In this work, we have investigated the steady state temperature field (from linear heat sources - buried cable -) in a different type of soil and excavation geometry. In a laboratory, a physical model was built on scale, which reproduces an "undisturbed" area containing a linear thermal source. This scale model was produced for experimental activity. A measuring chain was made to analyze the thermal field in various types of soils, by varying the electrical current through the line source. The physical model was recreated using a finite volume calculation software. Analysis of the different field system configurations were completed and we have studied a model for the improvement of the design method.</div><div><b>KEYWORDS</b></div><div class="keywords"><a href="https://thermalscience.vinca.rs/keywords/dry+soil">dry soil</a>, <a href="https://thermalscience.vinca.rs/keywords/buried+cable">buried cable</a>, <a href="https://thermalscience.vinca.rs/keywords/FEM+model">FEM model</a>, <a href="https://thermalscience.vinca.rs/keywords/electrical+current">electrical current</a>, <a href="https://thermalscience.vinca.rs/keywords/linear+thermal+source">linear thermal source</a>, <a href="https://thermalscience.vinca.rs/keywords/design+method">design method</a>, <a href="https://thermalscience.vinca.rs/keywords/excavation+geometry">excavation geometry</a></div><div class="dates">PAPER SUBMITTED: 2012-05-28</div><div class="dates">PAPER REVISED: 2013-09-01</div><div class="dates">PAPER ACCEPTED: 2013-09-05</div><div class="dates">PUBLISHED ONLINE: 2013-09-22</div><div>DOI REFERENCE: <a href="https://doi.org/10.2298/TSCI120528119S" target="_blank">https://doi.org/10.2298/TSCI120528119S</a></div><div>CITATION EXPORT: <a href="https://thermalscience.vinca.rs/citation_report/1129/">view in browser</a> or <a href="https://thermalscience.vinca.rs/citation_report/1129/txt">download as text file</a></div><div class="yvi"><b>THERMAL SCIENCE</b> YEAR <b>2015</b>, VOLUME <b><a href="https://thermalscience.vinca.rs/2015">19</a></b>, ISSUE <b><a href="https://thermalscience.vinca.rs/2015/2">Issue 2</a></b>, PAGES [461 - 474]</div><div><a id="slider_button" href="javascript:void(0)">REFERENCES</a></div><div style="overflow: hidden;"><div style="margin-top: 0px;" id="reference_list"><div><ol id="refslist"><li class="refslist">El-Kady, M.
