Experimental and Theoretical Dynamic Compliances of Foundations
An experimental study of the dynamic behavior of surface foundations on granular soils by centrifuge modeling is presented. The test method allows a direct measurement of the complex-valued...
Mass and Energy Tradeoffs of Axial Penetration Devices on Lunar Soil Simulant
Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill...
Design of a Support and Foundation for a Large Lunar Optical Telescope
NASA is considering a large lunar telescope [LLT] and a smaller diameter precursor telescope experiment on the Moon. The preliminary design of the 16-meter optical aperture is being performed...
In Situ Recovery of Water from Dormant Comet Cores & CI Carbonaceous Chondrites
Water and volatiles may be produced by drill holes into dormant comet cores or class CI or CM asteroids. This is modeled after in-situ mining as in the Frasch process sulfur mines of the...
The Transport and Fate of Drilling Muds
The disposal of drilling muds from offshore oil platforms is of concern because of the potential effects of pollution from these muds. Both drilling muds and fine-grained bottom sediments...
Offshore Pile System Reliability
The existing design methodology for offshore pile foundations is evaluated relative to the ultimate performance of the foundation system using reliability techniques and data from three...
Stochastic Finite Element Analysis of a Damped Beam on Random Foundation and Subjected to Fast Moving Loads
The dynamic effect of fast moving loads on a rail is analysed by the perturbation-based stochastic finite element method. The rail is modeled as an elastic beam resting on the Winkler...
Probabilistic Evaluation of Bearing Capacity of Shallow Foundations
A probabilistic model is developed to evaluate the bearing capacity of shallow foundations. The bearing capacity formulation proposed by Terzaghi is used but with the bearing capacity...
Agricultural Drains and Safety of Dams
Bonny Dam is located in east central Colorado on the South Fork Republican River. The dam's foundation is in the relatively porous Ogallala formation. Throughout the history of the dam,...

New Cruise Terminal for San Francisco
A new international Cruise Terminal is being developed at Pier 30-32 in San Francisco, to replace present inadequate facilities at Pier 35. The Cruise Terminal will be developed as part...
Signing Systems: Directional, Identity, and Graphic Systems for the Port of Long Beach
The authors have developed (in conjunction with Port staff) a revolutionary roadside communication system for The Port of Long Beach. The system includes: Renamed piers for easier understanding...
Vacuum Alumina Unloader for Port of Everett
The Port of Everett is in the process of rebuilding and expanding its marine cargo facilities. Much of the Port's waterfront land and facilities were lost to the U.S. Navy Carrier Homeport...
Modifications to Coal Pier 6 Made Necessary by a Deeper Channel
In 1987 it became apparent to the Norfolk Southern Corporation that the U.S. Army Corps of Engineers proposed dredging of the Norfolk, Virginia Harbor would become a reality. Coal Pier...
Pile Installation and Testing at Ningbo Port, China
As part of an ambitious development program at the Port of Ningbo, the People's Republic of China constructed a 694 m (2277 ft) long offshore pier structure to provide a container berth...
Analysis of a Wharf for a Container Terminal
A balanced combination of sophisticated computer programs was employed to model the soil strata, foundation and structure of a wharf for a new container terminal in the Port of Topolobampo,...
Deep Water Container Wharf & Crane Foundation
A deep water anchored steel bulkhead and a parallel-independent low-profile, pile supported crane rail foundation with special stowage areas are discussed from soils investigation, through...
Pile Lateral Load Test in the Port of Los Angeles
Recent wharf projects in West Coast ports have featured rock dikes to contain backland fill and the use of vertical piles embedded in the rock dikes to resist lateral loads. This paper...
Proposed Seismic Design Method for Piers and Wharves
Current seismic provisions of the 1991 Uniform Building Code (UBC-91) and the 1983 AASHTO Seismic Design Specifications (AASHTO) are compared as they relate to piers and wharves. An alternate...
Seismic Rehabilitation of Seattle's Pier 69
The Port of Seattle, one of the largest on the west coast of North America, made a strong statement regarding their support for reusing existing structures when a decision was made to...
