How to distinguish between a hump bridge and bridge bump?
1 Answers
The sign for a hump bridge is a raised arched bridge, used to alert drivers to drive cautiously. It is placed at an appropriate position before a hump bridge with significant curvature that affects sight distance. On the other hand, bridge bump is a sign of uneven road surface, featuring two raised sections rather than an arched bridge. The causes of bridge bump are introduced as follows: 1. Cause 1: The main factors causing bridge bump include uneven settlement, abrupt changes in stiffness, vehicle speed, and the vehicle's own vibration resistance performance. 2. Cause 2: In terms of urban road conditions, it is primarily due to uneven settlement at the junction between flexible roads and rigid structures, resulting in step formation. 3. Cause 3: There are differences in the composition materials, stiffness, strength, and thermal expansion properties between bridges and roadbeds or pavements. Additionally, concentrated stress easily forms at bridge connections when subjected to force.
