Description

technical field [0001] The present invention relates to an in-situ test and measurement system for buried pipelines across faults, and more specifically relates to a test measurement and loading control system for fault response of buried pipelines at the in-situ test site, mainly used for observation and Monitoring the process and response of in-situ testing of buried pipelines across faults. Background technique [0002] Buried pipelines occupy an important position in modern production and life, and are important urban lifeline projects. The buried pipeline system is a typical line and network project, which inevitably needs to cross some unfavorable or dangerous areas for earthquake resistance. Crossing faults is one of the key engineering problems that buried pipelines have to face and need to solve. The mechanical performance and failure mechanism of buried pipelines across faults require reliable and accurate actual failure data as the research basis. The most reliab...

AI Technical Summary

Problems solved by technology

Model tests inevitably bring about problems such as size effects and boundary condition errors, and cannot well reflect the fault response characteristics of buried pipelines across faults

The in-situ test can better overcome the shortcomings of the model test, but it is difficult to implement and control the fault loading in the in-situ site, and there are certain difficulties in the underground observation and data collection of the fault response of the pipeline
