CELE Geotechnical EngineeringSlope Stability and Soil ImprovementSlides

Slide deck for CELE Geotechnical Engineering — Slope Stability and Soil Improvement. These slides are built for quick visual review, highlighting the key concepts, formulas, and question patterns from this chapter of the CELE 2026 syllabus.

Exam context

For the Civil Engineer Licensure Examination, Professional Regulation Commission (PRC) — Board of Civil Engineering tests Geotechnical Engineering under a "Core" label, with Slope Stability and Soil Improvement in the 11th slot across 11 chapters. CELE candidates must clear the 70% weighted average, no sub-test below 50% cut on the 2026 paper, which draws about a meaningful share of Geotechnical Engineering questions. Date to watch: May and November 2026.
