ABSTRACT:The present invention belongs to the field of construction safety state detection technology, to a surface buildings and underground structures effect relationship measurement method, measurement platform based on ArcGIS software, including graphics zoom, pan; graphics and attribute data query each other and work together on the same screen display ; analysis and other evaluation results are shown in the form of graphs, charts and documents; blasting vibration safety evaluation; surface modification of static and dynamic calculations; floor building pressure ring calculate weight; damage evaluation of ground structures; damage evaluation of underground structures; raster and vector data raster data vectorization, used simulation software interface expansion; its reliable measurement principle, measurement process simple steps, measured with high precision measurement of advanced technology and equipment, good stability, can be widely used in a variety of ground security building and underground structures effect relationship between the measured and warning.

The object of the present invention to overcome the shortcomings of the prior art, to seek determination of the interaction between the design of a surface buildings and underground structures to achieve underground construction on the ground near the security implications of existing buildings and ground works Construction on the proximity of existing underground structure determination and the security implications of scientific evaluation, based on the use of the relevant specifications for drug safety evaluation, combining theoretical research, field testing, laboratory tests and numerical simulation, evaluation content and evaluation system programming using fractal theory, coordination theory and intelligent search algorithm theory and algorithms were measured and evaluated, measured and evaluated results to achieve scientific and comprehensive.

To achieve the above objects, the present invention is measured based on ArcGIS software platform, including graphics zoom, pan; graphics and attribute data query each other and work together in the same interface displays; analysis and other evaluation results are shown in the form of graphs, charts and documents ; blasting vibration safety evaluation; static surface deformation (final form) and dynamic (deformation) computing; ground construction weight calculation pressure ring; damage evaluation of ground structures; damage evaluation of underground structures; rasterized vector data and raster data vectorization , commonly used numerical simulation software interface expansion; its measurement process, including database construction, underground construction structure of the building on the ground floor building role of evaluation and the evaluation of the construction of underground structures in three steps:

(1) Database Build: Build the database includes basic database and the database analysis and evaluation of two parts, the basic database including graphical and attribute database, wherein the graphic database for storing topographic maps, plans, geological maps, drilling Figure ground building maps, maps of underground structures; property database includes ground building (structure) information (such as civil, industrial, embankments, etc.), underground structural information (such as underground railways, underground storage, underground business, etc.) and geological information (such as formation, topography, geological structure, hydrogeology, environmental geology and seismic geology, etc.); analysis and evaluation database including the evaluation criteria and evaluation results database database, wherein the database includes blasting vibration evaluation criteria and evaluation standards, the relevant standards of surface deformation and evaluation, ground construction (structures) damage evaluation criteria and evaluation, drug safety assessment of underground structure evaluation criteria and evaluation; evaluation results database for storing the results of analysis and evaluation, through expanding space seamless integration of graphics and attribute database formation database, to facilitate the process of providing for further evaluation of intermediate results, or provide a basis for future reference, according to the corresponding national norms finishing stored in the database, but according to the project site experience, means theory, numerical experiments and similar material to obtain the relevant tests research results in the database evaluation criteria and evaluation indicators enrich and improve;

(2) the role of underground construction structure building ground evaluation, including blasting vibration safety assessment, surface deformation is expected, pressure ring floor building weight calculation and evaluation of surface damage buildings; blasting vibration safety assessment of the known distance measuring point burst Centrosymmetric the maximum dose calculation, comprehensive evaluation of internal forces, displacement response and the amount of ground-level structures of the largest known drug safety distance calculation blasting vibration, blasting vibration intensity, ground structure by blasting vibration impacts and by establishing a model to calculate Evaluation of the results stored in the database; the surface deformation of surface deformation is expected to be static (final form) and dynamic (deformation) expected by improved PECK formulas and stochastic medium theory formula for the surface deformation static (final form) prediction; using self-developed fractal interpolation method of calculating the value of the surface deformation dynamic deformation process, and the corresponding graphs and calculations to evaluate the results of database storage; damage evaluation of buildings were on the ground structure and masonry structure of the concrete structure of the building site survey Results evaluate the damage by establishing numerical model, using self-developed building damage prediction model for underground construction structure of the building on the ground due to injury a comprehensive evaluation, and the evaluation results are stored in the evaluation of the database;

(3) Ground building construction of underground structures for the evaluation, including the determination of the calculation surface buildings and underground excavation deformation caused by structural stress, displacement, the underground structures lining the forces of rock and soil after release stress and crack; measured to calculate the ground construction excavation blasting vibration effects on underground structures; the impact caused by underground pressure ring configuration of the measurement calculated load weight of buildings, through the establishment of analytical models to evaluate the measurement results stored in the database, complete ground construction Determination of the relationship between the role of the underground structure.
