Despitethissensitivitytothechanges,monitoringhasdemonstratedthatthenatureandmagnitudeofthemovements,evenifprojectedtothefull40yearsofexpectedplantlife,arewithintheestablisheddesigncriteria.IntakeShaftAtthecloseofthemonitoringprogramonlyfiveinclinometers(SI-2,SI-6,SI-8,SI-9andSI-10)remainedaccessibleintheintakeshaftarea.Threeoftheseinclinometers(SI-8,SI-9,RSI-10)weremonitoringtherockmassbetweenthetwocirculatingwatertunnelsandtwo(SI-2andSI-6)arelocatedwestoftheintakeshaft.Themonitoringoftheintakeshaftinclinometershasdemonstratedthreedistincttypesofbedrockmovement;elasticresponsetoexcavationoftheshaftandtunnels,deformationinresponsetorisesinwaterlevels,andtisane-dependentdefor>nation.displacement-depthprofileofinclinometerSI-6(Figure6)whichclearlyshowsthemovementoftherockmassinresponsetotheexcavationofthenorthtunnelatanelevationofapproximately140feet.Atadistanceofapproximately40feetfromthetunneltheinclinometerhasrecordedupto9.75mm(0.384inches)ofmovement.Thismovementinitiatedimmediatelyaftertheexcavationofthatsectionofthetunnel.Becausethistypeofmovementoccursinresponsetoexcavationandtherockmassadjuststothenewstressconditionsbeforeanystructuresarecompletedwithintheexcavation,itisnotconsideredasdeterimentaltothesafetyofthefacility.RiseinWaterLevels:Deformationinresponsetorisesinwaterlevelsareevidentonthetime-dependentplotsofalltheinclinometersthatweremonitoreduntiltheendofthemonitoringperiod.Allshowanabruptriseindisplacementnearthebeginningof1983whentheintakeshaftwasfloodedandmostillustrateasmallincreaseintherateofdisplacementafterJuly1984whenthewaterlevelintheshaftwasallowedtoriseagain.Theincreaseindisplacementrateisoftenabrupt,butgenerallythisratepersistsforlessthantwomonthsbeforereturningtoasteady-levelofnodisplacementorverysmalllongtermdisplacement.Thetime-displacementplotforelevation16l167feetinInclinometerSI-10illustratesthiseffect(Figure29).Afterinstallationinlate1981,SI-10didnotexperienceanysignificantdisplacementalong
