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、室內巖石kaiser效應試驗和有限元數值模擬計算研究成果，最大水平主應力方向與隧道洞軸線小角度相交，對隧道圍巖穩定性有利；根據現場應力解除法測試結果，目前鷓鴣山隧道尚未進入高地應力段，最大主應力量級為17mpa 20mpa 。 -
It is stated systematically in the thesis the method ' s theories and measuring principle of all kinds of geostress determination technology. in particular the four methods recommended in 1987 by the committee of test method of the international society of rock mechanics, i. e. two over - coring methods of strain relief in boreholes, hydraulic fracturing method and stress furbish measurement which measures the surface stress
本文較為系統地、全面地介紹了當前國內外通用的各種地應力測量方法的理論、測量原理；特別就國際巖石力學學會試驗方法委員會於1987年推薦的4種地應力測定方法（鉆孔孔徑變形測量法、鉆孔孔壁應變測量法、水壓致裂法以及測量巖體表面應力的應力恢復測量法）作了較為詳細的敘述。 -
