Formation Mechanism and Mechanical Properties of Soil‐Rock Mixture Containing Macropore [PDF]

Advances in Civil Engineering, 2018
In southwestern China, soil‐rock mixture containing macropore (SRMCM) is very common in large‐scale accumulation slopes. The formation mechanism and mechanical parameters of SRMCM play an important role in slope stability. In this paper, we designed a new physical model test to study the formation mechanism of SRMCM.
