liquepy 0.6.34

Tools for soil liquefaction analysis

Liquepy

Python tools for solving problems related to soil liquefaction

Features

• Triggering:

  • Calculate liquefaction factor of safety according to Boulanger and Idriss (2014)

  • Calculate expected lateral strain and volumetric strain according to Zhang et al (2002)

• Settlement:

  • Calculate foundation settlement on liquefiable deposit according to Karamitros et al. (2013) or Bray et al. (2018)

• Element tests:

  • Calculate the dissipated energy required to liquefy

• Site response analysis

  • Perform equivalent linear site response analysis using the pysra package

Installation

pip install liquepy

Optional modules (sra, fig, spatial) require large third-party dependencies and therefore do not import unless dependencies are satisfied.

to install all dependencies for these optional modules run (example for installing sra dependencies)

pip install liquepy[sra]

Contributors

How do I get set up?

1. Run pip install -r requirements.txt

Code suggestions

• Implementations of published liquefaction methods should be written as calc_<property>_<first_author>[_et_al]_<date>() for two authors include both.

• Plotting and visualisation should be not included in computation objects. Instead plotting functions or objects should receive computation objects as inputs.

Formatting

• Follow pep8 formatting standard (except for line character limit not strictly observed)

• Docstrings written in numpy format

• Tabulated data stored as comma separated or semi-colon separated files (not xlsx or xls)

Testing

Tests are run with pytest

• Locally run: pytest on the command line.

• Tests are run on every push using travis, see the .travis.yml file

To test the docs:

1. Install the check docs package: Run pip install collective.checkdocs

2. Run the check docs package and fix the errors: Run python setup.py checkdocs

Deployment

To deploy the package to pypi.com you need to:

1. Push to the pypi branch. This executes the tests on circleci.com

2. Create a git tag and push to github, run: trigger_deploy.py or manually:

git tag 0.5.2 -m "version 0.5.2"
git push --tags origin pypi

Python 3.10+ and numpy 2.x are required. See pyproject.toml for full dependency and build requirements.

Code style and formatting are enforced with black and isort via pre-commit hooks. To set up development tools:

pip install -r requirements.txt
pip install .[test,maps,sra,fig]
pip install pre-commit
pre-commit install

All code contributions should include complete docstrings and type annotations for public APIs.
