【摘要】 长安地裂缝是新近发现的地裂缝,分布在临潼—长安断裂带南盘。总体为北东走向,活动方式为南倾南降,与分布于临潼—长安断裂带北盘的西安地裂缝有相似的构造条件,但与西安地裂缝活动性有较大差异,该地裂缝活动性较弱,自晚更新世以来的地质历史时期中,未见明显活动,处于隐伏状态。文章对长安地裂缝的基本特征和成因进行了分析,对地裂缝场地勘察与工程设计进行了探讨。更多还原

【Abstract】 Chang’an ground fissure is a newly discovered ground fissure,located in south block of Lintong-Chang’an fracture.This new ground fissure’s overall direction strike the north-east direction and the mode of its movement is south block’s falling down.Chang’an ground fissure has similar constructions as Xi’an ground fissure,which located in north block of Lintong-Chang’an fracture,but the new ground fissure is quite different from Xi’an ground fissure on character of the movement,it’s weaker.Since the late Pleistocene period’s geological history,Chang’an ground fissure has no significant activity and is right in a hidden state.In this paper,the author analyzed the basic characteristics of Chang’an ground fissure and formation causes,and discussed the ground fissure site investigation and engineering design.更多还原
