摘要
冻土具有与一般土质明显不同的物理性质,这也是冻土地区路基病害的主要原因。路基病害主要有路基冻害、下沉及纵向开裂,整治对策主要有修建良好的地表排水系统、设置保温护道、综合治理、换土处理、选择合适的季节进行施工、保护当地原有的植被系统等。
Physical properties of permafrost are obviously different with other soil, and it is also the main causes of roadbed disease.Roadbed disease mainly include subgrade frost damage, subsidence and longitudinal cracking. Improvement countermeasures mainly has built the good surface drainage system, setting up insulation duct, comprehensive control, changing soil treatment, selecting the right season for construction, protecting the original vegetation system, etc.
