مسح زلزالي انكساري ثنائي البعد لمشروع المستشفى التعميمي في جامعة الموصل

Abstract EN

The study includes seismic refraction tomography, along 12 traverses with a total area of 35140m2, for the Teaching Hospital Project at Mosul University.

The aim of the study was to detect the thickness and types of the different subsurface layers.

The survey conducted by the Swedish ABEM Terraloc Instrument.

The data processed and presented as tomography sections by SeisImager/2D Program Packages.

The study shows the presence of three different subsurface layers.

The first layer represents the topsoil layer having velocity ranges between (350 m/sec-700 m/sec), and thickness up to 3.2m.

The second layer having velocity ranges between 840-1700m and thickness between (3m-14.7m), mostly representing the river deposits, composed specially of river terraces and clays.

The third layer was having velocity ranges between (1900 m/sec-2800 m/sec) and depth ranges between (3.0m-17.9m) representing the hard bed, which is mostly composed of marl layers belong to the upper part of Fat’ha Formation.
