local dose rate

用法例句

In response to the limitation of conventional index for stability and optimal design of underground rockmass engineering with high geostress and the drawbacks of conventional energy release rate(ERR)rockburst index based on linear elastic theory without brittle failure phenomenon,local energy release rate(LERR),a new rockburst index is proposed.

针对地下工程稳定性分析与优化的常规指标在高地应力条件下的局限性及传统的能量释放率岩爆指标把岩体看成不发生脆性破坏线弹性体的不足,提出局部能量释放率新指标。

Aiming at the insufficient theoretical study on rockburst prevention and the limited evaluation of traditional stress index in the tunneling in deep hard rock,a new method for rockburst prevention measures based on local energy release rate index is proposed.

针对深埋硬岩隧洞围岩脆性破坏分析时传统应力指标的局限性和相应防治措施理论研究不足的特点,在数值分析中应用反映高地应力下硬岩脆性破坏特点的RDM本构模型,结合局部能量释放率评价指标分析硬岩脆性破坏过程中能量释放的强弱,对深埋隧洞开挖过程中防治围岩脆性破坏的设计及施工措施进行综合性研究。
