【摘要】 以隧道爆破开挖为背景,采用传热学分析方法,将爆破高温视为内热源,构建了围岩在有内热源情况下的二维非稳态导热微分方程,并结合提出的边界条件和初始条件,形成了相应定解问题,通过对二郎山隧道爆破施工的分析,进而得出了一些有益的结论。更多还原

【Abstract】 Taking blasting excavation as background,applying heat transfer analysis method,making blasting high temperature an internal heat source,two-imensional unsteady heat conduction differential equation is forged,combined boundary conditions and initial conditions,solution-decision problem is obtained. Taking Erlang tunnel construction for example,obtained some beneficial conclusions.更多还原
