Abstract
Basing on highway bridge construction technique and management features, this paper conducts analysis and establishment to construction safety risk factor, index system, etc. of actual engineering, after using vague synthetic judgment method, analytic hierarchy process, implement research via integrated evaluation method, makes out argument to different safety risk factors, establishes bridge safety risk factor collection via method of comprehensive assessment, confirms bridge safety risk incidence value, judges matrix by using MATLAB construction vagueness, finally calculates concrete risk gradation sort, and gets highway bridge construction safety risk grade. Through practice it has proved that the construction safety risk assessment method is based on the method of quantification, can find out biggest influence factors on the safety of Bridges in engineering, and can also reduce the misjudgment caused by subjective factors. The safety of the bridge has a positive practical significance.
Highlights
The safety of the bridge is a kind of ability that can still work normally under the load without causing accidents
Basing on highway bridge construction technique and management features, this paper conducts analysis and establishment to construction safety risk factor, index system, etc. of actual engineering, after using vague synthetic judgment method, analytic hierarchy process, implement research via integrated evaluation method, makes out argument to different safety risk factors, establishes bridge safety risk factor collection via method of comprehensive assessment, confirms bridge safety risk incidence value, judges matrix by using MATLAB construction vagueness, calculates concrete risk gradation sort, and gets highway bridge construction safety risk grade
1) This paper finds out safety factors that affect bridge engineering combining reality and conduct systematic category to it, conducts category according to external factor, materials technology factor, construction supervision factor, technical factor, supervision maintenance factor and establishes bridge construction safety risk factor evaluation index system
Summary
The safety of the bridge is a kind of ability that can still work normally under the load without causing accidents. There are many influencing factors for this ability Speaking, it involves the design of the bridge structure, material selection, and construction technology. It involves the design of the bridge structure, material selection, and construction technology It is affected by the degree of maintenance, maintenance, and use after completion. The assessment of the safety of bridges is a means to determine that the current bridges. During the construction of actual roads and bridges, all parties involved have unique security risks. If these problems are not adequately prevented, they will likely lead to casualties. Through the construction of the evaluation model, specific construction safety risk factors can be identified and calculated, and specific safety can be determined according to its importance. The risk level provides important data for the following risk control
