茅荆坝隧道工程地质特征及设计方案

The engineering and geological characteristicsof Maojingba tunnel and its design scheme

在对茅荆坝隧道现场地质勘测的基础上 ,介绍了茅荆坝隧道工程地质特征和水文地质条件 ,并对工程设计方案进行了优选 ,提出了隧道施工过程中应加强关键部位的监测和超前地质预报 ,为项目的决策、设计和顺利施工提供依据。

Based on the geological surveying of Maojingba tunnel site,the engineering and geological characteristics and hydrogeological condition of Maojingba tunnel was introduced,and the optimal selection of projectdesign scheme was carried out.It was proposed that the monitoring of key parts and pre geological forecasting should be strengthened,thus providing the reference for the decision making,design and smooth construction of the project.
