Model test and particle flow numerical simulation of soil arching effect for unsaturated sandy soil tunnel

Model test and particle flow numerical simulation of soil arching effect for unsaturated sandy soil tunnel

The apparent cohesion caused by matric suction makes the mechanical properties of unsaturated sand significantly different from those of dry sand. In order to study the soil arching effect of the unsaturated sand tunnel, trapdoor tests with different water content and buried depth were carried out....
