| 摘 要： | 地裂缝是西安地区典型的地质灾害,对该地区的各类工程建筑、交通设施、城市生命线工程及土地资源造成威胁,尤其是对拟建的西安地铁二号线的施工与安全运营影响更大。本文首先介绍了西安地裂缝的基本特征,然后阐述了西安地铁二号线穿越地裂缝的基本情况。根据实际观测数据及地表累计活动量确定了地铁二号线穿越的各条地裂缝在不同时间段的活动速率及地裂缝活动的影响范围,在此基础上提出了针对地裂缝灾害的防治措施。

| Abstract: | Ground fissures that are typical geo-hazards in Xi’an area may cause damage of various types of buildings,transportation facilities,city lifeline projects and the land resources,especially endangering the construction and running of Xi’an Subway Line 2.Ground fissures in Xi’an area were introduced firstly,then distribution and characteristics of ground fissures were summarized around Xi’an Subway Line 2.These fissures have been observed and their accumulative moving value were determined.The research results gave the moving speed of each ground fissures at different time stage,and determined the influence scale/area of each fissure.Finally,some suggestions and measures were proposed to prevent and control these ground fissures disasters. |
