Method for evaluating construction safety of construction project

Abstract

The invention discloses a method for evaluating the construction safety of a construction project, and the method comprises the steps: determining a personnel scoring index which comprises a pluralityof working parameters of personnel; confirming an equipment scoring index, wherein the equipment scoring index comprises a plurality of physical parameters of equipment; confirming personnel behaviorscoring indexes including a plurality of unsafe behaviors of personnel, the unsafe behaviors being obtained by substituting unsafe behavior data into the planned behavior theoretical model; carryingout multi-layer model construction on the personnel scoring indexes, the equipment scoring indexes and the personnel behavior scoring indexes; obtaining and substituting actual data into the multi-layer model, carrying out Logistic regression analysis on the result of the actual data, and obtaining the weight of each working parameter in the personnel scoring index, the weight of each physical parameter in the equipment scoring index and the weight of each unsafe behavior in the personnel behavior scoring index. According to the evaluation method for the construction safety of the constructionengineering project, the evaluation mode is reasonable, the influence of human factors is reduced, and evaluation standards are unified.

Description

Technical field [0001] The present invention relates to the technical field of engineering construction, and in particular to an evaluation method for the construction safety of a construction project. Background technique [0002] In the field of construction engineering construction in the construction industry, the existing overall project safety assessment method mainly adopts the national standard JGJ59-2011 or an improved safety checklist of the same type as the core content of the inspection, supplemented by experts to conduct on-site inspections and manual inspections The way the project is scored is used to evaluate the overall safety of the project. The evaluation method has the following problems: [0003] 1. The existing inspection content formulated based on the improved national standard JGJ59-2011 lacks generalization and classification from the perspective of safety system science, and only delimits the scoring sub-items from the hazard source itself. Not only is i...

Problems solved by technology

[0003] 1. The existing inspection content formulated based on the improved national standard JGJ59-2011 lacks generalization and classification from the perspective of safety system science. It only delineates the scoring sub-items from the source of danger itself, which is not only scientifically rigorous, but also It does not fully reflect the safety status of the construction site

[0004] 2. The sub-item weights and sub-item score ranges of the existing inspection content are all formed through a certain number of expert demonstrations, which are subject to conditions such as the number of experts, expert ability levels, and expert experience. It is difficult to have a unified standard for the scoring quality and scientificity, and it is impossible to avoid human subjective intervention in scoring

[0005] 3. The scoring methods of the existing evaluation methods rely too much on individual subjective judgments and lack objective constraints

There are a lot of artificial emotional factors in scoring, and it is greatly affected by personal factors such as the ability, experience, and experience of the scorers. The evaluation criteria between different scoring groups are also different. Therefore, this method is not relatively accurate. The safety evaluation results under this method are less referable
