Foundation choice is a cornerstone of soil engineering. The main types include shallow (spread footings, mats), deep (piles, caissons), and specialized foundations for unique soil conditions. Selecting the right foundation relies on accurate assessment of soil properties, load requirements, and site constraints.
Settlement control is crucial. Engineers must evaluate potential settlement risks by analyzing compressibility, bearing capacity, and groundwater conditions. Design modifications, such as increasing foundation size or switching to piles, are often required if initial soil engineering analysis reveals high settlement potential.
Allowable settlement limits are defined by standards and project specifications. If unexpected settlement occurs, foundation redesign may involve underpinning or soil improvement. For example, a major urban transit project in 2025 succeeded only after engineers switched from shallow to deep foundations due to unforeseen compressibility in organic soils.
Earth Pressure and Retaining Structures
Calculating earth pressures is central to soil engineering. Engineers determine lateral pressures—active, passive, and at-rest—based on soil type, slope, and wall height. These calculations guide the design of retaining walls, basements, and bracing systems.
Water presence greatly influences earth pressures. High groundwater can increase lateral forces, requiring careful drainage and waterproofing. Proper backfill compaction is also essential to stability.
Failure data show that a significant number of retaining walls collapse each year due to inadequate soil engineering and misjudged earth pressures. Modeling and simulation tools help predict and prevent such failures, ensuring safer and longer-lasting structures.
Soil Compaction and Field Control
Compaction is a fundamental aspect of soil engineering for controlling settlement and increasing stability. Engineers use various methods depending on soil type, including vibratory rollers for sands and kneading compactors for clays. Laboratory tests, such as the Proctor test, establish optimal moisture and density, while field tests verify compliance.
Advances in automation and real-time monitoring have improved quality assurance. Acceptance criteria in 2026 are increasingly stringent, with digital records and sensor data supporting compliance. Freeze-thaw cycles and shrink-swell behavior are considered in design to prevent future issues.
