摘要
受溶蚀作用、构造作用影响,渝东南部岩溶山区槽谷内分布有大量岩溶洼地,洼地内地表入渗量极大,强降雨后,地表水大量汇集下渗,极易造成雨季隧道发生大规模突涌水。为此,依托彭水隧道,结合右洞YK156+320处实际突涌水情况,具体分析了本次突涌水地质灾害原因,提出了处治原则及相应的处治关键技术,取得较为理想的效果,对类似工程设计、施工颇具参考价值。
Due to the influence of dissolution and tectonic processes,there are a large number of karst depressions distributed in the valleys of karst mountainous areas in southeastern Chongqing.The surface infiltration in these depressions is extremely high.After heavy rainfall,a large amount of surface water accumulates and seeps down,easily causing large-scale sudden water inrush in tunnels during the rainy season.Therefore,based on the Pengshui Tunnel and the actual water inrush situation at YK156+320 in the right tunnel,the causes of this geological disaster were analyzed in detail,and treatment principles and corresponding key technologies were proposed,achieving ideal results.This has reference value for similar engineering design and construction.
