Specific embodiment
Below with reference to test example and specific embodiment, the present invention is described in further detail.But this should not be understood
It is all that this is belonged to based on the technology that the content of present invention is realized for the scope of the above subject matter of the present invention is limited to the following embodiments
The range of invention.
Before carrying out Tunnel modeling, the line midline in tunnel 1 need to be established in 3 d modeling software first
2, as shown in Figure 1, the reference by location that the line midline 2 is modeled as preliminary bracing.When the line alignment for needing to change tunnel 1
When, it is only necessary to the line midline 2 is modified, and preliminary bracing model can automatically update therewith.
The component of Tunnel includes system anchor bolt, lock foot anchoring stock, advanced tubule, Shed-pipe Advanced Support, steelframe, reinforcing bar
Mesh sheet, longitudinally connected muscle, the present embodiment are described entire modeling process by taking anchor pole 3 as an example, the modeling of other each components
Thinking is similar with the anchor pole 3, only slightly has difference in the selection of relevant parameter.
A kind of Tunnel fast modeling method, comprising the following steps:
Step 1: in 3 d modeling software, the relevant parameter of anchor pole 3 in Tunnel, the related ginseng are set
Number includes form parameter and positional parameter.The form parameter include rock-bolt length, anchor pole outer diameter, anchor pole wall thickness, plate thickness,
Backing plate is long, backing plate is wide etc., and the positional parameter includes circumferential spacing, odd loop radical, even loop radical, longitudinal pitch, first ring
Mileage etc., as shown in Figure 2.
Step 2: the model of single anchor rod 3 is established in 3 d modeling software CATIA.It is carried out according to design drawing single
The foundation of 3 model of anchor pole, each parameter must be associated with the relevant parameter in step 1 when establishing, and the input feature vector of foundation must be
3 place outer contour of anchor pole and line midline must consider the mileage number for having an advance along route mileage direction in modeling approach,
The distance that outer contour has a circumferential direction to move along place is used for later period batch processing.Since the design of this single anchor rod 3 is rear
Phase is used as template, therefore under the premise of meeting above-mentioned requirements, where position be not required to be strictly required, but in battle array
When column, controlled by knowledge engineering language.
Step 3: 3 model of single anchor rod established in the step 2 is defined as user characteristics, for knowledge engineering language
Control uses.Notably following when user characteristics make: (1) all processes that single anchor rod 3 models and step need to be included
The whole parameters being arranged in one；(2) when making, dimension information corresponding with relevant parameter set in step 1 is complete
Portion issues out；(3) name of user characteristics, input condition name and the name of all kinds of relevant parameters must not all use Chinese,
As shown in Figure 3.
Step 4: based on user characteristics defined in the step 3, writing knowledge engineering language, makes it possible to modify
The modeling process of relevant parameter and the step 2 that reruns, logical process are relevant parameter of every modification, operation one
The modeling process of the secondary step 2, then relevant parameter is modified, rerun a modeling process, so repeats.It can directly utilize
Knowledge engineering array editing machine in CATIA is edited, as shown in Figure 4.By writing knowledge engineering language, so that " first
The anchor pole 3 for starting the first ring of arrangement at ring mileage " mileage points, is sequentially arranged " odd loop radical " quantity according to " circumferential spacing "
Anchor pole 3 after, along mileage advance " longitudinal pitch " length, start according to " circumferential spacing " and " even loop radical " arrange second
The anchor pole 3 of ring, recycles by this method, until completing the arrangement of Tunnel.
Total number of rings is arranged in order to control anchor pole 3, and " arrangement number of rings " can be set in the positional parameter in step 1,
So that being arranged into specified number of rings is just automatically stopped operation.In language compiling procedure, by circumferential spacing, odd loop radical, even loop
Radical, longitudinal pitch, rock-bolt length, anchor pole outer diameter, anchor pole wall thickness, plate thickness, backing plate is long, backing plate is wide, first ring mileage etc. is complete
Portion's parameter is contacted with knowledge engineering language foundation, is enable the smooth call parameters of knowledge engineering language, is achieved the purpose that Controlling model.
Step 5: it checks write knowledge engineering language, runs the knowledge engineering language, the anchor pole after inspection is errorless
3 along the circumferential of tunnel and longitudinal automatic arrangement, to complete the rapid modeling of Tunnel, as shown in Figure 5.
Step 6: it when encountering geologic change, when needing design alteration, can be carried out by way of changing relevant parameter.Wherein
There are two types of situations when adjustment: when (1) being related to the adjustment variation of anchor pole form parameter, directly modifying parameter and more new model can be complete
At, such as: rock-bolt length, outer diameter, wall thickness, plate thickness, backing plate length and width；(2) it when being related to arrangement adjustment variation, is modifying
After positional parameter, the knowledge engineering array finished writing is clicked by right key, click " update and upgrade ", software will recalculate automatically, so
It completes to update afterwards.As shown in Fig. 6 to Fig. 7.
Above embodiments are only to illustrate the present invention and not limit the technical scheme described by the invention, although this explanation
The present invention has been described in detail referring to above-mentioned each embodiment for book, but the present invention is not limited to above-mentioned specific implementation
Mode, therefore any couple of present invention modifies or equivalent replacement；And the technical side of all spirit and scope for not departing from invention
Case and its improvement, are intended to be within the scope of the claims of the invention.
