1.1.This practice  provides instructions  for installation,   monitoring,  and data reduction for the traveling type slope inclinometer  for use with guide casing.

A slope  inclinometer  is a precision   instrument that  measures lateral displacement  of a guide  casing resulting from the movement of earth, concrete, or other masses.

This type of instrument  can be used  to detect and monitor movements in earth- and rock-fill dams,  highway embankments and foundations,  excavation slopes,  sheet pile bulkheads, concrete retaining walls, and other structures.

Since the instrument  is waterproof,  it can be used on projects where normal  measurements  would not be feasible,  such as the displacement of the lower portion of a pipe  pile.

The data, which are well suited for computer reduction,  can be used to interpret shear zones in landslide    areas and as a basis  for predicting impending shear

failures   or structural failures  based  on the amount and rate of lateral deformation  occurring.

1.2. The practice is  divided into  the following parts:

1.2.1. Part I, Installing  Slope Inclinometer Guide  Casing;

1.2.2. Part II, Monitoring Slope Inclinometer  Guide Casing;  and

1.2.3. Part Ill, Data Computations and Analysis.

1.3.The values stated in SI units are to be regarded as the standard.
