山区输电线路铁塔岩石锚杆基础勘测方法

Study on Rock Bolt Foundation Survey Method of Transmission Line Tower in Mountainous Area

随着岩石锚杆基础在山区特高压输电线路工程中应用的逐步推广,其在工程项目总体经济效益、施工周期、环境保护及安全生产管理等方面已渐显优势。但其对以工程地质调查方法为主的注重于查明场地稳定性为主要任务的传统山区输电线路勘测方法提出了更高要求,即更加重视查明场地地基条件,尤其是场地下伏基岩的坚硬程度和完整程度。本文介绍一种以适合于山区输电线路工程场地的轻便型勘探手段为主、辅以工程地质条件精细化描述和勘测过程控制信息化管理的勘测方法。

With the growing application of rock bolt foundation in high voltage transmission line project in mountainous area, their advantages can be seen in overall economic benefits, short construction period, environmental protection and safety production management and other aspects. But it involves higer requirements for traditional mountainous area transmission line survey which characterized by the engineering geological survey and concentrated on the identification of the stability of the sites. It requires more intense investigation of the site ground conditions, especially for the hardness and the completeness of underlying bedrock under the site. This paper presents a survey method preli minary for a portable means of transmission lines in mountainous area exploration sites, supplemented by the engineering geological conditions refinement description and process control information management, with a view to improve the reliability of rocks bolt foundation site survey in the proposed transmission line tower in the mountainous area.
