting resources applied on the jobsite by Contractors. The paper focuses on the case study...
Effects of SPT Equipment and Procedures on the Design of Shallow Foundations on Sand
The effect on our computations of bearing capacity and settlement of shallow foundations suggests that as more efficient SPT hammers and procedures are used, our shallow foundation designs...
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,...
WAK and Full-Scale Load Tests on Granular Fill
For footings on granular fill that includes cobble- and boulder-size materials, in situ tests cannot be used to estimate foundation settlement because such fill is difficult to explore...
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....
Settlement of Shallow Foundations on Sand
A new method for estimating the settlement of shallow foundations on sand is presented. The method is based on elastic stress-strain theory and is designed for use with soil data from...
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...
Pile Settlement Based on Dynamic Measurements
Dynamic measurements during driving are well established for monitoring driving performance and the prediction of pile capacity. Post driving, signal matching office methods (e.g. CAPWAP)...
Testing and Predicting the Movement of a Drilled Shaft in New Mexico
The New Mexico State Highway and Transportation Department (NMSH&TD) have been using drilled shafts for supporting bridges in the State of New Mexico. Several drilled shafts were...
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...
Design and Performance of a Piled Raft Foundation
The foundation system for a recently constructed building in Perth, Western Australia, consisted of combined pile groups and raft elements, with a total of 280 bored piles incorporated...
Model Tests on Caissons
Laboratory tests were conducted on model caissons to better understand the settlement/deflection behavior of open ended caissons on sandy soil, with embedment depth, caisson diameter,...
Settlement Evaluation for Cap Closure Performance
Predicting short and long-term performance of a landfill cap system is a difficult task considering the generally unknown nature of the waste and magnitude and variation of settlement...
Preloading Organic Soils to Limit Future Settlements
This paper presents the authors' experience in preloading organic soils in south Florida to allow the construction of roadways, utilities, and low-rise residential structures on shallow...
The Control of Settlement Using Geogrids
The applicability of geogrids in reducing settlements has been investigated in the laboratory in two separate studies, in unpaved roads under cycled load applications, and as overlays...
Blast Densification of a Thick, Loose Debris Flow at Mt. St. Helen's., Washington
Numerous debris flows occurred during the 1980 eruption of Mt. St. Helen's in Washington State. The proposed location of Bridge 12 over Coldwater Creek along State Route 504 is underlain...
