Development and application of a rockburst database management system

  • 摘要: 針對深部巖體工程科學前沿的巖爆研究難題,分析了制約其動態定量及智能化預警研究的挑戰性問題。為突破挑戰問題制約,采用面向對象的B/S+C/S結構,建立了巖爆數據庫管理系統,包含巖爆案例數據庫、微震波形數據庫、微震時序數據庫,具備多工程管理、詳細數據采集、查詢分析、結果導出等功能的巖爆數據庫管理系統,成功實現了多工程、多源巖爆災害信息的詳細采集與有效管理。利用多個具有巖爆災害的深埋巖體工程,對巖爆數據庫管理系統進行了應用,取得了較好的效果。結果表明建立的巖爆數據庫管理系統具有較好的適用性,可為不同工程巖爆類比研究、巖爆智能預警研究等提供科學、可靠的數據基礎與參考。

     

    Abstract: Aiming at the research problems on rockbursts in the forefront of deep rock mass engineering science, the challenges restricting its quantitative dynamics and intelligent warning research were analyzed. The development mechanism of rockbursts and rockburst intelligent monitoring and warning are the key technical issues for the safe construction of deep rock mass engineering. In this study, a rockburst database management system was established to accurately and effectively collect the characteristics of rockbursts and their corresponding geological as well as excavation information, fracture response monitoring, and other information in different stages of the project. On this basis, the differences and connections between different projects were constructed to study the rockburst mechanism and intelligent monitoring and warning of rockbursts as a whole. Accordingly, the problems of lack of sample numbers and unbalanced sample structure of rockburst cases of different types and intensities were effectively solved. Object-oriented B/S + C/S structure was adopted, and the rockburst database management system was established to break through the constraints of challenges. This rockburst database management system includes a rockburst case database, microseismic waveform database, and microseismic time sequence database and has the functions of multi-engineering management, detailed data acquisition, query analysis, and result export. The detailed collection and effective management of multi-engineering and multi-source rockburst disaster information were successfully realized using the database management system. Several deep-buried rock mass projects with the rockburst disaster were used to apply the rockburst database management system. The three challenges of the rockburst mechanism and rockburst intelligent monitoring as well as warning were verified by examples, and satisfactory results were obtained. The results show that the rockburst database management system established in this study has good applicability, can be adapted to the needs of different stages of the project, and can also provide scientific and reliable data basis and reference for rockburst analogy and intelligent warning research in different projects.
