Frost1D 0.1.0 Released

I am happy to announce that Frost1D 0.1.0 is released. Hopefully it can help engineers or researchers for projects in the cold or relatively cold regions.

Frost1D is a one dimensional frost penetration analysis program. It can analyze multi-layered materials with various boundaries. Built-in fine and coarse grained soils, general freezable material and simple material can meet various project requirements.

PyPile 0.4.0 Released

I am happy to announce PyPile 0.4.0 is released today.

With PyPile 0.4.0, users can analyze laterally loaded piles with: 1) axial pile head loads; 2) English units; 3) result graph export to svg, emf, pdf, and png formats; 4) more HP pile types; 5) some other minor improvements.

Please feel free to let me know if you have any questions, suggestions, recommendations, or bug reports. Thank you for your support!

PyPile - 0.4.0

PyPile 0.3.0 Released

I am happy to announce that PyPile 0.3.0 has been released today and available for download from the Download menu.

Multiple piles can be analyzed in one run with PyPile 0.3.0; analysis results for all piles are summarized in one excel file. HP piles are added in the cross section types and the HP pile library is editable for end users. As requested by some users, load generation tool is back on the load dialog. Analysis result can also be viewed in the Result Data tab of the main window next to the Result Graph tab now. Some other minor improvements and bug fixes are also included in this release.

A Mac version is also available for download now.

Create 3D Boreholes

With SoilStats, users can easily create and visualize 3D boreholes using Excel xlsx file or gINT file.

In the case of xlsx file with manually entered data, only four steps are needed:

  1. Copy “SoilStats Xlsx Template.xlsx” to your location and change the file name
  2. Enter data into the xlsx file
  3. Set datamap_soilstats_xlsx.sdm as the default data map file in SoilStats
  4. Open the xlsx file with SoilStats.

SoilStats 0.3.0 Released

I am very happy to announce SoilStats 0.3.0 is now available. The main improvements compared with 0.2.x are duplicated borehole numbers differentiation and multiple data map files incorporation. Some minor improvements and bug fixes are also included.

With SoilStats 0.3.0, users can analyze multiple gINT files with duplicated borehole names from different projects; users also can analyze multiple gINT files generated based on different template files. With these new functions, it turns out to be very easy to summarize existing borehole files from different resources.

In addition, borehole coordinates and elevations are presented in a new view.

SoilStats 0.2.0 Released

We are pleased to announce SoilStats 0.2.0 is released. SoilStats is a tool to analyze gINT geotechnical borehole logs and provide statistical information of the soils. It will help engineers reduce geotechnical report preparation time significantly.

SoilStats 0.2.0 incorporates statistical analysis of water / moisture content, spt N value, pocket pen reading, soil layer thickness and depth, water level depth and Atterberg Limits. SoilStats is able to query soil information from multiple gINT files at the same time, and also can help engineers regroup soil layers for different summarization requirements.

In order to interpret the data correctly, SoilStats will require different data map files for gINT files generated with different templates. Currently there is one example gINT file with its associated data map file in the release bundle. To use SoilStats with your own gINT file, please send your typical gINT file to Yong Technology to create a data map file for you. Creating data map files is free of charge.

PyPile 0.2.0 Released

We are very happy to announce that PyPile 0.2.0 is released. In this release,

1. Multi-layered soil is considered.
2. A P multiplier is added to reduce P value in p-y curves in some use cases.
3. Lateral force and moment can be applied to pile head at the same time.
4. Pile rotation angle output along pile length is added.


GeoRose 0.5.0 – A Free Geological Rose Diagram and Stereonet Plotting Program

We are happy to announce that GeoRose 0.5.0 is released.

With GeoRose 0.5.0, users are able to plot stereonet diagram with plane data and lineation data for both equal area and equal angle projections, . Users can fully control the style of the diagram as in rose diagram plotting mode.

At the same time, polar area diagram is ruled out in this release. If you use GeoRose for roots directions statistics, please don’t update it to 0.5 version.

Your feedback will be very welcome.


Custom p-y curve example in PyPile

Users can customize their p-y curves using JavaScript in PyPile, which provides great flexibility to create p-y curves for any type of soils. The following code is an example to show how to use JavaScript to create p-y curve for stiff clay without free water presence (Reese).

The parameters of this function are specified by users or obtained from current and upper soil layers. The function returns lateral force P based on the deflection y and its user-defined p-y model.

function PyFunction(y, depth, top, bottom, r, r_ave, c, c_ave, phi, e50, k, u0, u1, b, cyclic){
    var P

    var J = 0.5
    var Pu = Math.min((3 + r_ave / c * depth + J / b * depth) * c * b, 9 * c * b)
    var y50 = 2.5 * e50 * b

    if (y < 16 * y50) {
        P = 0.5 * Math.pow(y / y50, 0.25) * Pu
    else {
        P = Pu

    return P
