| 摘 要： | 陕西三原双槐树地裂缝由两条近平行的地裂缝组成,延伸长度大于4km,地裂缝活动给沿线居民带来了巨大的灾害和经济损失。通过调查访问和探槽、探井、平硐等勘探工程,从平面展布特征、剖面结构特征、活动特征和力学性质等方面描述了该地裂缝的发育特征。结果显示:南侧的F1地裂缝的破碎带宽度和活动程度均大于北侧的F2地裂缝,其中的F1地裂缝破碎带宽度一般大于10m,最大可达50余米,不同期次和不同级次的裂缝数量可达30余条,如此规模的裂缝破碎带宽度和裂缝数量在黄土地区并不多见。

| Abstract: | Huge hazards and economic losses are caused by the ground fissure in Shuanghuaishu Village,Sanyuan County,Shaanxi Province.The ground fissure is consist of two paralleled fissures over 4 km length.Some works of exploratory trench,exploratory well and tunnel are done on site of the fissures.Then the features of plane distribution,section structure,activity and mechanics of the fissures are described in the paper.The exploratory results reveal that the F1 fissure on the south side of Shuanghuaishu ground fissure has larger width of fracture zone and higher active level than the F2 fissure on the North side.There are over 50 m wide areas and over 30 cracks in the fracture zone of the F1 fissure,which is not common in the loess area. |
