在研究過程中本文主要做了以下工作: ( 1 )針對巖石損傷變化較小時,運用ct均值和方差分析不方便的缺陷,本文提出運用對ct數范圍劃分區段的方法,根據各區段統計頻率的變化規律來分析損傷擴展狀況; ( 2 )針對巖石受到外部作用的多變性,本文提出了基準損傷,正損傷,負損傷的概念,在某種程度上考慮了巖石受到外部作用時的壓密情況; ( 3 )現有的基於ct數的損傷變量大多需要用到巖石基體的ct均值,這實際上是很難觀測到的,因此本文建議了一個可運用巖石初始狀態ct均值的損傷變量,由於現有的勒邁特教授應變等價原理使用上的不便,本文在其基礎上進行了推廣; ( 4 )建議了一個可用巖石初始狀態ct數和彈性模量的單軸損傷本構方程,並用算例進行了驗證; ( 5 )對兩種不同巖石在開放環境下受到凍融循環作用且融化過程中補水時,內部損傷隨凍融循環次數增加的擴展規律進行了探討,主要運用了常規的ct均值和ct方差的分析方法進行分析,試驗發現:對于孔隙率和含水率較高,密度和強度較低的軟弱巖石,凍融循環次數對損傷結構的擴展有明顯的影響,而對于孔隙率和含水率較低,密度和強度較高的硬巖,凍融循環次數對其損傷結構擴展初期由於含水率低的原因,影響不是太大,而後期由於水補給后,含水率較高的原因,凍融影響逐漸增大; ( 6 )運用了本文提出的區段劃分和統計頻率的方法,深入地分析了開放環境下的線性溫度變化的凍融循環次數,凍結溫度,凍結速度不同巖石作用時,其內部損傷隨凍融循環次數,凍結速度和凍結溫度變化的擴展規律,需要指出的是除了在試驗前飽水外,凍融過程中沒有補水。分享友人
