摘要
在隧道施工中不可避免地会遇到岩溶问题。为解决隧道穿越溶洞所遇到的技术难题,保证安全有效地进行隧道建设,需要对岩溶区隧道围岩进行探测和研究。本文以典型施工现场为依托,根据具体溶洞的特点,提出了长孔超前钻探、精确测量及水文地质分析等隧道岩溶处置技术,有效地保证了现场溶洞的安全处置和隧道的安全施工,也为以后的研究工作提供一定的参考价值。
It is inevitable to encounter karst problems during tunnel construction.To solve the technical difficulties encountered during tunnelling through karst caves and ensure safe and effective tunnel construction,it is necessary to detect and study the surrounding rock of tunnels in karst areas.This paper puts forward tunnel cave treatment technologies such as long hole advanced drilling,accurate measurement,hydrogeology analysis based on typical construction sites and the characteristics of specific karst caves,which effectively ensure the safe treatment of karst caves and tunnel construction and can also provide certain reference value for future research.
