Description
For drainage pipes with slits installed in the soil, it is generally known that drainage from the pipe will not occur unless the soil around the pipe approaches saturation and the pore pressure becomes positive. However, it has been found that in a slope stabilizing method using a geocell filled with crushed stones and a steel drainage pipe with slits, drainage from the pipe occurs with rainfall and snow melting, even though the pipe is installed above the groundwater level. Therefore, in this study, two types model tests were carried out focusing on geocell layers filled with crushed stones placed on the slope surface, and the role of geocell layers and the conditions for occurring drainage from pipes were examined in detail.
