Why is geomembrane used in tunnel engineering? 1. Waterproof protection: geomembrane can play a waterproof role, effectively preventing groundwater, surface water and rainwater from penetrating into the tunnel structure. Tunnel engineering often requires a lot of excavation and groundwater control. Geomembrane can provide a reliable waterproof barrier to avoid water erosion and damage to the

What is the stiffness of geomembrane？ The stiffness of geomembranes is usually described by stiffness index or deflection. Stiffness index is a quantitative parameter of bending stiffness of a material under certain conditions, usually expressed in K value, and the unit is m⁴/N. Deflection refers to the degree to which a material bends when an
