fenner 中文意思是什麼
fenner
解釋
芬納-
Based on the idea of the measured displacement can be divided into elastic and plastic parts, elastic parameters can back analyzed by the elastic displacement, which is the measured instant after blasting excavation. the strength parameter can be got by plastic deformation, which is the measured during the period of construction loop without blasting excavation. lastly, depending on fenner formula, a new and valid evaluating criterion for tunnel stability is presented and the effect of deformation modulus, cohesion, internal friction angle and overburden can be considered
以解析理論為基礎提出一種實用而簡便的圓形洞室彈性反分析方法，且將其應用推廣到其它洞型、分步位移等不同情況；提出一種圍巖強度參數反演方法，並對其可靠性進行了初步研究； （ 4 ）依據芬納公式提出了能夠考慮圍巖變形模量、強度參數、埋深等主要因素的、新的、有效的圍巖穩定性評判方法。
