첫댓글 3. To = P1 - P2에서 , 25-20 = 5Mpa
1번은 저것 만으로 절대 풀수 없으니 넘어가시길.. 2번은 응용지구물리학(초록색책) 참고하시기 바랍니다. 3번은 위에분설명이 맞아요
3번... 첫번째 피크는 처음 절리가 열리면서 생기는 최고압력이고, 절리가 열리면서 주입압력이 감소합니다. 두번째 피크는 처음 열린 절리가 파쇄되는 최고압력이며, 파쇄된 절리를 통해 압력이 다시 낮아집니다. 따라서 처음 절리를 여는 최고압력에서 이 절리를 파쇄시키는 최고압력을 빼면, 암반의 인장강도를 구할 수 있습니다. 5Mpa이 맞습니다.
수압파쇄실험법 이부경의 암석역학 p439 참고하세요 ㅋㅋ 식이 길어서 ...
좋은 답변 감사합니다..... ^^
