Scope
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. Because 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. The practice is divided into the following parts: Part I@ Installing Slope Inclinometer Guide Casing; Part II@ Monitoring Slope Inclinometer Guide Casing; and Part III@ Data Computations and Analysis. The values stated in SI units are to be regarded as the standard.
