Measurement of in - situ stresses by kaiser effect under confining pressures 利用圍壓下巖石的凱澤效應(yīng)測定地應(yīng)力
Obtain these chief research achievements . ( 1 ) the method of hydraulic fracturing , kaiser effect experiment and the finite element numerical simulation computation results , the direction of maximum horizontal principal stress intersect the small - angle of tunnel axial line , it is favorable to the stability of tunnel peripheral rock ; according to the test rust of field stress - relief method , at the present time , zhe gu mount tunnel have n ' t access to high crustal stress site , maximum principal stress magnitude is 17mpa ~ 20mpa 主要獲得以下研究成果: ( 1 )綜合水壓致裂法、室內(nèi)巖石kaiser效應(yīng)試驗和有限元數(shù)值模擬計算研究成果,最大水平主應(yīng)力方向與隧道洞軸線小角度相交,對隧道圍巖穩(wěn)定性有利;根據(jù)現(xiàn)場應(yīng)力解除法測試結(jié)果,目前鷓鴣山隧道尚未進入高地應(yīng)力段,最大主應(yīng)力量級為17mpa 20mpa 。
