本文认为西安地裂缝是构造应力活动加强情况下产生的构造裂缝。工程设计应采取以避为主的方针;对于在地裂缝上已经破坏的建筑,可采取结构补强。对于地下管道,一般宜平行地裂缝布置,穿越地裂缝时,宜铺设管沟,地裂缝处需留有沉降缝,管沟内的管子应以柔性结构连结,以防管道断裂。

This paper believes that the Xi’an ground fissures are tectonic fractures that are produced under the condition of strengthening tectonic stress activities. The engineering design should adopt the principle of avoiding the loss; for structures that have been destroyed in the ground fissures, structural reinforcement can be adopted. For underground pipelines, it is generally advisable to arrange parallel ground fissures. When crossing ground fissures, trenches should be laid. Settling seams should be left at the fissures. Pipes in the trenches should be connected by a flexible structure to prevent pipeline rupture.
