摘要:

介绍采用小直径开敞式TBM进行超前平导施工的意义、目的和国外采用小直径TBM进行超前导洞施工的实例;分析国内采用小直径开敞式TBM进行超前导洞施工的可行性;总结进行超前导洞施工时选择开敞式TBM的考虑因素。得出以下结论:利用小直径开敞式TBM进行长大隧道超前导洞施工,符合国家对基本建设的环保和安全的要求;当前的综合国力和施工技术水平也具备了相应的条件;选择小直径TBM时应考虑其特点,并满足“快速掘进、探明地质、支持正洞”的要求。

Abstract:

The significance and targets of pilot tunnels constructed by smalldiameter open TBMs are presented, cases of pilot tunnels constructed by smalldiameter open TBMs abroad are listed, the feasibility to build pilot tunnels by smalldiameter open TBMs is analyzed and factors to be considered in the selection of smalldiameter open TBMs in the construction of pilot tunnels are summarized. Conclusions drawn are as follows: 1) The concept to build pilot tunnels by smalldiameter open TBMs meets the requirements of the state for the infrastructure construction in terms of environment protection and safety; 2) The comprehensive national capability and the construction technologies have reached the relevant requirements; 3) The features of smalldiameter open TBMs should be taken into full consideration and the requirements of rapid boring, geology probing and assistance to the main tunnel construction should be satisfied.

Key words: parallel pilot construction, smalldiameter open TBM, long tunnel with large crosssection, advance pilot tunnel
