28 - Using RSLog Cross Sections in Slide2

1.0 Introduction

RSLog allows you to log test holes for soil and rock, in geotechnical, environmental, oil and gas, or mining projects. A feature of RSLog is the ability to design a cross section with your field data. This cross section can be easily imported into Slide2.

In this tutorial you will learn how to:

• Create a cross section in RSLog
• Bring the section into Slide2 using your RSLog account (online)
• Bring the section into Slide2 by uploading a file (offline)

2.0 RSLog Project

On your web browser, go to the RSLog login page: https://www.rslogonline.com/ Login with your credentials.

We will be importing the RSLog project from Excel. To do this:

1. On the left-hand side, select Data Entry > Import.
   
2. Under RSLog Excel Templates, click Import Data.
   
3. Next to Choose Project Excel File, click Browse.
4. Navigate to this path in the Tutorials folder: C:\Users\Public\Documents\Rocscience\Slide2 Examples\tutorials\Tutorial 28 RSLog Import Data
5. Load in “ProjectTemplate.xlsx.”
6. Now next to Choose Test Hole Excel Files, click Browse.
7. In the same directory, select all the “Testhole_....xlsx” files and load them in.
8. Select Import Data.
   

Once done, you will be taken to the Test Holes project page:

Three test holes have been defined for this project. You can double-click on each test hole to see more information.

Notice the name of the active project “Slide2 Tutorial” in orange at the top of the page.

3.0 Create Cross Section in RSLog

We will create a simple cross section between boreholes 1 and 2:

1. Select Data Entry > Cross Section.
2. In the map, single click on AH20-1. Make sure to click in the center of the blue symbol.
3. Double click on AH20-2 to finish defining the cross section.
4. In the pop-up, name the section “Slide2 Section.”
5. Click Save.

The new section will appear on the list. Click Open. By default, you will see the two test holes as well as a legend indicating the materials in each borehole. The legend can be moved out of the way by clicking and dragging.

We will design a simple cross section as follows:

1. Select the “Draw Soil / Rock Layer” icon at the top.
   
2. Starting with the left borehole (AH20-1), and the bottom layer, click on the vertex labeled 29:
   
3. Now scroll over to the second borehole by clicking and dragging, and click on vertex 18. Then click on vertex 33:
   
4. Now return to the first borehole and click on vertex 35. Press Enter.

We will assign the appropriate material to this layer.

1. Click on the black polygon.
2. In the Object Properties on the left side, under Polygon, change the following:
   1. Fill Style = Pattern.
   2. Pattern Type = TILL.

Your screen will look as shown:

Using the same methodology, you can match the materials in the left borehole to those in the right borehole to design the section with the knowledge you have available. However, we will leave this as an optional exercise. For more information on defining cross sections in RSLog, see Cross Section Overview in the RSLog help.

For the sake of consistency in this example, we will use a predefined cross section.

1. Click Save to close the Slide2 Section.
2. Open Tutorial Cross Section.

Your screen will look as shown:

4.0 Import Cross Section to Slide2 (Online)

We will now import this section into Slide2 as a soil profile. To do this:

1. Launch Slide2.
2. Select File > Import > Import RSLog Cross Section or use the toolbar icon .
3. Select Import from RSLog Account and click Next. You will see the dialog below:
   
You can import cross sections either by logging into your RSLog account (online) or by importing a file saved to your machine (offline). We will use the online method. See the end of the tutorial for details on the offline method.

4. Input your credentials in the dialog and click Next.
5. You will now see the list of projects in your account. You can click on each one on the left side to see general details about each project.
6. Select Slide2 Tutorial on the left side and click Next.
   
7. You will now see the two cross sections defined for this project. Click on each one to see the preview image of each section.
   
8. Select Tutorial Cross Section.
9. Notice the Import as Soil Profile checkbox. By default, this is on, since the user would most likely need to cut the slope out of their cross section in Soil Profile mode. If you want to import the cross section directly as a slope, you can uncheck this box.
10. Click Finish.
11. The display units of the cross section are imperial whereas the units of the Slide2 project are metric. Click OK in the message to automatically switch the units in Slide2 to imperial. Click OK again in the units message.
12. You will see the cross-section as shown:

Notice that the colours are imported from the RSLog section. Select Properties > Define Materials. The materials displayed are named after the selected hatch. All materials are default Mohr-Coulomb and will need to be defined by the user. Click Cancel.

We can now cut the desired slope out of the section:

1. Select the Geometry workflow tab.
2. Select Boundaries > Add External Boundary.
3. Click Add External as Polyline.
   
4. We will define the external with a coordinate table. Type t in the command line and press Enter. Copy and paste the coordinates shown:

1	10
1	7
1	0.5
1	0
200	0
200	0.5
200	6
200	6
200	10
200	11
180	13
165	13
112	16
68	22
58	27
1	27

5. The table will look as shown:



6. Click OK.
7. Press Enter to finish defining the external.

Your model will look as shown:

The user can then proceed with material property definitions and compute the analysis. This concludes the tutorial.

5.0 Import Cross Section to Slide2 (Offline)

The above example demonstrates the import of the RSLog cross section by logging into your RSLog account. If you won’t have internet access while making your Slide2 model, you can export the RSLog section ahead of time as follows:

1. In RSLog open Tutorial Cross Section.
2. Click on the Export button at the top and select “Rocscience Section (JSON)”. This downloads a Rocscience Section file.
   
3. In Slide2 select File > Import > RSLog Cross Section.
4. This time, select Import from File and click Next.
   
5. Click the Browse button.
6. Select the file you downloaded in step 2 above and click Open.
7. This will import the file in soil profile mode.
