摘　　要：随着人们生活水平的提高,对河道工程的完善提出了更高要求,提升寒区透水混凝土铺装使用时间的重要举措就是在防冻胀设计上做到有效性。将实际工程作为对象,利用现场试验方法,分别设定3种找平层材料和基层材料,分析不同方案下寒区河道工程的抗冻胀性能。试验结果显示,河道工程基层与找平层材料可使用透水水稳与中粗砂材料。建议使用相应的工程技术机制,对滞留基层的径流进行及时排空,最大限度弱化冻胀的破坏问题。With the improvement of people s living standards,higher requirements are put forward for the improvement of river engineering.An important measure to extend the service life of permeable concrete pavement in cold regions is to achieve effectiveness in frost heave prevention design.Taking the actual project as the object,using the field test method,three kinds of leveling layer materials and base materials were set up respectively,and the frost heave resistance of river engineering in cold regions under different schemes was analyzed.The test results showed that permeable water-stable and medium-coarse sand materials could be used for the base and leveling layer materials of river engineering.It is suggested to use the corresponding engineering technical mechanism to timely drain the runoff of the retained base,and weaken the damage of frost heave to the greatest extent.
