Abstract:MultiplesetsofstructuralplaneswerefoundontheleftbankslopeoftheHuangjinxiaWater
ConservancyProjectduringtheconstructionperiod.Themonitoringdatashowedthattheslopehadmulti
pledeformationmutations ,andmostofthedeformationoccurredintherangeof20-30m,withthemax
imumintervaldisplacementdetectedbythemultipointdisplacementmetersexceeding80mm.Regarding
tothisproblem ,thedeformationcharacteristicsofsloperockmassarecomprehensivelyanalyzedfromthe
aspectsofspatiotemporalvariationlaw ,eigenvaluestatisticsanddisplacementrate,basedonthemonito
ringdataofthemultipointdisplacementmeters.Theresultsshowthatblastingexcavationandstructural
planesarethemainfactorsleadingtolargedeformationoftheslope;themaindeformationzoneofthe
slopeisconsistentwiththepositionofthestructuralplanesoffz39 ,L920andfz15,sotheslopedeforma
