Hdpe Gecell is a three-dimensional reinforced flexible material that enhances the bearing capacity of composite structures and reduces deformation through friction, lateral constraint, and mesh effect. It is widely used in soft foundation reinforcement, slope stability, and reinforced retaining wall engineering When the geocell is in long-term service, internal water seepage will gradually loosen the strip of the geocell, causing significant deformation of the entire geocell and weakening its ability to suppress soil displacement, thereby affecting the quality of reinforcement. Therefore, in some engineering applications, the geocell will be perforated to achieve lateral drainage However, there is relatively little research on the reinforcement effect of perforated geogrids both domestically and internationally, and the current situation where engineering practice takes priority over relevant theoretical research affects its promotion and application in the construction field
