摘要
贵新隧道是福州西北段绕城高速公路的控制性工程,属硬质岩区深埋长大隧道,地应力及岩爆问题是隧道设计施工必须考虑的重要问题,本文通过深孔水压致裂法进行实地地应力测量及回归分析,为隧道设计提供地应力参数及岩爆评价。
GuiXing tunnel is control project of the northwest expressway of FuZhou. it is a deep,long and hard rock zone tonnel, in--situ stress and rock burst problem are important issues that the tunnel design and construction must be considered. This paper through the deep hole hydraulic fracturing stress measurement and regression analysis, provide design parameters of in--situ stress and rock burst for tunnel design.
