<br />• <br />reliable interpretation of the slope behavior; such behavior may comprise <br />no deformations at all, deformations along a distinct failure surface or <br />a creep type deformation of the slope. If the deformations are small as <br />expected at CWI slopes, it may take several months to evaluate them with <br />sufficient accuracy. <br />The instrument performance check printed on the following pages of <br />the output caclulates the initial and current sums of the instrument <br />readings. These should be nearly constant for each accelerometer sensor, <br />but the constant may change with time depending on where the instrument zero <br />is relative to vertical. Change in the instrument zero does not introduce <br />an error into the deflection calculations provided it does not change while <br />actually taking a set of readings. The difference between initial and <br />current sums is also printed in this table; scanning the "sum" and "difference" <br />columns for any large deviations from the constant provides a check on operator <br />or keypunch errors. <br />A tabulation of summary statistics of the sums and differences over selec- <br />ted intervals is plotted on the final page of outNUt. The means of the sums <br />help identify any instrument zero shift with depth and time and the standard <br />deviations indicate how the variability of the data changes with depth and <br />time. <br />INTERPRETATION OF RESULTS <br /> <br />PRESSURE TRANSDUCER INSTALLATIONS <br />Results of water pressure measurements presented in Table 3 indicate <br />that there is no water pressure acting at the locations being monitored. <br />However, it should be noted that ground water was detected in inclinometer <br />boring Il at a depth of approximately 90 feet below the top of casing. This is <br />three to four feet below the interpreted top of bedrock. <br />-6- <br />GEO-HYDRO CONSULTING, INC. <br />
