  • Conventional drainage hole technique used in geotechnical engineering is often encountered with mud or sand-induced drainage jamming.After jammed with mud or sand,the drainage hole will not have its normal function of long-term and effective drainage.For this reason,the authors present a new drainage technique of long-term drainage efficiency,i.e.fiber bundle seepage-guiding drainage hole technique.Seen from laboratory tests of comparisons,the purpose of long-term and effective drainage can be realized by using the new technique,even for an occurrence of mud or sand-induced drainage jamming.Compared with conventional drainage hole,the new-type drainage hole has the almost same cost,having a broad application foreground in geotechnical engineering.
