Seismic Cone Penetration Test
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...

Comparison of the SPT,CPT, SV and Electrical Methods of Evaluating Earthquake Induced Liquefaction Susceptibility in Ying Kou City During the Haicheng Earthquake
The capability of SPT, CPT, Shear Wave Velocity and Electrical methods to evaluate earthquake induced liquefaction susceptibility of soil deposits consisting of sensitive clayey silts...

Measurement of Vertical Ground Vibrations
This paper examines the use of surface and embedded mountings, to which transducers are attached for the measurement of free field vertical ground vibrations. Upper limits to the frequency...

Analysis of Liquefaction Potential by Insitu Testing
This paper describes the results of insitu testing performed to assess the liquefaction potential of a sand formation at a site for a proposed large industrial facility in East Central...

In Situ P and S Wave Velocity Measurement
A review of the in situ techniques to measure P and S wave velocities by seismic wave propagation is presented. A relatively new technique, the suspension PS logging method, is described...

North American Standard Penetration Test Practice: An Essay
The Standard Penetration Test (SPT) is the in situ mechanical soil test most used by North American geotechnical practitioners. The equipment and procedures of the test have periodically...

Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Coastal Protection Guidelines, Orange County, GA
As a result of coastal storms in the past several years the County of Orange (California) incurred large and unanticipated costs in providing emergency protection for private shorefront...

Wave Height Distribution in the Coupled Harbor
Wave height in a harbor sheltered by a breakwater is studied by numerical simulation and experiment. The coupled harbor, attained by setting up double arm breakwaters, was adopted as the...

Feasibility Study of Flood Control for the Maumee River in Allen County, Indiana
In March, 1982 the Maumee River overtopped its banks flooding parts of the City of Fort Wayne and unincorporated areas in Allen County, Indiana. The estimated damage to the area was about...

Laboratory Model Studies of Flood Wave Propagation
Laboratory investigations of unsteady free-surface flow with various combinations of channel and flood conditions were performed. A 72 ft (21. 9 m) long tilting flume was modified to make...

Solving Nonlinear Equations on a Hypercube
Certain classes of nonlinear systems of equations, such as polynomial systems have properties that make them particularly amenable to solution on distributed computing systems. Some algorithms,...

Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...

Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...

Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...

Seismic Interaction Among Numerous Masses Founded on a Viscoelastic Stratum
The steady-state harmonic response of systems comprising numerous masses resting on a homogeneous, viscoelastic stratum with hysteretic damping is studied. The stratum, bearing on a rigid...

Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...

Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...

RCC: A Dam Rehab Solution Unearthed
Roller compacted concrete (RCC) is fast becoming a popular material for the rehabilitation of existing dams. Several dams have already been rehabilitated using RCC, and several more RCC...

Simulation of Salt Behavior Using In Situ Response
This paper presents an improved method for simulating the salt behavior. In this method, the governing equations are normalized to the creep function, which represents the transient and...
