关于铁路隧道反坡排水费用计算及常见问题的探讨

The calculation of railway tunnel reverse slope drainage cost and Discussion of common problems

随着中国铁路建设事业的发展,山区铁路日益增多,运用隧道工程设计的铁路也日渐广泛。隧道工程遇到溶洞、暗河、软质土、破碎区等复杂地质问题较多,由于隧道工程隐藏地下、地质复杂,采用的施工措施多种多样,而其中反坡排水已渐渐成为一种常见的隧道施工措施。因此,对于隧道反坡排水的投资控制也逐渐成为各参建单位亟待研究的问题。本文通过对当前铁路隧道反坡排水造价管理现状分析,指出费用计算及其过程中常见的问题,提出建议方案,并进行案例分析,对隧道反坡排水的投资控制具有参考意义。

With the development of railway construction in China,the mountain railway is increasing,and the railway using tunnel engineering design is also increasingly extensive.There are many complex geological problems in tunnel engineering,such as karst caves,dark rivers,soft soil and broken areas.Due to the underground hiding and complex geology of tunnel engineering,various construction measures have been adopted,among which reverse slope drainage has gradually become a common tunnel construction measure.Therefore,the investment control of tunnel reverse slope drainage has gradually become an urgent problem to be studied by all participating units.In this paper,through the analysis of the current situation of the railway tunnel reverse slope drainage cost management,points out the cost calculation and the common problems in the process,and puts forward proposals and case analysis,which has reference significance for the investment control of the tunnel reverse slope drainage.
