Risk Assessment of Bridge Construction Safety Based on LEC Method
In order to improve the safety management level during bridge construction,taking the cable hoisting construction of Jinghe Bridge as the background,the risk sources in bridge construction are identified and evaluated to minimize the possibility of accidents.Firstly,through on-site investigation,questionnaire survey,expert consultation,and WBS-RBS method,a risk list for the construction of Jinghe Bridge is established from six aspects:personnel,materials,environment,management,technology,and others.Then,the semi quantitative analysis method(LEC method)is used to evaluate the risk sources of Jinghe Bridge construction.Finally,based on the LEC assessment results,corresponding safety control measures are proposed for major risk sources during the construction process to reduce construction risks,provide suggestions for bridge construction,and ensure the safe and smooth construction of bridges.
