He presented his findings to the chief engineer. “We need horizontal drains and a retaining wall with weep holes,” he said, pointing to the textbook’s Figure 9.3. “Otherwise, the next cut will bring down half the hillside.”
The engineer scoffed. “We don’t have time for academic theories.” parbin singh engineering and general geology pdf
Parbin Singh adjusted his hard hat and knelt beside the exposed rock face. In one hand, he held a weathered copy of Engineering and General Geology — the very book that had guided him through countless projects. The Ghat road expansion was behind schedule, and two days of monsoon rain had triggered a small landslide, killing a worker. The contractor wanted to simply clear the debris and resume blasting. But Parbin, a young site geologist, had his doubts. He presented his findings to the chief engineer
That evening, Parbin borrowed a theodolite from the survey team and measured the dip and strike of the joints. He sketched a stereonet on a piece of tracing paper, just as Professor Verma had taught him in college. The numbers confirmed it: a planar failure surface with a factor of safety below 1.1 in wet conditions. “We don’t have time for academic theories
The next morning, work stopped. The design was revised. Three weeks later, during a record-breaking downpour, the slope held — while an adjacent site, which hadn’t followed the same precautions, collapsed into a muddy scar.
But Parbin didn’t back down. That night, he drove to the nearest town, scanned the relevant pages from his precious PDF copy of Engineering and General Geology , and emailed them to the project director with a risk analysis. The director, a former student of Parbin Singh (the author), recognized the approach immediately.
