【摘要】 隧道建设和运营中发生的坍塌冒顶、突泥、涌水、开裂、侧移、山体滑坡等地质病害,严重影响到隧道建设质量和运营安全,造成巨大经济损失。地震CT和高密度电法作为隧道病害诊断的有效手段,可用于探测隧道工程与地质病害产生的原因和影响范围,以便提出有效、合理的治理措施。本文结合大风垭隧道地质病害诊断的实例,介绍了这些技术的观测方案、解释原理与诊断分析。更多还原

【Abstract】 The roof fall of tunnel,sudden mud,gushing,cracking,displacement,landslides and other geological disease are often occur in the construction and operation,which seriously affect the construction quality and operational safety of tunnel and result in huge economic losses.The seismic CT and the high-density electrical seismic method,as the effective means for the disease diagnosis of tunnel,could be used to detect the cause and the effect range of tunnel engineering and geological diseases in order to propose effective and reasonable control measures.Combined with the disease diagnosis examples in Dafengya tunnel,the observation program,the explanation theory and diagnosis of these techniques are introduced.更多还原
