Performance of Oil Storage Tanks on Vibroflotation Improved Hydraulic Fill in the Port of Tampa, Florida
The paper describes a case history of design, construction and performance monitoring of two 80,000 barrel oil storage tank foundations 35 meters in diameter on a soft hydraulic fill soil...
Geocell Mattress Effects on Embankment Settlements
Laboratory investigations and finite element analyses of geocell mattresses beneath embankments were performed to determine the effect of such mattresses in reducing settlements. Eight-foot...
Eccentric Settlements of a Rigid Foundation on a Consolidating Layer
The paper examines the eccentric settlement of a rigid foundation located at the surface of a poroelastic layer saturated with a compressible pore fluid. The base of the rigid foundation...
Influence of Spatially Random Soil Stiffness on Foundation Settlements
The effect of stochastic soil stiffness on the total settlement under the corner of a uniformly loaded flexible strip footing has been studied. The generated Young's modulus random fields...
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...
Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...
Deformation of Sand Foundations Induced by Earthquakes
This paper discusses the deformation of sand foundations during earthquakes based on the experimental results of centrifuge tests. A group of tests was conducted on two types of buildings...
Seismic Settlement of Shallow Footings on Sands
In this contribution, the progressive seismic settlement of shallow footings on cohesionless soils is calculated using a sliding block model. Beyond a critical horizontal acceleration,...
Soil-Structure Interaction During Mining Induced Ground Movements
Mining induced subsidence can result in significant ground deformation, which is generally non-uniform. Although this deformation occurs slowly with small inertial forces, it often results...
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...
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...
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...
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...
