For those of ordinary skill in the art, without creative efforts, other accompanying drawings can be obtained based on these drawings. Among them:

[0044] Figure 1 It is a schematic diagram of the overall structure of a highway construction safety risk assessment method proposed by the present invention. Specific embodiments

[0045] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings of the specification.

[0046] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0047] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0048] Refer to Figure 1 , which is an embodiment of the present invention, providing a highway construction safety risk assessment method. This method includes the following steps:

[0049] Step 1: Data collection. Install environmental sensors at the construction site to collect environmental data of the construction site in real time as the basis for risk assessment. Through the real-time nature of the collected data, the changes in the construction environment can be obtained in real time, and the risks can be quickly evaluated.

[0050] Step 2: Develop an intelligent analysis mechanism for the environmental data of the construction site. Based on the collected environmental data, use intelligent analysis algorithms to predict and judge the possible risks at the construction site and generate a risk report.

[0051] Specifically, the content included in the risk report includes: normalized environmental data, comprehensive environmental risk values, and the impact of predicted risks on the construction plan; the specific intelligent analysis mechanism includes:

[0052] S201: Normalize the risk factor E i (t), and the processing calculation formula is:

[0053]

[0054] Among them, E i (t) represents the real-time data of the i-th environmental factor, and u i represents the reference value of environmental factor i, such as the environmental parameters of common construction standards. Through f i (E i (t)), the normalized risk factor value is obtained, and the logarithmic function is used to smooth the impact of outliers on the whole;

[0055] S202: Combine multiple risk factors to calculate the overall environmental risk value R(t) of the construction site at a certain time t. The comprehensive risk value is calculated by weighted summation, and the calculation formula is:

[0056]

[0057] Among them, w i represents the weight of risk factor i, satisfying N represents that the priority of the construction plan is a positive number, and the higher the value, the more urgent it is.

[0058] S203: Quantify the impact of risk on the construction plan through a dynamic risk attenuation function. The expression of the dynamic risk attenuation function is: e -αR ( t ), where α represents the risk sensitivity adjustment coefficient, and the larger the value, the more significant the impact of risk on the plan.

[0059] If R(t) > the first threshold, it is determined that the risk at the construction site is a high risk, and protective measures are increased to reduce the risk or the construction is postponed; if R(t) < the second threshold, it is determined that the risk at the construction site is a low risk, and the existing construction plan is continued; if the second threshold ≤ R(t) ≤ the first threshold, it is determined that the risk at the construction site is a medium risk, and further monitoring is required and a temporary emergency plan is prepared, and resource investment is increased.

[0060] Through dynamic adjustment, the construction plan can be adjusted at any time according to risk data to ensure construction safety.

[0061] Step 3: Build an optimized construction plan model. Use the information in the risk report as the input of the optimized construction plan model. The optimized construction plan model gives adjustment suggestions again according to the priority of the construction tasks, the number of construction equipment, and the requirements of the construction period, combined with risk data, including: adding manpower, delaying construction, and increasing temporary measures to reduce risk.

[0062] Specifically, the optimized construction plan model combines environmental risk and resource utilization rate, and is defined as follows:

[0063]

[0064] Among them, P opt (t) represents the dynamic priority of the construction plan, T1 and T2 represent the construction time intervals, and G represents the constraint of resource utilization rate on the plan.

[0065] The priority of the construction plan is a positive number. The higher it is, the more urgent it is. The construction in the safety area is arranged first to reduce the construction period delay caused by accidental interruption.

[0066] The expression of the constraint G of the resource utilization rate on the plan is:

[0067]

[0068] Among them, U(t) represents the resource utilization rate, and β represents the resource constraint sensitivity. The larger the value, the greater the impact of the resource limit on the construction plan.

[0069] Reorder the construction plan according to the calculation result of the priority P opt (t), clarify the priority of the urgent tasks, and put forward the following specific adjustment suggestions:

[0070] Add temporary measures. If the priority P opt (t) is greater than the set priority threshold and R(t) > the first threshold, reduce the risk by setting protective measures;

[0071] Delay the construction. If the priority P opt (t) is lower than the set priority threshold and R(t) > the first threshold, stop the construction;

[0072] Dispatch more personnel. If the priority P opt (t) is greater than the set priority threshold and the second threshold ≤ R(t) ≤ the first threshold, mobilize additional resources to complete the task.

[0073] To verify the effectiveness of the present invention, a detailed embodiment is given below, including experimental data and data tables, to verify the effect of the invention scheme in practical applications.

[0074] A certain expressway is under construction, and there are various environmental factor interferences such as wind speed, rainfall, and temperature in the construction area. To improve the construction safety, the present invention scheme is adopted to conduct real-time environmental monitoring, intelligent analysis, and optimize the construction plan for the construction site.

[0075] By collecting the environmental data of the construction site and using the construction safety risk assessment method in the present invention, evaluate the effect of this method in reducing construction accidents and improving construction efficiency.

[0076] Table 1 shows part of the environmental data collected within five days and the risk assessment results generated by intelligent analysis

[0077]

[0078] According to the experimental data, Table 2 is a comparison table of safety and efficiency before and after optimization.

[0079] Time Number of accidents before optimization Number of accidents after optimization Project progress (before optimization) Project progress (after optimization) Day 1 3 1 60％ 75％ Day 2 4 2 62％ 78％ Day 3 2 1 65％ 80％ Day 4 3 1 58％ 74％ Day 5 3 0 59％ 76％

[0080] Combined with the experimental data, it shows that after the construction plan is optimized, the number of accidents at the construction site has decreased significantly. Through the intelligent analysis mechanism, potential high-risk environments can be predicted and prevented, thereby reducing safety accidents caused by environmental factors, and the project progress has also been significantly improved. Through the comprehensive assessment of environmental risks, the construction plan is adjusted, and resources are reasonably allocated, resulting in a project progress improvement of approximately 10% - 15%. Through the implementation of the optimization plan, the construction safety and work efficiency at the construction site have been improved, verifying the effectiveness and practicality of the proposed solution of the present invention in practical applications.
