[0002] With the increase in the number of tunnels and motor vehicles in my country, and the existence of irregular driving conditions due to the structure of the tunnel itself and the owners of motor vehicles, the number of fires has been increasing year by year. Existing personnel often use numerical simulation to study the fire characteristics and evacuation rules of highway tunnels. Among them, FDS (Fire Dynamics Simulator) software or Pyrosim software based on FDS secondary development is often used in highway tunnel fire simulation, and FDS or Pathfinder software is often used in highway tunnel evacuation simulation.

Generally, the length direction is the X-axis direction, the width direction is the Y-axis direction, and the height direction is the Z-axis direction. Then the X starting coordinate of the highway tunnel is X start Indicates and ends coordinates with X end The length of the highway tunnel is represented by |X end -X start | indicates; the Z coordinate of the tunnel road surface is represented by Z0, and the tunnel includes l lanes, 1≤l≤5, and the center line of each lane needs to be set with a Y coordinate, such as Y1, Y2...Y j ...Y n-1 , Y n In a specific embodiment, Figure 3 As shown, the number of lanes can be set to 3, and the vehicle spacing between lanes is 5.0m. The simulation length is 1000m, and the Y coordinates of the center lines of the lanes are 3.5, 7.0, and 10.5 respectively. For the vehicle spacing, the value of 3-10m can be considered in congestion, and the value of 50-60m can be considered in unblocked conditions. Other situations can be considered as appropriate.

[0062] At the same time, the parameters of each lane need to be set, including the average vehicle distance VS k and the proportion of different vehicle types in the corresponding lanes R(R VTi , VL k ), and at the same time, the proportion of each vehicle type in the corresponding lane R (R VTi , VLk ) must satisfy the following formula:

[0063]

[0064] In actual embodiments, the embodiments can generally be set as follows: the distribution ratios of different lanes for passenger cars are 0.6, 0.3, and 0.1; the distribution ratios of different lanes for large buses are 0.3, 0.5, and 0.2; the distribution ratios of different lanes for minibuses are 0.2, 0.6, and 0.2; the distribution ratios of different lanes for small trucks are 0.1, 0.4, and 0.5; the distribution ratios of different lanes for large trucks are 0.1, 0.2, and 0.7. The corresponding settings can also be adjusted according to actual needs.

[0065] After completing the above parameter settings, you can perform the following steps:

[0066] S20, according to the highway tunnel space parameters, parameters of each vehicle type, and lane parameters, a ratio of the number of corresponding vehicle types in corresponding lanes to the total number of all vehicle types is obtained.

[0067] Specifically, according to the proportion of different vehicle types in the corresponding lanes R(R VTi , VL k ) and the proportion of each model R VTi Get the ratio of the number of corresponding models in the corresponding lane to the total number of all models R (R VTi , VL k , TVN), the specific formula is as follows:

[0068]

[0069] S30, obtaining the number of vehicles in the corresponding lane according to the spatial parameters of the highway tunnel, the parameters of each vehicle type, and the ratio of the number of the corresponding vehicle type in the corresponding lane to the total number of all vehicle types;

[0070] Specifically, according to the length of the tunnel |X end -X start |、Average distance between vehicles in each lane VS k , the ratio of the number of each model in the corresponding lane to the total number of all models R (R VTi , VL k , TVN), vehicle length L VTi Get the number of vehicles VN in the corresponding lane k , the specific formula is as follows:

[0071]

[0072] Furthermore, the number of vehicles VN in each lane can be k Get the total number of all models TVN. The specific formula is as follows: TVN = VN1 + VN2... + VNl-1 +VN l .

[0073] And executing step S40, the number of the corresponding model in the corresponding lane is obtained according to the ratio of the number of vehicles in each lane to the number of the corresponding model in the corresponding lane to the total number of all models. Specifically, according to the number of vehicles in each lane VN k The proportion of each vehicle type in the corresponding lane R(R VTi , VL k , TVN), and get the number of corresponding models in the corresponding lanes VN k (VT i ), the specific formula is as follows:

[0074]

[0075] Furthermore, after step S40, the method further includes:

[0076] According to the number of lanes VN of each vehicle type k (VT i ) and the number of people on the vehicle model P VTi Get the number of people load TP (R) of the corresponding vehicle type in the corresponding lane VTi , VL k ), the specific formula is as follows:

[0077] TP(R VTi , VL k )=VN k (VT i )×P VTi ;

[0078] Furthermore, according to the number of passengers TP (R VTi , VL k ) to obtain the total number of passenger loads TP (VL) of all vehicle types in the corresponding lanes k ), the specific formula is: TP(VL k )=TP(R VT1 , VL k )+TP(R VT2 , VL k )...+TP(R VTm-1 , VL k )+TP(R VTm , VL k );

[0079] And according to the total number of people load TP (VL k ) to obtain the total number of personnel loads TP inside the tunnel. The specific formula is: TP = TP (VL1) + TP (VL2) ... + TP (VL1 -1)TP(VL1);

[0080] And according to the total number of personnel load TP inside the tunnel and the proportion of different types of personnel R PTj Get the total number of personnel loads TP of the corresponding type of personnel j ,TP j =TP×R PTj In a specific embodiment, the system outputs the calculation result in this step, such as Figure 4 As shown, it provides a basis for the setting of personnel load and distribution parameters in the numerical model of highway tunnel evacuation.

[0081] Further, step S50 is executed to randomly arrange the vehicles in each lane to obtain a corresponding arrangement set VArray (VL k ), VArray(VL k ) contains: VN k (VT1) VT1, VN k (VT2) VT2, VN k (VT3) VT3…VN k (VT m-1 ) VT m-1 , VN k (VT m ) VT m The difference between the permutation sets obtained by random arrangement is that the order of arrangement is different, and the length of each set is equal to the number of vehicles VN in the corresponding lane. k .

[0082] Further, step S60 is executed to calculate the vehicle arrangement set VArray (VL k ) and the average vehicle distance VS in each lane k The positions of all vehicles in each lane are obtained and output in FDS code until the FDS codes of all vehicles in all lanes are output.

[0083] Specifically, X start As a starting point, VS k For spacing, follow VArray(VL k ) to arrange the vehicles. The X end coordinate of the ath vehicle in the arrangement is set to X a,end , and assume that the type of the a+1th vehicle in the array is VT i , then the starting X, Y, and Z coordinates of the a+1th vehicle are a+1,start ,X a+1,end , Y a+1,start ,Y a+1,end ,; Z a+1,start ,Z a+1,end , and can be calculated using the following formulas.

[0084] X a+1，start =X a，end +VS k ;

[0085]

[0086]

[0087]

[0088] Z a+1，start = Z 0;

[0089]

[0090] Furthermore, the system outputs the FDS code of the a+1th vehicle in the kth lane, such as “&OBST XB=X a+1,start ,X a+1,end , Y a+1,start ,Y a+1,end ,; Z a+1,start ,Z a+1,end / ". Preferably, if other modeling parameters (such as COLOR, SURF_ID, MATL_ID, etc.) are set in step S10, the output FDS code also includes the above parameters. Steps S50 to S60 are repeated cyclically until the FDS codes of all vehicles in all lanes are output.

[0091] Furthermore, step S70 is executed to substitute all the output FDS codes into the target fire simulation or evacuation simulation software to establish a highway tunnel fire simulation or evacuation simulation model including vehicles.

[0092] Specifically, the FDS code generated in step S60 is imported into the fire simulation software Pyrosim, which can be used to quickly establish a highway tunnel fire simulation model containing vehicles; or the FDS code generated in step S60 is imported into the evacuation simulation software Pathfinder, and the personnel load parameters are set according to the results calculated in step S60, which can be used to quickly establish a highway tunnel evacuation simulation model containing vehicles; other necessary FDS codes can also be added based on the results calculated in step S60 and the generated FDS code, and other necessary parameters can be set, and then the FDS software can be directly used for fire simulation or evacuation simulation. In this embodiment, the fire simulation model and the evacuation simulation model are established by this step, and the distribution differences of different types of vehicles in different lanes are taken into account, so that the model is closer to the actual situation, and the simulation results obtained are more scientific and accurate.

[0093] In addition, considering that the distribution positions of different types of vehicles have an impact on the spread and transportation of fire smoke and the evacuation of personnel, the system can randomly generate multiple groups of FDS codes that meet the above parameter requirements under the same tunnel numerical model space coordinates, vehicle size, vehicle model ratio, lane distribution differences of different vehicle models and other parameters. Then, referring to step S70, multiple groups of fire simulation models or personnel evacuation models are established based on the above FDS codes for simulation, and the simulation results of each group of models are mathematically statistically processed (such as finding the average value, median value, probability distribution, standard deviation, variance, etc.), thereby providing more sufficient data support for evaluating the safety of tunnel fires.

[0094] Furthermore, in order to improve the accuracy of the simulation structure of the created model, relevant settings for personnel types and corresponding vehicle models can be further set. For example, elderly women, elderly men and minors cannot be matched with small trucks or large trucks, and minors cannot ride in a certain model alone, etc. Special conditions can be set for some special personnel types, thereby enriching the conditions for model creation, which is conducive to simulating and generating vehicle deployment methods corresponding to different actual situations.
