摘要

以新大巴山隧道溶洞处理为例，根据溶洞的发育特点,简要介绍岩溶的处理方案及桩基加固的施工工艺，从大管棚超前支护，小导管径向注浆，钢管桩及旋喷桩处理等几个方面对大型充填型溶洞处理技术进行探讨，希望能给类似工程处理提供参考。

Abstract

Taking the treatment of the karst caves encountered during the construction of new Dabashan tunnel as an example, the authors briefly present the treatment scheme for karst caves and the reinforcement method for pile tundations. The authors make further discussion on the treatment technology for large scale fillingtype karst caves in terms of advance reinforcement by large pipe roof, radial grouting through small pipes, steel pipe pile and jet grouting pile. This paper can provide reference for similar projects in the future.

Key words： tunnel ; fillingtype karst cave ; large pipe roof ; CRD method steel pipe pile ; jet grouting pile
