为了保证清平隧道进口的施工安全和进度,应用TSP超前预报仪对清平隧道左右两洞前方110m范围内地质条件及异常进行了预测,再根据地质探测探测数据图像,进一步结合地勘资料及掌子面围岩地质揭示情况进行解译,研究结果表明,渝广高速公路清平隧道进口处岩体质量较差,存在多处节理构造带,带内含地下水,施工中存在涌水、掉块和塌方等安全隐患,施工中应及时采取相应的对策。 In order to ensure the construction safety and progress of the Qingping tunnel entrance, the TSP advance forecaster is used to predict the geological conditions and anomalies within 110m in front of the two left and right tunnels of the Qingping tunnel. Based on the geological exploration and detection data and images, The results show that the quality of rock masses at the entrance of Qingping tunnel of Chongqing-Guangrao Expressway is poor, there are many syndectonic belts with groundwater in the belts, water gushing, falling blocks and landslides in the construction Safety hazard, the construction should promptly take appropriate countermeasures.
