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...
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...
An Investigation of the Reinforcing Effect of Stone Columns in Soft Clay
A proposed major extension to an iron ore handling yard was located in an area underlain by soft alluvial clay. Stone columns were proposed to limit settlement of rails supporting the...
Prediction of Settlements of Footings on Sands: Accuracy and Reliability
Serviceability limit states are controlled by the deformations that a specific structure can undergo. This aspect involves a correct design of foundations to ensure that the supported...
Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...
Design of Underpinning Piles to Reduce Settlements
Piles are frequently used to underpin structures which have suffered, or are expected to suffer, damage due to excessive settlement or differential settlement. However, existing methods...
Comparison of Settlement Predictions for Single Piles in Sand Based on Penetration Test Results
The analysis of settlement for driven piles in cohesionless soils is a complex soil structure interaction problem. The total settlement for such a pile is generally considered to be the...
Settlement and Deformation Response of a Bridge Footing on a Sloped Fill
The problem of settlement of spread footings located within or near granular slopes has been investigated in the laboratory using a large testing facility. Based on these results, footings...
Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...
Nonlinear Three Dimensional Analysis of Downdrag on Pile Groups
The downdrag on pile groups was investigated by using a numerical analysis and an analytical study. The emphasis was on quantifying the reduction of downdrag on piles in a group due to...
Load-Settlement Prediction of Footings on Steep Slopes
The use of spread footings on slopes is a common practice in the design of bridge foundations. Footings are generally constructed in the slope or at its crest to minimize the bridge length,...
Numerical Modeling of Bridge Approach Settlement with Foundation-Embankment Interaction
Bridge approach settlement is one of the major problems facing the transportation agencies responsible for road construction and maintenance in the United States and in many other countries...
Probabilistic Observation Method for Settlement-Based Design of a Landfill Cover
Uncertainties in subsurface conditions make predicting total and differential settlement a difficult task. The Observation Method, which is commonly implemented to acquire additional knowledge...
Tolerable Deformations
Current criteria for tolerable movements of buildings, bridges and other structures are reviewed. Tolerable values of total and differential settlement, relative rotation, relative deflection...
Settlement Analysis for 450 Meter Tall KLCC Towers
The site evaluation and settlement analysis performed for the two tallest buildings in the world currently under construction, are described. The site evaluation resulted in shifting building...
Effect of Roughness and Thickness of Biofilms on External Mass Transfer Resistance
The effect of roughness and thickness of biofilms on the dissolved oxygen (DO) concentration boundary layer thickness (DO CBLT) and the external mass transfer process in a biofilm system...
Demonstration Project for Scour Instrumentation
A Federal Highway Administration (FHWA) Demonstration Project was developed to facilitate technology transfer of instrumentation related research to the highway industry. The objective...
Real-Time Data Collection of Scour at Bridges
The record flood on the Mississippi River during the summer of 1993 provided a rare opportunity to collect data on scour of the streambed at bridges and to test data collection equipment...
Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...
Hydrodynamic Forces in Hydraulic Jump Stilling Basins
The knowledge of hydrodynamic forces acting on hydraulic jump stilling basin slabs has been a research topic for the past four decades. Published methodologies for computing the hydrodynamic...
