Abstract

This section summarizes the calculation formulas for laboratory tests of soil and rocks together with the basic requirements of each calculation into a set of tables. This section covers the most commonly used tests for soil, such as water content (Table 8.1), density (Table 8.2), specific gravity of soil solids (Table 8.3), particle size distribution (Tables 8.4 and 8.5), Atterberg limits (Table 8.8), relative density of sand (Table 8.9), California Bearing Ratio (CBR) (Table 8.10), modulus of resilience (Table 8.11), penetration (Table 8.12), consolidation (Table 8.13), collapse characteristics test of loess (Table 8.14), triaxial compression (Table 8.15), unconfined compressive strength (Table 8.16), compaction (Table 8.17), direct shear under consolidated-drained conditions (Table 8.18), reversal direct shear strength (Table 8.19), tensile strength (Table 8.20), Free swell test of clay (Table 8.21), swelling ratio (Table 8.22), swell pressure (Table 8.23), shrinkage (Table 8.24), soluble salt content (Tables 8.25–8.31) and organic matter content (Table 8.32), and those for rocks, such as water content (Table 8.33), grain density (Table 8.34), density (Tables 8.35–8.37), absorption (Table 8.38), slake durability (Table 8.39), swelling properties (Table 8.40), uniaxial compressive strength (Table 8.41), durability under freezing and thawing conditions (Table 8.42), the deformability in uniaxial compression (Table 8.43), the strength in triaxial compression (Table 8.44), the indirect tensile strength by Brazil test (Table 8.45), the shear strength of rock joints (Table 8.46), point load strength (Table 8.47), the sound velocity test by ultrasonic pulse transmission technique (Table 8.48) and rebound hardness test (Table 8.49).
