摘要
高速公路寿命期内会进行多次罩面,导致波形梁护栏与路面相对高度不足,因此其实际防护能力远低于设计标准,对道路运行产生了极大的隐患。在总结了现有波形梁护栏养护及改造措施后,提出了高度可调节的新型护栏,使护栏与路面相对高度始终维持在规范要求的最佳高度,从而使波形梁护栏在公路寿命期内满足其使用要求。
Since highway would experience several times of covering of pavement during its service life which would lead to insufficiency of relative height between wave- beam barriers and pavement,the actual protective capability of the barries is way lower than design standard that left great potential safety hazard on the road traffic.After summarizing the maintenance and remoulding measurements of existing wave- beam barriers,a new type barrier with adjustable height was proposed which may keep the relative height between wave- beam barriers and pavement continuously at its optimum as per specification so that the wave- beam barriers can meet the operating requirements in highway service life.
