Dual-Mesh Three Characteristic Lines Method for Stress Wave Propagation Through a Microdefected Rock Mass with a Thin-Layer Filled Macrojoint

A dual-mesh three characteristic lines method was proposed for stress wave propagation through a microdefected rock mass containing a thin-layer filled macrojoint. The dual-mesh three characteristic lines are composed of five basic elements that are used to calculate stress wave propagation at the boundary and the interior of the microdefected rock mass and the left side, interior and right side of the filled macrojoint. The results of the...
