| 摘 要： | 论述了西安地裂缝的空间分布规律和活动特点,并对地裂缝给西安市市政基础设施特别是城市立交带来的灾害进行了系统分析。以长安路立交、互助路立交、绕城高速长安南路立交的现场调查资料为依据,分析了地裂缝对城市立交的破坏模式。认为其结构的主要破坏模式为水平张拉和垂直错动。另外对穿越地裂缝的城市立交的减灾措施以及对拟建工程进行地裂缝专项勘察和采取的结构措施等方面进行了探讨。

| Abstract: | This paper discusses the spatial distribution,activity characters of ground fissure and its destruction to municipal facilities,especially the interchange of Xi＇an city.Based on the site investment data of Chang＇an Road,Huzhu Road,Bypass in South Chang＇an Road,the damage models of interchange by ground fissure is analyzed.The main models are horizontal tension and vertical dislocation.The authors propose reasonable measures to reduce the damage to interchange crossing the ground fissure,including taking special investigation on proposed project,structural measures and so on.Some instances of projects validate the efficiency of the measures.All these are foundation of further study of the technical countermeasures of disaster reduction engineering in the future. |
