Dilatometer Tests for the Design of Grouted Piles in Rock
A case study of drilled and grouted piles in rock, which were analyzed using results of down-hole dilatometer tests is presented. The tests were performed from a jack-up platform in water...
In Situ Tests Aid Design of a Cylinder Pile Wall
In situ testing was used to verify geotechnical design parameters and modify construction for a 22 million dollar slope stabilization project near a major highway interchange. The project...
Pore Pressure Effects in Borehole Shear Testing
The effects of excess pore pressures on shear strength results obtained using the Borehole Shear Test (BST) were investigated. Pore pressures were measured during the consolidation, shear,...
The DMT - ?hc Method for Piles Driven in Clay
This paper presents a tentative method for evaluating the limiting skin friction f//s for piles driven in clay based on sigma //h'c (horizontal effective stress at the interface...
Site Characterization Using the Cone Penetrometer Test
The Cone Penetrometer Test (CPT) when used in conjunction with a limited soil boring program can provide a more detailed and economical site characterization. This paper addresses how...
Design Parameters for Grouted Piles in Rock From In-Situ Load Tests
A series of pile load tests were performed at an onshore site to develop final geotechnical parameters for the Gaviota platform foundation which consists of large diameter drilled and...
Skin Friction Evaluated From Friction Meter Test
This paper first describes the features of a specially developed friction meter and its operation method, and then reports in-situ test results conducted on various types of soils at two...
Uplist Capacity of Pile Foundations Using CPT Data
Southern California Edison Company has performed field uplift load tests on concrete driven piles, cast-in-place straight shaft piles and cast-in-place belled piers along transmission...
A Relationship Between Deformation Modulus and SPT N for Gravels
The results of over 200 horizontal plate load tests performed in situ in large diameter boreholes on gravels at various relative densities are used to develop a relationship between deformation...
N-Values Used to Predict Settlements of Piles in Egypt
A method is proposed for using the standard penetration N-values to predict the load-settlement curves for different piles used in Egyptian soils. The method is based on H. G. Poulos-E....
The Pressuremeter for Foundations: French Experience
The paper presents historical information on the development of the pressuremeter and its application in the Laboratories Central des Ponts el Chaussees (LCPC). The continuous research...
Aerated Static Pile Composting of Wastewater Sludge: A Field Study in Longmont, Colorado
This is a report of experimental work at the Longmont wastewater plant at Colorado, on aerated static pile composting of wastewater sludge. 61% of the sludge mass used in compost piles...
Nondestructive Evaluation of Timber Bridge Piles
A nondestructive technique for the determination of the in-place strength of timber bridge piling is presented herein. The testing technique is the ultrasonic wave propagation method in...
Harmonic Vertical Pile Response in Non-Homogeneous Medium
This paper describes the application of the boundary element method to determine the steady state response of vertically loaded floating piles in a non-homogeneous medium in which the...
Evaluation and Upgrading of Wood Structures
Case Studies
The need to evaluate and upgrade existing wood structures stems from concerns of safety and serviceability. These concerns are caused for a variety of reasons which include plans for continued...
Building on Water
During the last century, innovations in concrete have paved the way for the evolution of marine concrete structures. Oakland's proposed Carnation Container Terminal is using...
Wharf Stands on Stone Columns
A wharf was constructed in New Orleans on very weak soils. To prevent lateral and vertical movement of the soil, normally the entire wharf and adjacent structure would be founded on steel...
Influence of Artificial Island Side-Slopes on Ice Ride-Up and Pile-Up
An artificial island slope protection scheme must be able to inhibit ice ride-up and pile-up in order to minimize operational interruptions. The prediction of ice ride-up and pile-up mechanisms...
Centrifugal Modeling of Ice Forces on Single Piles
The ice forces and ice floe failure mechanisms associated with an ice sheet surrounding a vertical cylindrical pile were evaluated. A test system was developed to model ice forces in gravity...
Structural Solutions for the Enhancement of Gravity Foundations on Very Soft Arctic Soils
Very soft soils in several offshore Arctic areas cause a major concern in the design of gravity foundations, particularly in view of the high magnitudes of ice loads. Preliminary studies...
