摘要
万家寨引黄工程 (一期 )土洞段长达 6 30 1km ,包括Q3、Q2 、N2 土及砂砾石洞段 ,从 1993年开工以来 ,土洞段的防渗止水经过了不断的完善 ,形成了较成熟的方案 ,本文就此方案及其完善过程在查阅了大量的设计与施工资料的基础上 ,作了较为详尽的介绍 ,并从工程地质条件的角度进行了分析 ,在总结经验教训的基础上 ,根据工程实践验提出了一些看法与见解 ,对今后土洞段防渗止水的设计。
The earth runnel of the YRDP is up to 6.301 km long,concerning with the geologic condition of Q 3,Q 2,N 2 and sand and gravel.Since the starting of the YRDP in 1993,the seepage prevention in earth tunnel has been improved progressively,the relatively ripe scheme has been formed.In this paper,the scheme is introduced in detail after consulting quantity of data on design and construction.Some views and opinions are put forward according to the authors'practice by analyzing the engineering geological condition and summarizing the experiences and lessons,which can be as reference for design and construction of the earth tunnel in the future.
