摘要：Mountain tunnel crossing a normal fault in seismically active zone is easily affected by normal fault slip and earthquake. It is necessary to study tunnel dynamic response under action of normal fault slip and earthquake. In this paper, a three-dimensional normal fault sliding device was designed, and a shaking table test was carried out to study tunnel seismic performance under normal fault slip. The results show that peak acceleration of lining is dominated by an existence of fault and direction of seismic excitation, not normal fault slip. And the incremental strains of lining in critical zone with 1.7 times fault thickness and centered in faults induced by normal fault slip and seismic excitation are larger than ones only by seismic excitation. And the incremental strains in critical zone increase with the increase of normal fault slip magnitude ranging from 0 to 2 mm. And normal fault slip results in a significant reduction of overall tunnel stiffness subjected to an earthquake. These experimental results provide a scientific reference for prevention and control measurement of tunnel damage under earthquake and normal fault slip.

摘要：基于"投资-效益"准则,建立SRC框架结构的优化数学模型,优化目标包括初始造价及结构失效损失期望最小化两部分。利用加权系数调整两者重要程度。为获得结构失效损失期望值计算结构失效概率;为获得接近实际的失效概率,对SRC框架结构进行模糊可靠度分析,主要内容包括:确定SRC框架结构抗震目标性能水平量化值,建立结构模糊功能函数,提出考虑模糊性Monte Carlo法。将SRC框架结构优化过程调整为含内外两层的迭代过程,外层对优化模型进行计算,内层对结构进行模糊可靠度分析。考虑优化模型中设计变量、约束条件过多、目标函数非线性程度较高等特点,提出适用于SRC框架结构的分阶段优化计算方法。通过对一榀单跨三层SRC框架结构优化设计,表明所提优化方法可获得理想、可靠的设计效果。
