隧道结构防排水技术研究

根据设计和有关规范的要求,大部分铁路和公路隧道必须不渗不漏,对隧道及地下工程结构防排水体系设计、性能可靠防排水材料的选择、先进的施工技术和合理的施工工艺的采用和严格的检验和评价体系的建立等几方面的问题进行探讨,并提出一些建议,可有效保证隧道的防排水质量,供设计和施工单位参考。

A Study of the Water-proof and Draining Techniques for Tunnel Structures

According to the requirements prescribed in the design and other relative specifications,most of the railway and highway tunnels have to be made seepage-free,because of which an exploration is made into the design of the waterproof and draining systems for tunnels and other underground structures,the choice of reliable waterproof and draining materials,advanced construction techniques,the rational adoption of construction processes,and the establishment of strict inspection and appraising criteria systems in the paper,with some good suggestions put forward,which may help ensure the waterproof and draining quality of tunnels,as well as serve as a useful reference for other design and construction units.
