Sarma法的改进及在边坡稳定性研究中的应用 Sarma'sMethodanditsImprovements:ApplicationsinSlopeStabilityStudies Introduction: Thestabilityofslopesisacriticalfactorinengineeringprojectsandcandeterminethesafetyandsuccessofinfrastructure.Thestudyofslopestabilityhasseensignificantdevelopmentsovertheyears,drivenbytheneedforaccuratepredictionsandanalysisofpotentialfailures.OnesuchdevelopmentistheSarmamethod,whichhasbecomeapopularapproachinslopestabilityresearch.ThispaperaimstoexploretheSarmamethod,itsimprovements,anditsapplicationsinthefieldofslopestability. OverviewoftheSarmaMethod: TheSarmamethod,developedbyDr.Sarmainthemid-1980s,isadeterministicapproachthatfocusesonthefactorofsafetyinslopestabilityanalysis.Themethodtakesintoaccountvariousparameters,includingsoilproperties,groundwaterconditions,andslopegeometry,topredictthestabilityofaslope.AlthoughtheSarmamethodisrelativelysimpleandeasytoapply,ithasitslimitations,suchasassuminglinearvariationsofsoilpropertiesandneglectingtheeffectsofporewaterpressure.
