摘　　要：大箐隧道位于滇西红层区域,隧道的最大埋深为687m。在施工中克服了滇西红层区域地形、地质、水文特点复杂多变,多涌水(实测最大涌水量高达1800m3/h)、多塌方(大小塌方共计十余次),并针对原结构设计中未考虑外水压力的实际情况,经过结构计算、工程类比,先后提出多种处理方案,最终成功地解决了滇西红层区域隧道施工地形、地质、水文特点复杂多变,多涌水、多塌方等不良地质情况。本文主要介绍了在该隧道施工中处理地下涌水和塌方的施工技术。The DaQing tunnel located at the West-Dian red rock region, tunnel＇s greatest burying depth is 687 meters. Overcame the West-Dian red rock region in the construction, the topograph, the geology, the hydrology characteristic has been complicated and diversified, great water inflows （actual water outflows to reach as high as 1800m^3/h maximum）, more landslides （occurred totally about ten times varied in size）, And aims at the original structural design not to consider that the External water pressure for the actual situation, undergoes structure computation, project analogy, proposed successively many kinds of processing scheme, solved the West-Dian red rock region successfully finally, the topograph of tunnel construction and the geology, the hydrology characteristic have been complicated and diversified, great water inflow, more landslides for the adverse geological situation and so on. This article mainly introduces construction technique which processed underground water inflow and landslide in the tunnel.
