Structures

The Rock Mass Data module allows you to import and analyse oriented structures from boreholes (Televiewer or core logging) and from mapping (drift mapping, digital mapping, photogrammetry, etc.)

Structures Overview

Supported Data Types

• Scanlines
• Boreholes (televiewer, core logging)
• Drift Mapping
• LiDAR / Photogrammetry
• Discontinuity orientation, size, and conditions

CSV TEMPLATES FORMATS and DATA TYPE

• Files imported must be in .csv format (auto-import with customised features OR manual csv import)
• Where there is no data available for the remaining columns leave blank.
• Columns in the .csv file must be in the order specified in the sections below.
• Columns in the specified format, according to this colour code:
  • Number column (green)
  • Text column (blue)
  • Specific Text column (category) - (orange)
  • Date column : yyyy-MM-dd (red)
  • Point columns : X Y Z (3 number columns) (pink)

Key Features

Auto-import of database or manual csv import or webform for scanline

Manual csv Import borehole structures (Core logging or televiewer):

remarque

Alpha and beta angle from core logging can be converted to dip /dip direction with help of a core stick illustration, see the end of the video.

Manual csv Import scanline data:

astuce

You can also import scanline data from webform (https://webforms-demo.mxrapservers.com/rockmassdatacollection/index.html#/):

If you are interested into this webform, please email us.

Manual csv Import drift mapping

Please follow the same process then from boreholes, but using the Drift Mapping window.

• True spacing statistics for each defined discontinuity set

• Visualise and correct for orientation and sampling biases.

Discontinuity Set import and modification / assignment on stereonet with real-time updates to set statistics

Structures plotted along boreholes based on discontinuity set

Poles plotted on stereonet based on discontinuity set

Core logging: Alpha and beta values imported from structural logs can now be converted to dip and dip direction,

The user is required only to provide details on how the beta angle was measured. A core stick illustration is also provided to assist with choosing a beta measurement option.

• Filters: lithology, geotechnical domains, structures type, length, dip, dip direction, etc.

Visualized in 3D the structures with their measured size or specific size per structure type

Down-the-hole analysis and comparison of two data sources from same boreholes (orientation, frequency, etc.)

FAQ

Q1: What happens if I import the same borehole twice?

A1: For automatic inputs, the duplicates will remain - you need to ensure that your database is clean. For manual csv import, if you try to import a borehole that already exists, the new data will overwrite the old one for the whole borehole.
