If you only have access to a corrupted scan, you can attempt to create your own fixed version using free tools:
Note: This is time-consuming. If your time is worth more than $10, simply buy the official e-book. These cover similar content for civil engineering geology:
The keyword "fixed" is crucial. Why? Because the majority of freely circulating PDFs of Varghese’s book are second- or third-generation photocopies. Here is the typical damage:
Thus, a "fixed" PDF implies one that has been:
Chapter 15 contains a workflow diagram for tunnel alignment that is often missing in scanned copies. It instructs engineers to avoid crossing fault zones at an angle less than 45 degrees. Without this diagram, you might route a tunnel directly into a landslide-prone shear zone. If you only have access to a corrupted
Many broken PDFs misprint the RQD formula. Varghese correctly states:
RQD (%) = (Sum of length of core pieces > 10 cm / Total length of core run) × 100
A corrupt PDF might omit the "> 10 cm" condition, leading to gross overestimation of rock mass quality on site. Note: This is time-consuming
Print + scan your own – If you own a physical copy, scanning it to a searchable PDF (using OCR) is perfectly legal for personal backup. Tools: Adobe Scan, Microsoft Lens, or a sheet-fed scanner.
Interlibrary loan – Many libraries will scan a chapter or two for research/study if a digital version exists.
Note: “Fixed PDF” usually refers to correcting missing pages, broken OCR, skewed scans, or garbled text from a badly digitized copy. If you already own a poor-quality scan, you can clean it up with Adobe Acrobat Pro (enhance scans, run OCR), ABBYY FineReader, or free tools like OCRFeeder + ScanTailor.
