Abstract
Active fault creep slip induces deformation of rock mass buried deeply in fault zones that significantly affect the operational safety of long linear projects passing through it. Displacement distribution patterns of rock masses in active fault zones which have been investigated previously are the key design basis for such projects. Therefore, a discrete element numerical model with different fault types, slip time, dip angles, and complex geological features was established, and then the creep slip for normal, reverse, and strike-slip faults were simulated to analyze the displacement distribution in the fault rock mass. A disk rotation test system and the corresponding laboratory test method were developed for simulating rock mass displacement induced by creep slippage of faults. A series of rotation tests for soft-and hard-layered specimens under combined compression and torsional stress were conducted to verify the numerical results and analyze the factors influencing the displacement distribution. An S-shaped displacement distribution independent of fault dip angle was identified corresponding to reverse, normal, and strike-slip faults. The results indicated that the higher the degree of horizontal extrusion, the softer the rock mass at the fault core, and the higher the degree of displacement concentration in the fault core; about 70% of the creep slip displacement occurs within this zone under 100 years of creep slippage.
摘要
活断层的蠕滑错动对穿越其中的隧洞(道)、管线等长线工程的运行安全影响巨大, 工程沿线活 断层蠕滑位移分布模式是此类工程建筑物的重要设计依据。基于断层带的活动特征、地质条件以及各 区域内的岩体性质, 采用离散元方法建立了不同类型和倾角的断层数值模型。将活断层的蠕滑错动相 似比拟为地质分层间的持续性剪切, 研制并采用了圆盘旋转试验装置对“软硬”分层试样进行了压扭应 力组合下的旋转试验。基于数值模拟与试验结果, 提出了正断层、逆断层及走滑断层的位移分布模式。 结果表明, 逆断层、正断层和走滑断层的错动位移均呈S 型, 位移模式与断层倾角无相关性; 错动 位移在断层破碎带内的分布规律具有非线性特征, 水平挤压程度越高, 该区域内的位移集中程度越高; 百年蠕滑错动下约70%的错动位移产生在断层核内。
