摘要研究目的：近年来，我国的隧道逐渐向大断面、大埋深、大长度方向发展。目前制约隧道发展的主要问题是地质灾害问题。本文主要探讨控制地质灾害的有效措施，以减少复杂地质条件对隧道施工的影响。

研究结论：在长大隧道不断发展的今天，如何有效控制隧道施工地质灾害的发生成为隧道能否顺利通车的关键。本文根据影响隧道施工地质灾害的众多因素，探讨了隧道施工地质灾害的控制措施，认为隧道施工地质灾害控制是一项复杂的工程，需要多方面配合进行；TSP、高密度电阻率等方法为目前比较有效的方法，预警预报需长短结合、上下对照、定性与定量相结合的办法来保证预报的准确性；另外需加强控制爆破、信息化施工以及新技术、新方法应用等方砸的工作。

Abstract：Research purposes: In recent years，the tunnel in China gradually trends to the long one with large section and deep burying．But now the tunnel development is restrained by the geological disasters．This paper mainly discusses the effective measure for control of geological disasters to reduce the impact of the complex geological conditions on tunnel construction．

Research conclusions: In today of the continuous development of tunnel，how to effectively control geological disasters in tunnel construction is the key element for ensuring the normal service of the tunnel．According to the influence factors on the tunnel construction，this paper discusses the measures for control of geological disasters in tunnel construction and points out the control of the geological disasters in tunnel construction is complex engineering and it needs the coordinations among the authorities concerned．The methods of TSP and high density resistivity are the effective ways to control the geological disasters．If the warning forecast is used，combining long—term forecast with short—term forecast，combining the control of the disaster on the upper part with the control of the disaster on lower part and combining the quantitative control with qualitative control are needed to guarantee the the forecast accuracy．In addition，it is necessary to strengthen the works of the blast control，informationalization construction and applications of new technologies and methods．

Key words： long tunnel warning forecast control blast informationalization construction new technology
