This is to achieve mathematically predict the dynamic behavior of three-dimensional solid with a rotary kiln with a length of 50 m and weighing on full capacity over 1000 tons. To thwart any occurrence of disorders associated with high mechanical activity of the soil, a specific arrangement of the foundation mass was conducted by use of stochastic calculations.

INTRODUCTION The preparation of maintenance work in industrial plants now has use of study tools, modeling and simulation based on the exploitation of topographical measurements using specific mathematical models [1-2]. These analysis and simulation tools based on3D data are becoming more numerous and powerful [3-4-5]. Since 2008, the company SOCOCIM industries (West African Cement Company) has embarked on a modernization of its production units whose mistress idea is marked by a quest for quality and safety in compliance with environmental provisions force. The objective of this article is to study and translate the dynamic behavior of the massive production chain by use of stochasticcal culations by coupling time series analysis and parametric compensation. II. LOCALISATION OF THE SITE SOCOCIM industries (West African Cement Corporation) are located at the geographic coordinates 14.70° latitude and 17.25° west longitude. Figure 1 : Localisation of SOCOCIM III. METHODOLOGY AND MATERIALS The methodology will be divided into two main parts: i) Data acquisition ii) Presentation and data processing. a. Data acquisition Prior to any collection of surveying data necessary to supply the bank chronic massive dynamic, is the creation of new topographical points of reference, serving as a support for future stations raise and auscultation. III. 1. Implementation of the auscultation network For not working directly on the work, a network of auscultation was implemented. The detection of absolute motions of the structure requires a linking of measuring points of the structure at sufficiently remote auscultation network area susceptible to the furnace operation related movements. The establishment of new points of support is obtained by connecting existing system to the initial reference, which is the basis of previous work. This system is materialized on the ground by two
