Soil and Earthwork Calculator

Soil and Earthwork Calculator contains 60 Calculators for Soil Mechanics, Earthwork, Excavation, Compaction, Footing, Thrust from Soil, Explosion Calculations and Civil Engineering parameters. Available for iPad & iPhone Available in Imperial (USCS) and Metric Units (SI UNITS) Auto-fill Reference Values — select a Soil Type or Surface Material from the built-in picker and all input fields populate instantly with standard engineering reference values Built-in Reference Tables across 5 categories — Soil Properties (19 soil types), Atterberg Limits (15 classifications), Earthwork Materials (18 materials), Equipment Data (9 surface types + 5 scraper models), Water Conditions Smart Pass / Fail Banners — Relative Density, Percentage Compaction and California Bearing Ratio display instant colour-coded classification results (e.g. DENSE, PASS, GOOD / EXCELLENT) after calculation List of 60 Calculators : Water Content of a Soil Sample (Volumetric) Water Content of a Soil Sample (Gravimetric) Void Ratio Degree of Saturation Degree of Saturation (Based on Void Ratio) Porosity Dry Unit Weight of a Soil Specimen Relative Density of Cohesionless Soils (Based on Void Ratio) Relative Density of Cohesionless Soils (Based on Dry Unit Weight of Soil) Plasticity Index Liquidity Index Shrinkage Index Activity Saturated Unit Weight of Soil Dry Unit Weight of Soil Buoyant Unit Weight of Soil Coefficient of Internal Friction of Soil Vertical Stress in Soil (Boussinesq Equation) Vertical Stress in Soil (Westergaard Equation) Coefficient of Active Pressure Coefficient of Passive Pressure Total Thrust from the Soil (Walls retaining Cohesionless Soils) Total Thrust from the Soil (Walls retaining Cohesionless Soils & Surface behind the Wall is Level) Total Thrust from the Soil (Walls retaining Cohesionless Soils and are Completely Restrained) Total Thrust from the Soil (Walls retaining Cohesionless Soils and are Completely Restrained & Surface behind the Wall is Level) Total Thrust from the Soil (Walls retaining Cohesive Soils and are Free to Move a Considerable Amount) Total Thrust from the Soil (Walls retaining Cohesive Soils and are Free to Move a Small Amount) Total Thrust from the Soil (Highly Cohesive Soils) Total Thrust from Water retained behind a Wall Effect of Surcharge on a Wall retaining Cohesionless Soil / Unsaturated Cohesive Soil Stability Number (Slope - Without Seepage Water) Stability Number (Slope - Seepage of Water) Ultimate Bearing Capacity of Soil (Prandtl's Equation) Relationship between Loads on Foundations and Settlement Volume of Soil Percentage of Moisture Content in Soil Field Density of Soil Dry Density of Soil Percentage of Compaction of Soil Scaling Factor (Load-Bearing Test) California Bearing Ratio Flow Rate Compaction Production Rolling Resistance (Earth Moving) Grade Resistance (Earth Moving) Total Road Resistance / Total Pull (Earth Moving) Volume of Soil after Excavation Volume of Soil after Compaction Scraper Production Trips per Hour (Scraper) Amount of Material carried by a Machine Production Required Number of Scrapers needed on a Job Number of Scrapers a Pusher can Load Variable Time Wavelength of Vibration during Explosion Velocity of Particles distributed by Vibration during Explosion Acceleration of Particles distributed by Vibration during Explosion Overpressure due to Explosion Sound Pressure Level
