Research on Strength Charcteristic Parameter of Sandy Pebble Soil Based on Different Density and Moisture Content

---

Sandy pebble soil is widely distributed in our country. Lots of studies show that sandy pebble soil makes dynamic behavior not clear due to typical discreteness of gravels and random geometrical distribution. This paper quantitatively analyzes the law of the strength characteristics of sandy pebble tunnel surrounding rock under different density and moisture content conditions through large-scale triaxial tests in laboratory. The Results show that: Initial modulus of sandy pebble soil increases with the accretion of consolidation ratio; When the moisture content of sandy pebble soil stays the same, the larger the density is, the higher the stress peak is; when density of sandy pebble soil stays the same, the stress peak of moisture content in natural state is the maximal; When the moisture content of sandy pebble soil stays the same, with the increase of density, angle of internal friction is greater; With the change of moisture content, angles of internal friction and cohesion force of sandy pebble soil have a mutational phenomenon.
