公路隧道防排水体系研究现状

Research status of waterproof and drainage system of highway tunnels

对公路隧道防排水体系的应用与研究现状进行了阐述,分析了当前公路隧道防排水系统所存在的缺陷,并分析了缺陷的成因及其防治措施。针对当前公路隧道防排水系统存在的缺陷对隧道结构的危害,从分区防排水和抗冻害防排水设计两个角度出发总结了当前公路隧道的防排水体系的发展趋势。分区防排水理念具有广阔的发展前景,研发抗冻保温新材料、新能源、新的抗冻害排水系统结构形式成为抗冻害防排水设计的发展趋势。

This paper expounds the application and research status of the waterproof and drainage system of highway tunnel,analyses the defects existing in the current waterproof and drainage system of highway tunnel,and analyses the causes of the defects and the preventive measures.In view of the harm of the defects in the current waterproof and drainage system of highway tunnels to the tunnel structure,the development trend of the waterproof and drainage system of highway tunnels is summarized from two aspects of zonal waterproof and drainage and anti-freezing waterproof and drainage design.The concept of zonal waterproofing and drainage has broad prospects for development.Research and development of new antifreezing and heat preservation materials,new energy sources and new structural forms of anti-freezing drainage system have become the development trend of anti-freezing and anti-drainage design.
