Seismic refraction, isotropic anisotropic seismic tomography on an ancient monument (Antonino and Faustina temple ad 141)

摘要: This paper describes the results of using geophysical techniques to investigate three columns Pronaos Antonino and Faustina temple (AD 141) in Rome, Italy; are cipollino marble which shows alternate sequences mica calcite beds. We applied seismic refraction traditional interpretation, transmission tomography. The comparison between study 2D 3D isotropic tomographic analyses suggested anisotropic characteristics for marble, this prompted us perform a further experiment, taking into account these material. Assuming an elliptical model, main directions anisotropy were detected. Two velocity fields corresponding measured anomalies such as cracks fractures noted. conjugate-gradient algorithm was used invert data. models compared. correlation methods highlighted i.e. anisotropy, depth weathering, small cracks. show that material is reasonable condition, with exception surface area 6 cm 15 deep we estimate has been weathered 2000 years, particularly affected by pollution last century.
