Transparent Soil Testing Platform HC-PIVTS

System Description

Transparent soil experimental technology covers the preparation of transparent soil, testing of its geotechnical engineering properties, supporting experimental equipment and techniques, as well as image capture and processing methods. A prerequisite for research using synthetic transparent soil is that it exhibits geotechnical properties similar to those of natural soil. By combining transparent soil with modern optical observation, image capture and processing techniques, visual research can be conducted on three‑dimensional deformation, strength and seepage characteristics of soil. This is of great significance for in‑depth investigation of internal soil deformation mechanisms under various engineering geological conditions and for advancing fundamental understanding of soil mechanics and geotechnical engineering problems.

This testing platform performs experiments using transparent soil to simulate real soil conditions. Through three‑dimensional reconstruction of soil samples via PIV technology, high‑precision 3D visual images are obtained to reproduce actual engineering scenarios. The system consists of three modules: transparent soil preparation, model test loading, and image acquisition and processing. It enables non‑contact, visual measurement of the internal displacement field of soil. The model test system can be applied to simulations of subgrade and pile foundations, slopes and excavations, tunnel engineering and other scenarios, featuring high precision and reliable performance.
