高速公路波形梁护栏改造方案研究

Research on Highway W-Beam Barrier Reconstruct Project

通过有限元模拟方法依托京珠南(广州至太和段)扩建罩面工程研究了原护栏加高方案的防撞性能,提出了3种能满足目前我国评价标准要求的波形梁护栏改造方案,适合应用于目前状况下我国的高速公路波形梁护栏改造及再利用。

To improve the economics of the barrier,this article studies the crashworthiness of the original barrier by FE simulation,relying on the project of expanding and facing construction of Jingzhunan road,then gave three barrier reconstruct projects,all projects can satify the rule of our country and were perfect for highway W-beam barrier reconstruct in our country.
