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...
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...
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,...
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...
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 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...
Numerical Study of Underpinning by Piles for Settlement Control of Strip Foundations
A numerical study has been carried out of a simple idealized problem of a shallow strip foundation (both flexible and rigid) on clay underpinned by rows of piles. The work is directed...
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...
Reduction of Settlements Using Soil Reinforcement
This paper presents the experimental and finite element method (FEM) of analyses performed to model the use of soil reinforcement for rehabilitation of gantry crane track foundations....
Strip Foundation on Geogrid-Reinforced Clay
Laboratory model test results for the ultimate bearing capacity and allowable bearing capacity at various settlement levels conducted on a strip foundation supported by geogrid-reinforced...
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...
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...
