Instrumentation & Structural Monitoring of Dams

1. Instrumentation that are used in Structural Monitoring of Dams

2. Overview • Dam Monitoring Instrumentation – The need for it. • The purpose of Dam Monitoring Instrumentation • Dam Monitoring – The Solutions • Dam Monitoring Instrumentation • Dam Monitoring Instrumentation – Concrete Dams

3. Dam Monitoring Instrumentation – The need for it. • Measurement during construction: • Measurement after construction is completed • Measurement for research

4. The purpose of Dam Monitoring Instrumentation Safe operation and functioning of a dam entail monetary advantage and public safety. Dam failure can reason catastrophic harm to lifestyles and property. A properly instrumentation software makes use of the statistics to consider the security of the shape by way of gathering facts and detecting any troubles at a preventable stage. • The purpose includes: • Site investigation • Performance monitoring • Construction control • Design verification • Safety • Legal protection

5. Dam Monitoring – The Solutions As leaders in the geotechnical field, Encardio Rite presents reliable, cost-effective, and complete options for the monitoring of extraordinary kinds of dams. From supply, set up and upkeep to seamless statistics series and far off monitoring, it presents the whole spectrum of services. Here are the solutions/sensors that are provided through Encardio Rite for on-line monitoring: • Different kinds of geotechnical sensors are required for the correct size of a variety of parameters of the dam. • Data Loggers with GSM/GPRS science for computerized monitoring of geotechnical sensors. • LoRa Nodes and Gateway supplied for computerized monitoring. • Automatic Total Stations (ATS) are used for Geodetic Monitoring. • Web Data Management Services with a public cloud that indicators the approved customers and offers the facts online.

6. Dam Monitoring Instrumentation As previously stated, each dam is unique, and no one-size-fits-all solution can be applied to all. It is determined by the dam's size, potential hazards, complexity, foundation, and many other factors known as problems and concerns, as well as the degree of conservatism in the design criteria. Encardio Rite has created a generalised guide for different types of dams based on its involvement with the instrumentation of over 200 dams.

7. Dam Monitoring Instrumentation – Concrete Dams

8. In the table below, we talk about the different instruments required while monitoring Concrete dams along with their purpose and location. Let’s take a look.
