Structural Deformation Surveying – Part 2 **Home Study**

Description

Authur: Bernabe A Hernandez, Ph.D, PE, PLS

This seminar provides technical guidance for performing precise structural deformation surveys of hydraulic flood control or navigation structures. Accuracy, procedural, and quality control standards are defined for monitoring displacements in hydraulic structures.
Hydraulic and navigation structures require periodic surveys to monitor long-term movements and settlements, or to monitor short-term deflections and deformations. These structures are subject to external loads that cause deformation and permeation of the structure itself, as well as its foundations. Any indication of abnormal behavior may threaten the safety of the structure. Careful monitoring of the loads on a structure and its response to them can aid in determining abnormal behavior of that structure. In general, monitoring consists of both measurements and visual inspections.
 
This seminar, PART TWO will cover satellite (Global Positioning System (GPS)) deformation survey methods used for measuring external movements. Previous seminar PART ONE, covered conventional (terrestrial) methods.
