摘要
红层砂泥岩区深埋特长隧道数量日益增多,由于隧道长度较大,往往跨越多个不同的水文单元,涌水量关系着施工开挖与后期营运安全,因此,红层砂泥岩深埋特长隧道的最大涌水量分析是隧道勘察中的关键问题。本文以云南某拟建特长隧道为研究对象,对其进行水文地质专题研究,通过抽水试验得到其岩层渗透系数,进行水文地质单元分区后采用不同计算方法综合预测分析其涌水量,为类似红层砂泥岩深埋特长隧道的涌水量综合预测分析提供参考。
The number of deep buried extra-long tunnels in the red sandstone and mudstone region is increasing.Due to the large length of the tunnel,it often spans multiple different hydrological units,and the water inflow is related to the construction,excavation,and later operation safety.Therefore,the analysis of the maximum water inflow of deep buried extra-long tunnels in the red sandstone and mudstone is a key issue in tunnel exploration.This article takes a proposed extra-long tunnel in Yunnan as the research object,conducts a hydrogeological thematic study on it,obtains its rock permeability coefficient through pumping tests,conducts hydrogeological unit zoning,and uses different calculation methods to comprehensively predict and analyze its water inflow,providing a reference for the comprehensive prediction and analysis of water inflow of similar red bed sand mudstone deep buried extra-long tunnels.
