In Situ, Nonlinear Soil Response Applying an Active Source
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
Soil sites have a profound effect on ground motion during earthquakes due to their low wave
speeds, layered structure, and nonlinear constitutive relationship. Measurements of nonlinear soil
response under natural ...
Numerical Modeling of Transport Properties and Comparison to Laboratory Measurements
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2008-06-10)
Transport properties, such as permeability and electrical conductivity, are important in many
geophysical and petroleum applications. The microstructure of a porous medium and physical
characteristics of the solid and ...
Finite-Difference Simulations of Time Reversed Acoustics in a Layered Earth Model
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2007)
Traditionally an earthquake is located by using the arrival times of P and S phases. This uses only a limited portion of the information on a seismogram. A large part of the information carried by the waveform is not used. ...
A Numerical Study of the Effects of Wave-Induced Fluid Flow in Porous Media: Linear Solver
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
In this paper, we present a computational method to simulate wave propagation in porous rocks saturated
with Newtonian fluids over a range of frequencies of interest. The method can use a digital representation
of a rock ...
Pore Scale Modeling of Rock Properties and Comparison to Laboratory Measurements
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
The microstructure of a porous medium and the physical characteristics of the solid and fluid
phases determine the macroscopic transport properties of the medium. The purpose of this paper
is to test numerical calculations ...
