Calculation value is cumulative to realize energy consumption and the accumulation calculating of pollutant emission and output in construction process of asphalt pavement, and asphalt road is built with this
Face is mated formation Discrete Event Models.Specifically, by the bituminous paving paving hazard abstract shown in Fig. 2, with reference to each of the determination of table 2
Process parameter and each elementary event key elements of EZStrobe, you can the Discrete Event Models of asphalt pavement construction are built, such as Fig. 3 institutes
Show.Since event charging Load, transport Travel, discharging Dump, the Pave that paves, compacting Compact are according to condition carried out successively
And Return is returned, by taking object " Load " as an example, dumper is represented in mixing building charging event, " Triangular [2.5,
3.0,3.5] it is " dumper charging spent time, left side connection arrow connection " AsphToPave " is by mixing that mixing building is produced
Material quantity is closed, ">0,12 ", which represents each Load events, enters guild from mixing building compound 12 tons of asphalts of transport.The model
The definition of its dependent variable is similar with Load events.Paving process is divided into two groups of events, respectively Pave1 and Pave2, Pave1

Discharging next time (after the completion of Pave2 events, ManeuvSpc values Jia 1)；Pavelength is then used to control road roller pressing practical work part
Beginning condition, after making reaches certain distance, that is, carry out Compact1 first pressing, Compact2 press again, Compact3 final pressure,
Three Continuous compacting operations.
Step 3, discharge computation model and energy consumption calculation model are built
This step uses Output functions in EZStrobe to build NONROAD energy consumptions and pollutant emission computation model.
Step 3.1, each calculation formula is determined according to NONROAD databases, obtains each parameter value.In NONROAD energy consumption moulds
In type, mainly counted according to energy consumption parameter (BSFC, power, combined emission factors), time parameter and loading coefficient parameter
Calculate energy consumption and the discharge of construction procedure.
Each calculation formula is as follows in NONROAD databases：
For estimating the formula of paving equipment energy consumption：
EC=BSFCPFl·t
In above formula, ECThat is energy consumption, unit liter；BSFC is brake specific fuel consumption, is disappeared per hour per power equivalent under fully loaded
The fuel oil number of consumption, unit is L/hp*h；P is brake specific fuel consumption rated power；FlIt is loading coefficient, refers to actual power and specified work(
The ratio between rate；T is the paving equipment operating time.
Q=Re×P×Fl×t
Q is discharge, unit of gram in above formula；ReFor combined emission factors.CO, NOx and particulate pollutant PM10Row
Putting the factor can find in NONROAD databases.
CO2Combined emission factors calculation formula：
CO2=(BSFC453.6-HC) 0.8744/12
HC, CO, NO of distinct device are consulted in NONROAD databasesX、PM10Emission factor and BSFC values, calculate
The CO of each step2、HC、CO、NOX、PM10Combined emission factors, as a result such as table 3 below：
Table 3
Step 3.2, discharge computation model is built
After the completion of road pavement Discrete Event Models are built, you can built using Output functions in EZStrobe
NONROAD energy consumptions and discharge computation model.Determined by table 1 and table 2 time parameter, loading coefficient, power, comprehensive discharge because
Son can define occurrence or function by Input functions in Discrete Event Models EZStrobe, therefore need to only calculate every event row
Put value and add up.Each pollutant emission function defined in Output functions, its numerical computations is with reference to the pollutant in step 3.1
Discharge Q formula, after the completion of simulation, EZStrobe can export pollutant emission total value, and each construction procedure discharge.
With CO2Exemplified by discharge is calculated, according to representative charging (LoadEmission), transport (TravelEmission), return
Return (ReturnEmission), discharging (DumpEmission), pave (PaveEmission), be compacted (CompactEmis), etc.
The CO in (the TruckIdleEmis, PaverIdleEmis) stage of time2Emission amount calculation function is simulated successively, each construction procedure
In use pollutant emission Q formula in step 3.1, Parameters in Formula takes the respective value of current construction procedure.After the completion of,
EZStrobe can export CO2Discharge total value, and each construction procedure CO2Discharge.CO2Total emission volumn (ToTCO2) calculate function
Such as according to formula：
ToTCO2=LoadEmission+TravelEmission+ReturnEmission+DumpEmission
+Pave1Emission+Pave2Emission+Compact1Emis+Compact2Emis+
Compact3Emis+Compact3Emis+TruckIdleEmis+PaverIdleEmis
The total emission result of each pollutant using the discharge computation model simulation of foundation is as shown in Figure 4.It can be seen that, construction equipment
CO in greenhouse gas emission2Proportion highest, the CO that the 1000 tons of asphalts that pave are produced2At 4 tons or so；Pollutant is arranged
Put predominantly NOX, its discharge capacity in 12kg or so, next to that CO, HC and particulate pollutant, respectively 2.1kg, 1.8kg,
0.2kg。
Analog result statistics is carried out to the pollutant that each construction procedure is produced, as shown in figure 5, pollutant emission is main next
Transport is in source and paves, and the two accounts for more than the 50% of total amount, and the pollutant that truck Light Condition, loading, discharging are produced is minimum.
In addition, returning, compacting and paving machine waiting process also generate certain pollutant.
The pollutant emission ratio that each work progress is produced is different, paves, the pollutant that compacting process is produced is mainly
NOX, account for 50% of total release or so.Transportation primary discharge CO2, its total emission volumn also accounts for total CO2The 50% of discharge capacity is left
It is right.The two originates for main discharge.
Pollutant emissions different to each apparatus, which are made, to be counted as shown in fig. 6, dumper is the main next of discharge with paving machine
Source, the former is CO2Discharge be up to 2.5 tons, the latter NOXDischarge capacity be 7.5kg, the 60% and 70% of total amount is accounted for respectively.Steel wheel pressure
The discharge capacity of road machine is larger compared to rubber-tyred roller.
Step 3.3, energy consumption calculation model is built
Using the computational methods of NONROAD energy consumption formula, the event for being related to energy resource consumption in each construction procedure is defined, with reference to
Analogue data and variable in EZStrobe, definition calculate similar Output functions with pollutant emission.By table 1 and table 2
Identified BSFC, time parameter, loading coefficient, power, combined emission factors can be in Discrete Event Models EZStrobe
Input functions define occurrence or function, therefore need to only calculate the energy consumption of each construction stage and add up.Defined in Output functions
The energy consumption function of each construction stage, including charging (Load), transport (Travel), return to (Return), discharging and (Dump, pave
(Pave), compacting (Compact), waiting (TIdle, PIdle) stage, its numerical computations is with reference to the energy consumption E in step 3.1C's
Formula, after the completion of simulation, EZStrobe can export the simulation of energy consumption result in asphalt pavement construction each stage.
Each construction procedure energy consumption result such as Fig. 7 simulated using the energy consumption calculation model of foundation.As a result show, often pave
1000 tons of asphalts, the diesel consumption that each paving equipment is produced is about 1500L, and being mainly derived from for energy resource consumption was transported
Journey, the diesel oil that the process is consumed is 663L, accounts for the 44% of total amount.In addition, the energy of paving process and dumper return course
Source is consumed also than larger, and the 32% and 12% of total amount is accounted for respectively.
Step 4, arrangement and method for construction improves Comparative result
Start with terms of construction technology and equipment two and arrangement and method for construction is improved.
From aforementioned analog analysis result, transportation and the main energy consumption source that paving process is work progress, and
It is higher that both account for gross contamination thing discharge ratio.Therefore, corresponding special construction process optimization can be taken to reduce discharge.
Original construction technology is changed to the new technology that uninterruptedly paves：When compound will pave completion, the haul of waiting
Car can be slowly interfaced close to paver, and then paver promotes dumper to advance.Because paver is in continuous work all the time
Make state, the discharge of paving machine Light Condition can be greatly reduced.Using this construction technology, in terms of transport, self-unloading card can be avoided
Collision, the extruding of vertical direction of the car in discharging to paver horizontal direction, reduce compound and unload impact caused by material bin,
It can also avoid, because improper operation makes compound unrestrained etc., making the more preferable smooth operations of paver；, can be to stand at the aspect that paves
Paving machine is continuously and smoothly fed to be paved with ensureing that paver is continuously continual.According to the uninterrupted work progress that paves, according to step
Discrete Event Models after rapid 2 pairs of improvement are modeled, such as Fig. 8.
Repeat step 3 obtains energy consumption and discharge computation model, and energy consumption discharge is carried out to the arrangement and method for construction after improvement and is calculated, is obtained
Contrasted to analog result with basic model energy consumption discharge result of calculation.From Fig. 9 (a), the continuous type mode that paves only exists
Paving process and dumper and paving machine waiting process slightly reduce energy consumption.From the construction work after Fig. 9 (b), improvement
Skill is to reducing NOXThere is obvious effect, every 1000 tons of compounds can reduce 2kg discharges, while greenhouse can be reduced slightly
Gas CO2Discharge capacity.
With CO2And NOXExemplified by, as seen from Figure 10, pollutant is arranged when the continuous type mode of paving significantly reduces waiting state
Put, the discharge of paving process also has a certain degree of reduction.In addition, the raising for the efficiency that paves reduces the dumper waiting stage
Discharge, but it is less to the contribution of overall emission reduction.With CO2Discharge contrasts similar, NOXEmission reduction also occur mainly in paving machine wait
State, waiting process NOXDischarge be greatly reduced, the pollutant emission of paving process is greatly reduced.
In terms of construction equipment, dumper and the main source that paving machine is that work progress is discharged to dumper and are paved the way
Machine is adjusted, and Main way is the appropriate capacity for increasing laying equipment.New laying equipment parameter and each equipment NONROAD moulds
The calculating parameter such as table 4 below of type discharge：
Table 4
New energy consumption and discharge computation model, simulation of energy consumption comparing result after being improved are built with the parameter that improves equipment
As shown in figure 11.As shown in Figure 11 (a), increase dumper and paving machine place capacity significantly reduce transport, return and
The energy consumption of paving process, saves diesel consumption 50% or so.As shown in Figure 11 (b), the capacity of appropriate increase laying equipment can subtract
Few greenhouse gases CO2With HC discharge, the former CER is 25% or so, and the latter is 17% or so；However, CO, NOXAnd particle
Pollutant emission increased.
In summary, the present invention solves the problem of existing construction process of asphalt pavement effect on environment data are estimated.Tool
When body carries out scheme optimization, if being improved construction technology, need to build corresponding Discrete Event Models；If to construction equipment
It is improved, then needs that new NONROAD databases insertion is built to new energy consumption discharge computation model by the parameter that improves equipment.
As needed, construction technology and construction equipment can also be simultaneously improved, now needs to build new Discrete Event Models
Computation model is discharged with new energy consumption.
