Maintenance
While site selection and proper construction are the most critical factors in establishing that permeable pavements function as designed, all must be inspected and maintained to maximize...

A Simple Model to Predict Soil Resistance to Driving for Long Piles in Deepwater Normally Consolidated Clays
As the exploration and development for offshore oil and gas reserves moves into the deepwater environment of the continental slope, a good model is necessary to evaluate drivability of...

Dynamic Shearing Properties Of Compacted Clay
A series of 116 Q-type triaxial compression tests was performed using specimens of Goose Lake clay compacted at water contents ranging from 9 percent dry of optimum to 3 percent on the...

Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...

Estimation of Consolidation Properties of Clay from Field Observations
Analyses to obtain theoretical time-settlement curves for embankments typically make use of soil properties measured in the laboratory on small disturbed samples subject to strain rates...

Radial Flow Consolidation Testing
A radial flow consolidation cell that can be used with commercially available loading frames was developed and a series of tests were performed on samples of sedimented kaolin. Simple...

Measurement of Hydraulic Conductivity of Partially Saturated Soils
Increased interest in protection of the environment has led to a need to be able to predict long-term movement of moisture, and contaminants, in the vicinity of shallow land disposal sites...

Axial Load Capacity of Pipe Piles in Sands
The axial load capacity of driven, open-ended, steel pipe piles in cohesionless soils, is often estimated using a method such as the American Petroleum Institute Recommended Practice 2A...

Behaviour of Open-Ended Pipe Piles in Sand During Installation and Loading
An experimental study was performed to investigate the physical processes which influence the axial load capacities of open-ended steel pipe piles in sand. A double-walled pipe pile was...

Performance of Suction Caissons in Sand and Clay
The use of suction caissons (suction piles) in marine environments has been increasing in the last decade. A suction caisson is a steel pipe with an open bottom and a closed top that is...

Shear and Interface Strength of Clay at Very Low Effective Stress
Thin-specimen direct shear (TSDS) tests were conducted to measure the shearing strength of kaolinite, and interface strengths between kaolinite and acrylic plastic and anodized aluminum,...

Effective Stress Theory of Soil Compaction
The shape of the moisture-density curve obtained from compaction tests has been explained in terms of capillarity and lubrication, viscous water, and physico-chemical interactions. None...

Finite Difference Analyses for Sand Drain Problems
The geotechnical literature contains a number of papers in which sand drain installations are described and field performance is compared with theoretical predictions. Some of the field...

Pore Water Pressures in Unsaturated Soils
Unsaturated soils are three-phase systems composed of solid mineral matter, water, and air. Such soils may be formed by either natural or artificial means. Except in moist environments,...

Pile-Driving Formulas for Friction Piles in Sand
Dynamic pile-driving formulas are widely used in predicting the load-carrying capacity of friction piles and in writing pile-driving specifications. Further, when load tests are available,...

Axial Capacity of Steel Pipe Piles in Clay
Development of theories for the prediction of the axial compressive and tensile load capacities of driven piles is made difficult by a variety of factors, e.g., disturbance of the soil...

Offshore Technology in Civil Engineering
Hall of Fame Papers from the Early Years
Prepared by the Program Committee of the Offshore Technology Conference of the Coasts, Oceans, Ports, and Rivers Institute of ASCE. This series presents...

Application of Model Pile Tests to Axial Pile Design
Experiments conducted with instrumented model pile segment probes at Harvey and Empire, Louisiana are summarized and the observed behavior interpreted. Correlations are developed for the...

Case Study of Offshore Pile System Reliability
This paper presents the results of research effort to evaluate the reliability of offshore pile foundation systems. It is an extension of previous work by the authors [14] dealing with...

Geo-Shanghai 2014
Proceedings of the Geo-Shanghai 2014 International Conference, held in Shanghai, China, May 26-28, 2014. Sponsored by the Geo-Institute of ASCE. These...
