Introduction

Provide your engineers with instant access to laboratory test results. SoilVision provides the most advanced reporting and analysis options of any database system available. Soils data is stored on a globally standardized database single-file format. SoilVision is also compatible with industry standards of testing for the following tests:

Sieve analysis (ASTM D422-54T)
Consolidation tests (ASTM D4546)
Isotropic triaxial tests (Critical State)
Triaxial tests for shear strength (Bishop and Henkel, 1962)
Shear box tests for shear strength (Bureau of Public Roads, Washington, D.C.)
Standard and Modified Proctor compaction tests (ASTM D698)
Dozens of methods of measurement of the soil-water characteristic curve
Several methods of measurement of saturated hydraulic conductivity as well as hydraulic conductivity as a function of soil suction or void ratio
Soil shrinkage (ASTM D427)
Saturated coefficient of diffusion and diffusion as a function of soil suction
Unfrozen volumetric water content as a function of temperature
Thermoconductivity as a function of soil suction
California Bearing Ratio (CBR) ASTM D 1883
Standard Penetration Test (SPT)
Cone Penetration Test (CPT)

Volume-Mass Properties

Calculation of proper volume-mass properties is provided in SoilVision to simplify management of soils data. SoilVision allows the input of almost any three insitu volume-mass properties (i.e., water content, dry density, and specific gravity) and calculation of all remaining volume-mass properties will be performed.

Classification

Automatic classification of your valuable soils data allows proper grouping of soil properties. Interested in the average saturated permeability of silty loams? Automatic classification ensures the integrity of your database.

Features:

Automatic classification by the USDA or USCS (ASTM) classification methods
Plotting of the classification of single soils or groups of soils

Mineralogy

Often a sieve analysis does not provide sufficient insight into the behavior of a soil. SoilVision accommodates the additional detail by providing the functional capabilities to manage the mineralogy of a particular soil. Plotting of the mineral percentages for a soil is also provided.

Soil-Water Characteristic Curve

SoilVision is the only commercially available database in the world capable of managing unsaturated soil properties. Advance into unsaturated soils with ease! The database functionality will manage your soil-water characteristic curve laboratory data in a simple, straightforward manner. Interested in performing unsaturated soils analysis without the high cost of extensive laboratory tests? Pick from seven theoretical estimations to estimate a soil-water characteristic curve or select a similar soil-water characteristic curve from our experimental database of over 6000 soils.

New Features:

Seven pedo-transfer functions for estimating the soil-water characteristic curve including methods from Fredlund & Wilson, Gupta & Larson, Arya & Paris, Tyler & Wheatcraft, Vereecken, Scheinost, and Rawls & Brakensiek
Calculation of volumetric air content as a function of soil suction
Enhanced plotting
Professional report generation
Support for English and Metric units

Features:

Non-linear curve-fitting of soil-water characteristic curve with five different equations including van Genuchten, Fredlund & Xing, Gardner, Brooks & Corey, Mualem, and Burdine
Experimental dataset of over 6000 laboratory measured soil-water characteristic curves
Automatic calculation of variables such as the air entry value, wilting point, and field capacity of a soil
Management of wetting and drying data
Estimation of the soil-water characteristic curve by the Fredlund & Wilson pedo-transfer function
Calculate water storage function necessary for seepage modeling
Comprehensive querying capabilities

Application:
