In the case of the example 3, the following examples are given,
if the east minor ocean mouth complete equipment project is positioned at the tail part of the rotten sand ocean water channel of the radial sand ridge group, a wharf and an equipment processing factory area are built by utilizing a land area formed by the circumference of a tidal flat, and cargo can be conveniently fed in and out by taking a tidal ditch at the tail part of the rotten sand ocean as a navigation channel.
(1) According to relevant engineering data of a complete set of base of the small ocean mouth reconfiguration equipment, an engineering seawall construction BIM model is established, main structures such as a dike core sand quilt, bagged sand filling and slope protection are generalized in the process of building the model, a parameter form is formed through secondary development, and modeling of the BIM model in the construction period of the engineering seawall is completed.
(2) The basic method of BIM modeling in the construction period of the sea wall engineering (water conservancy and harbor navigation engineering) is summarized, two concepts of a composite structure and a composite structure parameter form are provided, the modeling difficulty of the sea wall BIM model is reduced, the operation, interaction and engineering application capability of the model are improved, a foundation is laid for the deep utilization of the BIM in the subject field,
(3) in the sea wall modeling process, the sea wall BIM model is deeply partitioned according to the arrangement of the engineering deformation monitoring section, so that the development of a subsequent dynamic monitoring system is facilitated. Similar subareas are designed comprehensively by combining construction flowing water sections and deformation monitoring sections in future research, so that the application range and the practical capability of model engineering are expanded.
The BIM modeling of the sea wall engineering is complex, on one hand, BIM software represented by Revit is adopted, the structural family library of the BIM software is mainly beams, plates and columns which are commonly used in buildings, and similar to common sand quilts, geotextiles, slope protection surface layers, fence plates, wave walls and the like in the sea wall engineering, no corresponding model family library is matched with the BIM software; on the other hand, many structures such as geotextiles and soft body mats are in two-dimensional forms and are difficult to be represented in three-dimensional BIM. And as for prefabricated special-shaped components such as fence boards and the like, the modeling difficulty of a single component is high, and the number of the components is large, one component is visually presented in a model, so that the challenge is brought to the software and hardware system of the whole computer. The BIM modeling of the sea wall is realized by the complete set of base engineering sea wall BIM of the eastern minor ocean mouth reconfiguration equipment, the BIM modeling difficulty of the sea wall is reduced, and the modeling task of the whole sea wall is completed.
In the BIM model, besides the geometric form of the component, the parameters of the component such as material, mechanical property and the like can be inquired through a family library. The sand quilt structure contains two kinds of materials, the hydraulic fill sand and the woven geotextile bag used for wrapping the hydraulic fill sand. The material performance of the woven geotextile bag is particularly important for field construction and later operation and maintenance, but after a model component is drawn by using a 'volume technology', corresponding parameter setting cannot be designed by using a model family library. Therefore, through secondary development, a parameter form for describing the complex structure of the sand quilt is developed, and key parameters such as the spatial position, the geometric form, the physical performance and the like of the sand quilt are set uniformly.
Slope protection structure and fill between the husky quilt, have certain space, the sand bag that generally adopts the small volume in the engineering piles up the packing, ensures that slope protection structure atress transmission is even. The structure is called bagged sand caulking for short. The family of bagged sand caulking libraries is also not available in the Revit software. If each bagged sandfill seam is modeled separately, it is time consuming to pile up one in the model space, and has no meaning. Therefore, aiming at the gap between the slope protection structure and the sand filling quilt, the gap is generalized into a whole rather than small sand bags which are dispersed one by one through a massiveness technology in Revit software, and then the solid model is formed. As long as the corresponding engineering quantity can be estimated accurately, the generalized model can completely guide the site construction, thereby reducing the difficulty and time of modeling and the requirements on computer software and hardware.
After the bagged sand joint filling is integrated, a parameter table needs to be developed. In the modeling process, the space positions and basic geometric forms of bagged sand filling of seawalls of different bank sections are slightly different, adjustment is carried out by means of mouse operation, and the adjusted related parameters are displayed through a parameter table. Although each small sandbag is generalized in the modeling process, the small sandbags also have the tensile resistance and the water seepage resistance, and the corresponding parameters are also specified in the parameter table. In addition, because the size of each sandbag in the bagged sand filling is basically consistent, the volume of each sandbag is determined in the parameter table, and the sandbag filling method is helpful for controlling the using amount of the sandbags. Through the technical means, the bagged sand filling joint component can be repeatedly stored, quoted and modified in the model, and corresponding parameters can be adjusted and set through a parameter table to serve for further application of subsequent engineering.
(4) Different projects have different requirements for deformation monitoring. Due to the particularity of the construction of the soft-foundation coastal seawall, the elevation, the displacement and the settlement of the preset seawall section must be monitored every day according to the requirements of the seawall construction specifications. And the regular elevation orderly monitoring is consistent with the advancing rhythm of the construction progress, thereby providing convenient conditions for the subsequent BIM rehearsal site. This is an advantage not available in other professional civil engineering.
Monitored data needs to be stored time by door by a specially developed database so as to ensure that the BIM can be read accurately in real time. If the mobile terminal is configured during field manual monitoring, the data of the field monitoring is input into the mobile terminal and is wirelessly transmitted to the platform, the field observation and the model updating are synchronously carried out, and the efficiency is higher.
As described in this embodiment, due to the particularity of the seawall engineering, deformation monitoring is performed once a day during construction, and the corresponding section elevation, settlement and displacement monitoring data can be applied to the stability of the analysis engineering and also provide a reference for comprehensive management of seawall construction. Specifically, according to the modeled sea wall construction BIM model, elevation can be automatically updated by the model after being converted into model component elevation through a certain algorithm according to daily monitored section elevation, and meanwhile, corresponding construction stages are judged through the algorithm, so that not only can on-site quality management be assisted, but also on-site construction stability can be analyzed and next-stage construction tasks can be simulated by combining finite element analysis while the on-site actual progress is visualized.
According to the embodiment, the dynamic monitoring system for seawall construction based on BIM, the application method and the system provided by the invention at least realize the following beneficial effects:
the method can monitor the elevation, settlement and displacement of the sea wall section in the construction period, determine the monitoring content of deformation according to the time-varying characteristics of the sea wall in the construction period, and formulate a corresponding BIM modeling scheme. Particularly, the seawall heterosexual structure is modeled in a generalized mode, a composite structure BIM model and a corresponding parameter form are provided to replace a traditional BIM family library, modeling is completed, efficiency is high, accuracy is high, the main process of site construction can be accurately reflected, and early warning is carried out in real time. Finite element analysis is carried out on the time-varying sea wall construction to obtain corresponding safety assessment, and the method can assist relevant management of on-site engineering quality, safety and progress and is favorable for comprehensive management of projects. The above results can be further applied to the operation and maintenance management of the seawall.

It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the invention.
