Geotechnical Grain Size Analysis Report

Report Name: Geotechnical Grain Size Analysis (example ASTM) (example AASHTO)

File Name: EarthSoft.Reports.Library.176839.dll

Dependencies: Licensed EQuIS Geotech and Geotechnical Schema

Software: EQuIS Professional and Enterprise

Source: EQuIS Geotech (EarthSoft Community Center > Products > EQuIS Geotech)

Language: English

Output Type: Excel1 or PDF


Description: The Geotechnical Grain Size Analysis report combines the sieve and hydrometer analysis results and plots a Grain Size Distribution. This report filters the results based on the selected task and will only display samples that have an associated DT_GEO_TEST table record where DT_GEO_TEST.TEST_TYPE = ‘Sieve’, ‘Sieve_Readings’, ‘Hydrometer’, and ‘Hydrometer_Readings’ with the DT_GEO_TEST.TEST_METHOD = ‘ASTM D422’, ‘ASTM C136’, , ‘AASHTO T-88’ or null. This report can be run in EQuIS Professional or published to EQuIS Enterprise.


Installation Instructions: This report requires an EQuIS Geotech license and the Geotechnical Schema applied to the database. The Geotechnical Grain Size Analysis report (EarthSoft.Reports.Library.176839.dll) is available for download in the Products\EQuIS Geotech folder on the Downloads Dashboard on the EarthSoft Community Center. For Enterprise use, this report should be published to the database. When publishing the report, the assembly should be stored in the database. The report will be available for selection once it has been published.


Additional Details:


For the sieve analysis results, this report plots the percent finer value against the sieve diameter size. For the hydrometer analysis, the report plots the percent finer and the associated particle diameter value. Based on the data available, the report calculates the D60, D30, and D10 Coefficient of curvature (Cc) and the Uniformity Coefficient (Cu) values per sample. Each curve on the plot corresponds to one sample.


This report supports task_code based paging.  





The Geotechnical Grain Size Analysis report is designed to use a selected Microsoft Excel template.


Note: The EarthSoft_GrainSizeAnalysis_ASTMD422.xlsx and EarthSoft_GrainSizeAnalysis_AASHTOT88.xlsx template files are provided with EQuIS Geotech. See the Geotechnical Template Configuration article for detailed information on editing/creating Excel templates for use with EQuIS Geotech reports.


In addition to the Shared Attributes detailed in the Shared Report Attributes article, the following Excel Name Manager fields are specific to the Geotechnical Grain Size Analysis report.
