- Abstract:
- Geogridcanimprove the tensile strength，shearstrength andoVemll stabilitysignificantly when it is used as reinforcementfor ground．Basedonthe discreteelementmethod software PFC2D，anumericalmodel is established to studythegeogrid reinforced soil．Compared with unreinforced soil，thefoUowing studies are ped．onned：the settlement of fbundation and the lateml and Vertical displacement distribution of soil with depth．Then，aparametric studyis carried outto investigate the bearingcapacity of fbundationandthe select— ed innuencing factors consist of the reinforced length，reinforced depth andthe number of reinforced layerS．Theresults show that the geogrid can reduce the foundation senlementandimprove tlle bearing capacity．It can restrict the ground horizontal and vertical displacement efkctiVely．The optimal pammeters of reinforced lengtII，reinforced depth andreinforced layers are 3曰、0．25曰and2 1ayers respectiVely．
