Prediction of Ground Deformations Due to Excavation-Application to Tunnel Lining Design in Weak Rock
Prediction of ground deformations due to excavations is simulated by three dimensional non-linear finite element analyses. It considers various in-situ ground stress levels, excavation...
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,...
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...
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...
Analysis of the Juturnaiba Embankment Dam Built on an Organic Soft Clay
The Juturnaiba Dam, located in the northern part of Rio de Janeiro State, Brazil, has 1.2 km of its length built on an organic soft clay about four meters deep. The construction of the...
Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...
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...
Settlement Predictions at a Florida Port Facility
A paved container storage area approximately four acres in size has been constructed at the existing Port of Fernandina in Fernandina Beach, Florida. Approximately one-half of the site...
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...
Design and Installation of a New Settlement-Inclinometer Device
A new miniature settlement-inclinometer device (SID) system has been designed and built at the University of British Columbia for use in monitoring soft soil movements. The great advantages...
Settlement of Deep Compacted Fills in California
Measured settlement of deep compacted engineered fills from a single site were summarized and compared to data from other sites. The data indicate that the rate and magnitude of movement...
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...
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...
Stress-Deformation Behavior of an Embankment on Boston Blue Clay
An 11 m high I-95 embankment was thoroughly instrumented with piezometers, settlement rods and inclinometers to measure the behavior of the underlying 40 m thick deposit of Boston Blue...
Velocity Measurements by the One-Orange Method
Application of the most sophisticated instrumentation - so called state-of-the-art equipment - is not always necessary nor even desirable for measurement of mean velocities in verticals,...
