<br />inclinometers are presented in the appendix. <br />In this report, which provides the information on slope deformation <br />for a period of one month, all data from the initial and current inclino- <br />meter readings are presented. A complete set of data for each inclinometer <br />is enclosed for informative purposes. Subsequent reports will include only <br />technically important conclusions obtained during monitoring. <br />PRESENTATION OF RESULTS <br />• <br /> <br />Page 1 of the output for each boring presents the basic numerical data <br />for the baseline ("initial") and most recent ("current") data. The Digitilt <br />inclinometer is a biaxial instrument which is used to measure the inclination <br />of the installed casing in two perpendicular directions at each depth simul- <br />taneously. The A direction is approximately perpendicular to the crest of the <br />slope at the monitoring locations (north-south) since the A accelerometer <br />sensor is the more accurate of both and is therefore chosen to correspond with <br />the most probable direction of movement. The B sensor measures inclinations <br />approximately parallel to the slope crest (east-west). <br />In order to eliminate incorrect readings and maximize accuracy, two sets <br />of A readings (south and north) and of B readings (west and east) are taken, <br />with the instrument rotated 180° between the sets of readings. These <br />readings for both initial and current data, as well as the calculated differ- <br />ences between these readings, are tabulated in the output. The initial and <br />current differences are compared to compute the change in the difference <br />readings at each depth. The deflection of the borehole in inches is then <br />computed by accumulating the differences from bottom to top and multiplying <br />by the instrument constant. <br />The deflection (in inches) and change (in instrument readout units) <br />are plotted against depth for the north-south and east-west directions on the <br />next four pages. For practical purposes, the deflection values (Page 2) and <br />change values (Page 3) for the north-south directions (parallel with the slope <br />dip and perpendicular to the slope crest) are of importance.
