摘要
该文以某连续高架桥为依托工程,依据该桥梁标准段护栏(包括混凝土箱梁翼缘板桥侧护栏、钢箱梁翼缘板桥侧护栏、混凝土翼缘板中央分隔带护栏和互通匝道护栏)设计参照的碰撞条件和评价标准,采用有限元仿真方法,对依托工程中标准段护栏分别进行结构优化设计,优化后的标准段护栏能够有效地防护失控车辆,降低事故发生的概率,减少事故造成的损失,提高高速公路的交通安全水平。
Relying on a continuous viaduct, and according to the collision conditions and evaluation standards referred for the design of the barriers(including the concrete box beam flange plate barrier at the side of bridge, steel box beam flange plate barrier at the side of bridge, concrete flange plate barrier of the central separator and barrier of interchange ramp) of the standard section of this bridge, the article introduces the structure optimization design of the barriers of the standard section in the project by the finite element simulation method. The barriers of standard section after optimized can efficiently prevent the vehicles out of control, reduce the probability of accidents, decrease the losses caused by the accidents, and improve the traffic safety level of expressways.
