AI Technical Summary
Existing plate load testing devices are difficult to operate in confined spaces, and have poor versatility and reusability, making them unsuitable for testing trench foundations of different widths.
A plate load testing device was designed, comprising a lateral pressure component, a support component, a reaction component, and a loading component. By adjusting the lengths of the support and reaction components, the lateral pressure component can be pressed against the trench sidewall, the loading component applies the load, and the reaction component transfers the load to the foundation. The bearing capacity and deformation parameters are measured.
The plate load testing device has been improved in terms of versatility and reusability, making it suitable for testing trench foundations of different widths, simplifying the operation process and improving the accuracy of the test results.
