Description
Technical Field
The application belongs to the technical field of building information models, and particularly relates to a system and a method for three-dimensional development and digitization of a rail transit station.
Background
The rail transit station refers to a vehicle section, a parking lot, a station, auxiliary facilities and the like of rail transit, and the three-dimensional development of the rail transit station refers to the simultaneous development of the rail transit station under the cover, namely the rail transit facilities under the cover, and the building development by utilizing the upper space of the rail transit station.
At present, as urban land utilization comprehensively enters a stock stage, three-dimensional development is carried out on an upper cover of an rail transit station to become an important means for realizing efficient intensive land utilization, and meanwhile, necessary supplementary funds can be provided for rail transit development through the three-dimensional development of the rail transit station, so that a main body unit of rail transit construction is fed back.
In recent years, with the promulgation of related policies and standards, a part of three-dimensional development projects of rail transit stations have entered an implementation stage, but there are more problems:
(1) The standardization and standard of the three-dimensional development project of the rail transit station are not perfect
Because the three-dimensional development project of the rail transit station is developed in recent years, related special specifications are less, and the current Shanghai market landmark, namely the urban rail transit upper cover building design standard, is published in 2018, and the industry standard, namely the urban rail transit upper cover structural design standard, is not published, so that the related specification standard is disconnected from the rapid expansion of the project to solicit opinion manuscripts in the whole.
(2) Project development and urban area fusion immaturity
In the conventional stereoscopic development project of rail transit stations, the situation that the station cover development and surrounding urban areas are fused together is often caused, for example: the difference between the track crossing overall line network construction progress and the city design or updating scheme time, insufficient knowledge of planning designers to surrounding areas, and the like.
(3) The structural design method is imperfect
Because of the specificity of the three-dimensional development project of the rail transit station, the structural design and calculation, the earthquake-resistant design and the related analysis and design method of calculation are not perfect, and some detail nodes have no unified standard atlas and design method. Such as: the design principle and design method of the conversion layer are not perfect, and as the vehicle section or subway station structure is covered under the conversion layer, most of the conversion layer is a frame structure, most of the conversion layer is covered on the conversion layer, and the conversion layer is used for carrying out structural conversion between the bottom frame and the upper structure, but the problem of abrupt change of rigidity exists, and damage concentration is easy to occur under the disastrous effects of earthquake and the like.
In addition, if the under-deck rail traffic portion is subjected to attack, continuous collapse from the underframe to the plurality of high-rise buildings on the deck may be induced, and the content of the portion needs to be fully studied.
(4) Fire and emergency management
The three-dimensional development project of the rail transit station belongs to the project of the civil and civil building co-construction, and no specific fireproof standard exists at present, so that the aspects of personnel evacuation, fire rescue, fire-fighting facilities, fireproof separation, structural fireproof performance and the like all need to be fully demonstrated and can be implemented.
(5) Construction problems
The stereoscopic development project of the rail transit station is required to preferentially meet the requirements related to rail transit, but due to the difference and the specificity of the on-cover and off-cover development, the on-cover development is generally delayed, and the condition that the on-cover and off-cover rail transit operation occurs and the on-cover is still under construction is caused. At this time, the construction requirement on covering the building is higher, on the one hand, the construction needs to be guaranteed not to influence the normal operation of the lower rail crossing of the cover, on the other hand, the tower crane and other construction facilities cannot fall to the ground, and need to fall to the slab concrete platform, and the usable place is smaller, and the tower crane foundation and the overlength adhesion construction have higher technical difficulty.
In addition, due to the specificity of the rail intersection three-dimensional development project, the adopted structural technology is complex, such as box-type conversion, shock absorption and isolation, an assembled structure and the like, and the construction requirement is high.
(6) Collaborative management problem
Because the three-dimensional development project of the rail transit station often relates to a plurality of construction, design and construction units, the characteristics of the three-dimensional development of the project need multi-party cooperation, and the traditional management mode has certain limitation.
On the design level, the traditional working mode is to exchange scheme files among units and professions in a resource-raising mode, on one hand, each participating party is mutually restricted, the traditional resource-raising mode is disordered and irregular, and the construction progress of the whole project can be influenced to a certain extent; on the other hand, the scheme file exchange is carried out among the professions in a funding mode, and the scheme inconsistency among different professions finally can be caused by forgetting or omission of the funding party.
On one hand, in the construction layer, the traditional design drawing intersection mode can cause the problems of reworking, low construction progress and the like, and resource waste because the constructor understands wrong, and the actual construction situation is inconsistent with the drawing; on the other hand, the rail transit three-dimensional development project can involve a plurality of construction units, and a corresponding responsible person when a problem is difficult to timely and clearly appear in a conventional construction management mode can appear.
