Subgrade engineering

Workshop, SWJTU, 2019

I was a teaching assistant of Prof. Xianfeng Liu

In transport engineering, subgrade is the native material underneath a constructed road, pavement or railway track (US: railroad track). It is also called formation level. The term can also refer to imported material that has been used to build an embankment.

Soil mechanics

Undergraduate course, TYUT, 2016

I was a teaching assistant of Prof. Xiaohong Bai

Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids (usually air and water) and particles.
