雪峰山长大隧道涌水量预测讨论摘要: 通过对高速公路雪峰山长大隧道施工中地下水的监测分析,得出雪峰山地下水与基岩裂隙水有着密切的关系,应用正交试验法来分析隧道涌水量与裂隙的各因素的主导关系,从而对隧硐开挖前进行地下水涌水超前预报提供一种新的方法;为隧道施工安全、高效、按质、按量、按期提供准确合理的依据,具有可观的经济效益。关键词: 雪峰山隧道 基岩裂隙水 正交试验 涌水量 预测STUDY ON FORECAST FOR WATER GUSHING CAPACITY IN BIG AND LONG XUEFENGSHAN TUNNEL Huang Dongliang Wu Xiangbin（ Department of geology and environmental engineer, Center South University, Changsha Hunan, China 410083 ）Abstract: By big and long Xuefengshan tunnel of freeway watching、measuring and analyzing groundwater in the construction ,concluding between groundwater of Xuefengshan tunnel and in fracture of bedrock is consanguineous relation. Applying vertical intersection test to analyze water gushing capacity of Xuefengshan tunnel with some factors of fracture are dominant relations, in order that we can use a new method to forecast water gushing capacity of groundwater during constructing tunnel. The same time ,the new method can supply exact and logical basis of safety 、efficiency , on quality、on quantity and on schedule for constructing tunnel. It is provided with considerable economic benefit.Keywords: Xuefengshan tunnel in fracture of bedrock vertical intersection test water gushing capacity forecast前言: 高速公路长大隧道涌水量的预测,目前国内外主要是从宏观上对隧道地下水进行预测,如传统的地下水动力法,柯斯嘉科夫法、大岛洋志法、落合敏郎法;然而对隧硐内局部出现涌水却无能为力。而对岩石裂隙发育的规律性和参数的可量度性,在这方面 D.T .Snow; E.E.Pomm; 杨立中;田开铭等专家学者作过大量的讨论,基于此,针对雪峰山长大隧道局部涌水进行监测,隧址区裂隙水十分发育,故运用数理统计中正交试验法进行分析,得出隧道涌水量与裂隙的各因素的主导关系,从而指导隧道安全、高效施工。1. 工...
