基于电阻率成像的灌浆工程对穿黄隧道的渗漏影响分析

Analysis of the Impact of Grouting Engineering on Leakage of theYellow River-Crossing Tunnel Based on Electrical Resistivity Tomography

摘要:

穿黄隧道工程下穿黄河大堤时会降低堤防土层的强度,引发堤身开裂,危及堤防正常运行,灌浆技术可有效地解决隧道周围坝体因施工扰动诱发的渗漏隐患。基于电阻率成像技术可对穿黄隧道引起渗漏隐患处理进行检测,通过切片处理直观反演了灌浆处理结果,可为采取针对性坝体隐患处理措施提供依据。

Abstract:

When the Yellow River-Crossing Tunnel project passes under the Yellow River dyke, it will reduce thestrength of the dyke soil layer, cause cracks in the dyke body, and endanger the normal operation of the dyke. Groutinglechnology can effectively solve the leakage induced by construction disturbance around the lunnel.Based on electricalresistivity lomography (ER'T) technology, the reatment of leakage caused by the Yellow River-Crossing Tunnel can bedetected. The grouting treatment results are intuitively inverted through slice processing, which can provide a basis forformulating targeted measures to address dyke hidden dangers.
