What are the common problems in soil mechanics construction? I hope to have an expert to answer it, and I am very grateful! ! !

Soil mechanics often meets in construction:

1. Identification of soil;

2. Calculation of soil bearing capacity;

3. Calculate the compactness of soil (ring knife method, irrigation method and sand filling method);

4. Determine the engineering properties of soil by in-situ testing method.

This is the first person's view on geology, rocks and soil.
