古城西安,古称长安,意即长久平安。 而现在,这座海内外知名的文化古城,却开始遭遇局部地面沉降和地裂缝的困扰。由此已引起了西安市政府有关部门及国内外地学界的高度重视和关注。 11条地裂缝 西安地裂缝是一种很独特的城市地质灾害。50年代末期,当地人在市南郊发现了第一条地裂缝。1976年我国唐山发生大地震后,西安地区的地裂缝活动开始明显加强。特别是80年代中期以后,由于城市缺水,当地人到处开挖深水井,过量抽汲深层承压水,导致出现不均匀地面沉降,由此又拉动了地裂缝的活动加剧。陕西省地质环
Ancient city of Xi’an, Chang’an ancient name, meaning long-term peace. Now, this well-known cultural city at home and abroad, but it has begun to experience the problems of local land subsidence and ground fissures. Which has caused the Xi’an Municipal Government departments and domestic and foreign scholars pay close attention and attention. 11 ground fissures Xi’an fissure is a very unique urban geological disaster. In the late 1950s, locals found the first crack in the southern suburbs of the city. After the great earthquake in Tangshan of China in 1976, the ground fissure activity in Xi’an began to noticeably strengthen. Especially since the mid-1980s, due to the lack of water in cities, local people were digging deep water wells everywhere and pumping excessively deep confined water, resulting in uneven ground subsidence, which in turn caused the activity of ground fissures to intensify.
