汶川地震震中区高速公路隧道超前地质预报方法

摘要

Yingxiu -Wenchuan expressway is located in Wenchuan earthquake epicenter which has complex geological conditions, such as developed cracks, loose and fractured rocks, abundant groundwater and accumulation of rock masses due to the earthquake. This paper discusses the geological prediction scheme for the tunnel based on the analysis of domestic and international geological prediction methods, and illustrates the application and effects.%映汶高速公路公路位于四川汶川大地震震中,受地震强烈构造作用影响,隧址区岩体裂隙发育,松散破碎,存在构造富水,地震垮塌堆积体众多,地质条件极为复杂.文章根据本工程隧道的工程地质问题,通过对国内外隧道超前地质预报常用方法的分析,提出了针对本工程的隧道超前地质预报方案,并对地质预报的实施应用及效果进行了举例说明.
