隧道工程的地质条件复杂多变,为了保证隧道施工安全,有效地防止工程事故、加快施工进度以及保证工程质量,超前地质预报探测就显得十分重要和必要。本文综述了各种超前地质预报方法的优缺点,提出在复杂地质条件下,运用多种方法进行综合预报,并以杭州半山隧道为例,说明综合预报的有效性。
The geological conditions of tunnel engineering are complex and changeable. In order to ensure the safety of tunnel construction, prevent engineering accidents effectively, accelerate the construction progress and ensure the project quality, it is very important and necessary to advance the geological forecasting exploration. In this paper, the advantages and disadvantages of various advanced geological prediction methods are summarized. Based on the complex geological conditions, a comprehensive forecasting method using a variety of methods is proposed. Taking Hangzhou Banshan Tunnel as an example, the effectiveness of comprehensive prediction is demonstrated.
