摘    要:地震时发震断层错动可能导致基岩上覆土层破裂,致使断层上的工程结构破坏,特别是地下工程结构,这一问题的研究受到人们的特别关注.对以往的研究成果进行了分析,总结了上覆土层的破裂规律,讨论了研究中存在的问题及研究发展的趋势.已有研究结果表明,断层的运动形式、错动位移量、错动方向及上覆土层的厚度与物理性质等是影响土层破裂的主要因素,而且各类断层中逆断层运动对土层造成的破坏最严重,其次是正断层,走滑断层的破坏相对较轻.

关 键 词:地震作用  断层错动  地下结构

Abstract:The rupture of soil layer on bedrock may be induced by earthquake fault dislocation of bedrock when earthquake occurs, and it will directly lead to destruction of engineering structures upon the fault, especially the underground structures. The study on this problem has been attracting more attention in recent years. Previous research results and progresses in the field have been analysed, and the rupture modes have been summarized. Some existing problems and research tendencies are analyzed. Some research ...
Keywords:earthquake effects  faulting  underground structures
