摘要
HLJ水电站引水渠0+500~1+266段地质条件从上到下依次为洪积碎石土层,洪积粉质黏土层,冲积粉土~粉砂层,该段土质具有冻胀性和湿陷性,为解决该段渠道冻胀性及湿陷性提出了多个可行性方案进行比较,最后确定一个经济合理的方案。同时为了保证渠道边坡衬砌及基础的稳定,拟定2个方案进行比较,确定经济合理的边坡。比选结果对于类似工程地质渠道有重要的参考价值和指导意义。
The geological conditions of 0＋500 ~1＋266 secti o n of HLJ hydropower station diversion channel, from top to bottom was diluvial macadam soil layers, diluvial silty clay layer, alluvial silt to silty sand. The soil with frost heave and collapsibility, in order to solve the frost heaving and collapsibility, this paper put forward a feasible scheme comparison,finally determine a reasonable scheme. At the same time, in order to ensure the stability of the lining and foundation of the channel slope, two schemes are compared to determine the economic and reasonable slope. The comparison results have important reference value and guiding significance for similar engineering geological channel.
