Field dynamic load testing method for collision resistance and safety of highway corrugated beam barriers

Abstract

The invention discloses a field dynamic load testing method for collision resistance and safety of highway corrugated beam barriers. The method comprises the steps of selecting a collision point; arranging a steel coupling block, a high-speed camera and a displacement measurement scale; colliding a weight against the steel coupling block to obtain measurement results and the like. According to the field dynamic load testing method for collision resistance and safety of highway corrugated beam barriers, safety performances of highway corrugated beam barriers can be tested in the engineering field, and the testing method is not limited by places and highway conditions; and not only the implementation cost is low, but also the testing operation is convenient and rapid, the testing efficiency is high, and testing results are accurate and reliable. The field dynamic load testing method can help highway operation management units grasp security performances of traffic safety facilities of governed highway sections, and can also serve as an approach for quality supervision units to supervise and check barrier construction quality randomly.

Description

technical field

[0001] The invention belongs to the technical field of road traffic, and in particular relates to a method for on-site measurement of the safety performance of a road wave-beam guardrail, which is mainly used for on-site measurement of the safety performance of a road wave-beam guardrail. Background technique

[0002] While my country's highways are promoting the rapid development of the national economy, the high incidence of highway traffic accidents and death rates have also brought many adverse effects to the rapid development of the economy, the continued stability of the society, and the safety of people's lives and properties. The guardrails of highways, especially expressways, are mainly corrugated beam steel guardrails. Many serious traffic accidents have occurred when vehicles smashed through the guardrails and rushed out of the road. Therefore, the safety performance of the guardrail is of great significance to the protection of traffic safety. ...
