管道排泄系统的存在使边坡具有良好的渗透性,能有效减小坡体中的渗透力和潜在滑面的孔隙水压力;
When GPDS developed in DCS, the permeability of soil mass would become dramatically larger, and the seepage force of groundwater and pore water pressure on sliding surface would reduce;
若土体中粘粒含量高,则形成管道排泄系统所需的时间长,土体的渗透性也相对较低,反之则所需的时间短且渗透性高;
The higher the clay particle content in DCS was, the longer the time needed for the development of GPDS was, and the worse the permeability of soil mass was;
