摘要
为更好地发挥勘察工作在山区高速公路工程建设过程中的作用,本文以北京兴延高速公路工程建设为例,从工程地质、水文地质角度出发,分别就地形图的精准性、隧道围岩分级的科学性、隧道围岩级别变更、隧道涌水量估算、建设场地周边环境、配合施工等方面,详细总结了兴延高速公路施工过程中遇到的勘察相关问题,分析了相关原因并提出相应勘察工作建议,阐述了全面、细致的勘察工作对保障山区高速公路的顺利建设具有重要意义。
In order to better play the role of investigation in the construction process of mountain expressway engineering,taking the construction of Beijing Xingyan expressway as an example,from the point of view of engineering geology and hydrogeology,in terms of the accuracy of topographic map,the scientific classification of surrounding rock,the change of surrounding rock level,the estimation of water inflow,the surrounding environment of the construction site and the coordination of construction,the investigation related problems encountered during the construction of Xingyan expressway are summarized in detail.The relevant reasons are analyzed and the corresponding investigation suggestion is proposed.The work proposal explains that the comprehensive and meticulous survey work is of great significance to ensure the smooth construction of mountain expressways.
