水电工程复杂岩石地层跟管钻孔预算定额编制及其应用

Compilation and Application of Budget Quota for Casing Drilling in Complex Rock Stratum of Hydropower Projects

实测定额的编制,是定额观测数据转化为定额成果应用前的分析、处理过程,是保证定额成果质量的重要环节,应采用严谨科学的方法。以金沙江下游某水电站导流洞围堰预留岩硬跟管钻孔实测资料为基础,对水电工程复杂岩石地层跟管钻孔预算定额的编制过程进行实例分析和探讨,所得出的编制方法和编制成果,可供同行参考。

The compilation of the actual measurement quota is the process of analysis and processing before the quota observation data is converted into the quota result,and it is a key step to ensure the quality of the quota result,thus rigorous and scientific methods are required.Based on the measured data of casing drilling in the preserved rock in cofferdam of headrace tunnel of one hydropower station in the lower reaches of Jinsha River,this paper makes an example analysis and discussion on the compilation process of budget quota for casing drilling in complicated rock stratum of hydropower project.Compilation method and result in this paper can be referenced by similar projects.
