Study on the Failure Surface of Heterogeneous Soil at the Passive State

Study on the Failure Surface of Heterogeneous Soil at the Passive State

Earth pressure problem is one of the key research subjects in soil mechanics and geotechnical engineering. Heterogeneous soil is always encountered in engineering practices. However, the classical Rankine and Coulomb’s earth pressure theories don’t take into account of the effect of heterogeneity on...
