A portable brittle fracture monitoring facility

在各种岩土环境和材料中，监测脆性断裂过程非常重要。地面和地下岩土工程的设计和性能可靠性对社会安全和经济具有重要意义。便携式脆性断裂监测设备将利用声发射的特性来帮助我们了解现场和实验室环境中的破坏机制。将在不同的尺度上，包括公路路堑、采石场、露天矿山和大型露天矿坑（深达一公里），监测/描述岩石边坡的不稳定性和相关的脆性断裂/破坏机制。便携式脆性断裂监测仪器系统将用于井下监测矿柱、顶板和底板的性能以及在各种矿山环境下的渐进损伤发展情况。在实验室和实地对材料进行脆性断裂监测的基础研究也将与与自然灾害（滑坡、下沉、火山活动、地震）和资源岩土技术有关的岩石力学研究高度相关。便携式脆性裂缝监测设备将与现有的激光雷达、地面InSAR、摄影测量、调查和地球物理仪器相结合，以形成一个集成的多组分脆性裂缝/岩体表征设施。该系统的结果将用于使用最先进的数字代码约束数值监测，并使用大规模3D图形平台进行可视化/解释

Monitoring brittle fracture processes is important in a wide variety of geotechnical environments and materials. Reliability in the design and performance of rock and soil excavations, both surface and underground, has significant implications for society in terms of safety and economics. A portable brittle fracture monitoring facility will use the characteristics of acoustic emissions to aid in our understanding of failure mechanisms in both field and laboratory environments. The monitoring/characterization of rock slope instability and associated brittle fracture/damage mechanisms will be undertaken at varying scales including highway cuts, quarries, surface mines and large open pits (up to a km in depth). The portable brittle fracture monitoring instrumentation system will be used underground to monitor pillar, roof and floor performance and the development of progressive damage in a range of mine environments. Fundamental studies on the brittle fracture monitoring of materials both in the laboratory and in the field will also be highly relevant to rock mechanics studies associated with natural hazards (landslides, subsidence, vulcanicity, earthquakes) and resource geotechncs. The portable brittle fracture monitoring equipment will be incorporated into existing LiDAR, ground based InSAR, photogrammetry, survey and geophysical instrumentation in order to form an integrated multi-component brittle fracture/rock mass characterization facility. The results of this system will be used to constrain numerical monitoring using state-of-the art numerical codes and visualized/interpreted using a large scale 3D graphics platform
