岩土锚固技术在地质灾害防治工程中的应用

Application of anchoring techniques in geohazard control

针对我国地质灾害发生量大面广的特点，介绍了岩土锚固技术在地灾防治工程施工中的应用技术措施，分析了地灾防治工程施工中遇到的特殊地质环境条件。在对复杂地层进行分析分类的基础上，分析了工程措施对造成地层复杂的影响因素，提出了克服复杂地层钻孔施工难度大应采取的施工工艺方法和技术措施，介绍了选择施工设备及机具的一般原则，对地灾防治工程施工具有一定的指导意义。

This paper mainly introduces application of geotechnical anchoring techniques in geohazard control in China. It analyzes advantages and disadvantages of each kind of techniques in different environmental conditions for the particular soils and rocks. On the other hand, it stresses that drilling techniques are very important during geohazard investigation and implementation of controlling engineering. General principles for selecting construction equipment and drilling tools are also proposed. Finally, the author hopes the article will be a guidance for the geohazard control engineering.
