CPT-pro - Powerful CPT graphing and interpretation software for Geotechnical Engineers

Transcription

1 CPT-pro - Powerful CPT graphing and interpretation software for Geotechnical Engineers CPT-pro is a multi-module program designed for complex analysis, interpretation and presentation of CPT soundings, and also for elaborating geotechnical documentation. Methods of CPT sounding interpretation along with formulae and graphs have mostly been extracted, with the knowledge and consent of the authors, directly from the monograph of: Lunne, T., Robertson P.K. and Powell J.J.M. Cone Penetration Testing in Geotechnical Practice. Published by Blackie Academic & Professional PROGRAM STRUCTURE AND FUNCTIONS CPT-pro consists of six modules: 1. [CPT Explorer] for managing CPT data, containing: - Browser with directory tree - Map Project structure (tools and tree) - Thumbnails with charts of selected parameter - Header info with full selection of text - Quick zoom CPT Explorer window

2 2. [Interpretation] module: Sounding log with result of classification on Robertson s chart.

3 Main features and options of Interpretation module: Creation of sounding sheets with basic parameters and results of interpretation Import CPT data of many different formats, including exchange formats AGS and GEF Conversion to Exchange formats AGS and GEF Analysis and correction of sounding results Classification and evaluation of soil parameters Interpretation and presentation of sounding results Presentation of soil samples Presentation of open pipe piezometers Export charts to DF format Sounding log with piezometers Manual filtering of CPT data. Removing unreliable measurements.

4 Formula Editor An add-on powerful Formula Editor allows user defined interpretation functions. Most of mathematical functions available. Evaluations implemented in Interpretation module. Next ones in preparation.

5 Different unit systems. All parameters can be presented in freely chosen unit system. Batch processing Batch processing settings window. This option allows batch interpretation and reduction of as many CPT files as necessary. Additionally, completion of all descriptions (Location, project name etc.) is available at the same operation.

6 3. [Data Editor] NEW! for creating database containing information on User s borehole logs and geotechnical parameters which have structure [Value vs. Depth]. All results are saved in local database, however, due to structure of Data Editor, database file can be shared in local network. Project structure included in Data Editor enables grouping of data sets, so data managing is very easy and effective. Each log and parameter value should include co-ordinates, thus it can be automatically presented on map generated with Map module (as relevant symbol with description) and on geotechnical cross section generated with Cross Section module (borehole log as a soil stick with symbol/color filling and parameter as a graph). Borehole log edition. All descriptions (soil type, consistency, moisture content etc.) are selected from User defined lists (see below), so adding new borehole logs to database is very efficient. Each soil layer can be saved in database with own graphic symbol and color, which are used on cross sections as a filings of soil sticks. Water level values (initial and stabilized) are saved in database and can be presented on section with Cross Section module.

7 User defined list with colors Geotechnical parameter edition. All geotechnical parameters which have a structure [Value vs. Depth] can be saved in the same database as a relevant values connected to investigation hole. Soil type description of such hole is not required, so parameters can exist only as a values on certain depths. Graphs of parameters can be automatically included to geotechnical cross sections generated with Cross Section module.

8 4. [Cross Section] for creation of geotechnical cross sections in any vertical and horizontal scale, containing: Charts/diagrams of CPT parameters Interpretation results of soil classification in the form of standard geological soil bar Borehole logs from external sources (see Data Editor module) Interpretation results of values of selected soil parameters in the form of charts of such parameters Graphs of external soil parameters Graphic objects representing separate geotechnical layers and structures Presentation of soil samples Additional description and comments Additional graphic objects Cross Section window Cross section scales, vertical and horizontal, can be selected independently and arbitrarily. Built-in graphic functions enable saving executed cross sections in *.WMF and *.EMF files which, in turn, enable pasting executed drawings into other graphic programs, text editors and AUTOCAD, MICROSTATION type programs, etc.

9 5. [Map] enables presentation of CPT and VANE tests on map. Location of tests and other objects (boreholes, dynamic soundings etc.) is generated automatically, based on co-ordinates saved in CPT and VANE data files. Both vector (DWG, DF) and image files (BMP, JPG, etc.) can be used as background. Map module is available in two versions LT and Extended. Version Extended includes all necessary tools for edition of vector drawing (DWG and DF formats). Own vector maps grounded GPS surveys can be created. CAD graphics of Map module. The Map module allows to run the following tasks: To provide automatic display of selected CPT sounding, VANE-type tests, other soundings (SPT, DPT etc.) and boreholes as appended to the map project (see C ) against a background of area map. Vector maps in DWG and DF formats as well as maps stored as graphical files BMP, JPG, TIF etc., may be used as the map background. To run full editing of vector maps stored in DWG and DF formats (the option available in Extended version only). To create DWG or DF customer s own vector maps (the option available in Extended version only). To print out the map on any printing device operating within Windows System.

10 6. [VANE] for reduction and interpretation of VANE shear test and creating logs of soundings. Rod friction can be easily estimated just by moving crosshair cursor and taken directly to evaluation of shear force. Sounding log can be freely customized. It can include user defined number of vertical graphs with following parameters: shear force maximum torque rod friction both, for undrained and remoulded tests. Additionally, it can include horizontal graphs with results of individual tests vs. angle or time. VANE sounding log with menu [Settings] and interpretation results Each individual test can be plotted vs. angle and vs. time, depending on data file. Each graph include automatically generated info on depth of test and calculated values of basic parameters. Single shear at chosen depth.

11 7. [Sample Database] for creating databases containing information on soil samples collected and results of their laboratory tests. Samples collected, taking into account their locations and lengths, are presented on sounding sheets and cross sections in [Interpretation] and [Cross Section] modules respectively. Entry into sample database occurs directly from a sounding sheet and cross section using the mouse pointer. Sample database module window Presentation of samples in cross section (red bars)
