| 摘 要： | 西安地裂缝是在西安断陷构造活动和现代区域引张应力场的作用下，叠加了近期城市过量抽汲深层承压水等非构造因素引起的地表位移变化所致，成为人为因素加速构造地裂活动的典型代表，引起了各级政府以及国内外地学界的普遍关注。地裂缝所经之处，不仅造成地面地下建（构）筑设施严重毁损，而且给城市规划和建设带来了难以估量的经济损失，成为西安市最突出的城市地质灾害。笔者通过阐述西安地裂缝成生地质环境背景及其分布、时空运动规律、发育特征和形成机制，探讨了西安地裂缝勘查工作的思路、技术与方法。

| Abstract: | Formation of ground fracture in Xi'an results form tectonic movement, regional tension field and over-pumping of groundwater. Ground fractures cause severe damages to the buildings and bring difficulties to city planning. As the key city geo-hazard, ground fractures were attached importance by governments of different levels. The paper presents the geological setting, distribution, movement patterns in space and time, development features and formation mechanism of ground fractures in Xi'an. The paper also discusses methodology and techniques of ground fractures exploration. |
