1. Introduction
This chapter presents a Mobile Slide Monitor (MSM) which can be used for fast geographic
positioning of some objectives or of some of their components that are situated at great
distances from the roadways, (buildings, terrain markings) or are inaccessible in a direct
mode, (dams, bridges, heaps of debris). The system assures an accurate geo-referencing of
the off-road objective characteristics, an important problem for the infrastructure
management at the level of public works administration.
The main applications of this MSM equipment are to estimate and alert, in due time, the
occurrence of great proportion accidents caused by breaking down of civil constructions
(buildings, bridges, tunnels, dams). These accidents are due to natural causes such as
landslides and floods, in the areas with a high risk, or due to some human interventions
such as the erroneous emplacement of some new constructions, the erroneous designing or
even due to the oldness of some constructions.
Moreover, the bridges are part of a country's transportation infrastructure and are typically
assessed and maintained by the authorities responsible for the appropriate transportation
sector (road or rail). Nowadays, the deterioration of bridge structures is a serious problem
due to issues related to modern society; reliance on the automobile, the increased bridge
traffic, the environmental pollution, and the use of potentially corrosive substances (e.g.
cleaning and de-icing). Bridge monitoring is necessary to ensure the safety of those who
either use, or are affected by the structure itself, and the maintenance of the sector is usually
part of the legislature governing.
Therefore the main objective of the present chapter is to describe a mobile laboratory for the
monitoring of constructions deformations in the incipient phases, deformations that are due
