Performance of a Steel Tank Founded on a Marine Clay
For tanks on soft clays, the soil is often preloaded before tank construction to increase bearing capacity and minimize post-construction settlement. In the case history described here,...
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...
Long Term Performance of Raft and Footing Foundations Above Clayey Silt
Two multistorey buildings have recently been constructed on a 30-m thick layer of clayey silt in downtown Fredericton, New Brunswick. The Bank of Montreal building is ten storeys high...
Influence of Flexible Mat on Settlements of Marine Clay
Highly compressible marine clays occur extensively in coastal regions. In lieu of traditional pile or raft foundations in such weak soils, recently a flexible mat system has been developed...
Vertical Displacement Induced in Soil by Conical Shell Foundations
Shells can hold prospect for adoption in foundation engineering only if they can be projected as economical alternatives to conventional flat foundations. Therefore, the initial enthusiasm...
Settlement of Structures Supported on Marginal or Inadequate Soils Stiffened With Short Aggregate Piers
A short aggregate pier system, which was developed to provide an economical alternative to the overexcavation/replacement technique, has been used since 1988 to control settlement of structures...
Displacement of Batter Piles in Layered Soil
The displacements of flexible vertical and batter model piles under eccentric and inclined loads in layered soil of clay overlying sand is studied. Horizontal and vertical displacements...
Down Drag on Friction Piles: A Case History
The down drag settlements experienced by the foundation of a supermarket constructed in 1972 in Gretna-New Orleans, Louisiana are presented. Two different lengths of piles (12.2 m and...
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...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
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...
Footing Modulus Near Slopes
A method is described for estimating the footing modulus of shallow spread foundations located near slopes of cohesionless material. The ratio of footing modulus for a shallow foundation...
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...
Modeling Settlements of an Existing Municipal Solid Waste Landfill Sideslope Using an Earthen Surcharge Pile
This paper discusses the results of a large-scale field compressibility test completed on municipal solid waste (MSW). The test consisted of surcharging the waste mass with an earthen...
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...
Building Performance Founded on an Improved Sand in Recife, Brazil
Studies performed on a fourteen-storey building founded on an improved sand are presented. These studies included soil profile characterization, the choice of foundation type, the ground...
Settlement of Footings on Granular Materials: Low and Large Strain Parameters
Many methods have been proposed to predict the settlement of shallow foundations on granular soils. The analysis of more than 200 case histories shows that there is no correlation between...
Measurements and Numerical Modelling of High Rise Building Foundations on Frankfurt Clay
Many high rise buildings were founded on Frankfurt clay on rafts applying average contact stresses in the order of 0.4 MPa. Beside rafts now piled-rafts are often used to reduce total...
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,...
