Necessity and reliability of pre-monitoring network for energy pipeline

In concerned with high risk of geological hazard and requirements of pipeline integrity management in china, this paper focuses on the monitoring data to the change of the stress and strain of pipe body to establish earlier monitoring warning system of geological hazard .This system can find the precursor of disaster accurately with a small amount of monitoring costs and improve the relevance of disaster prevention and reduce the cost of comprehensive management of pipeline. Based on above method, a project was conducted to prove reliability and necessity of this pre-monitoring network.
