Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a foundation measurement system and method for building construction, and more particularly to a foundation measurement and evaluation technology based on multi-source measurement data fusion, continuous spatial modeling of the foundation, and analysis of the mechanical characteristics of the foundation. Background Technology

[0002] During construction, foundation conditions directly affect structural safety and construction quality. Existing foundation surveying methods typically rely on single or limited measuring equipment to perform discrete point measurements of the construction area. The data obtained has limitations in terms of temporal consistency, spatial continuity, and measurement accuracy. Especially in complex geological conditions or large-scale construction scenarios, differences in sampling periods and coordinate references between different measuring equipment can easily lead to difficulties in uniformly processing the measurement data, thereby affecting the reliability of subsequent analysis results.

[0003] Furthermore, current technologies for processing foundation measurement data often remain at the level of surface elevation or local parameter analysis, lacking the ability to continuously model the overall three-dimensional structure of the foundation, and thus failing to effectively reflect changes in the underground structure and their spatial relationships. At the same time, there is a lack of effective assessment and suppression mechanisms for noise, outliers, and differences in reliability among different measurement points in the measurement data, resulting in insufficient accuracy in foundation bearing capacity analysis and settlement assessment results.

[0004] Furthermore, existing foundation surveying techniques have a weak correlation with construction design parameters, making it difficult to form an effective closed loop from surveying data to construction control parameters, and thus failing to provide a reliable basis for dynamic adjustments during construction. Therefore, there is an urgent need for a foundation surveying method and system that can integrate multi-source surveying data, construct a three-dimensional foundation structure model, and realize foundation mechanical characteristic analysis and construction evaluation to solve the above problems. Summary of the Invention

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a method for measuring the foundation of a building construction project, comprising the following steps:

[0006] Step S1: Simultaneous measurement of the construction area is carried out through multi-source foundation measurement unit to obtain original foundation measurement dataset. The original foundation measurement dataset includes spatial coordinate data, surface elevation data, underground response data and measurement timestamp. The original foundation measurement dataset is then time-aligned and spatially uniformly calibrated to obtain a standardized measurement dataset.

[0007] Step S2: Based on the standardized measurement dataset, construct a continuous spatial model of the foundation, perform spatial interpolation and error suppression processing on the discrete measurement points of the foundation, and simultaneously output the spatial reliability parameters of each measurement point to finally generate a three-dimensional foundation structure dataset.

[0008] Step S3: Based on the foundation three-dimensional structure dataset and spatial reliability parameters, model and analyze the foundation bearing characteristics, calculate the foundation comprehensive bearing parameters and uneven settlement characteristic parameters, and form a foundation mechanical characteristic dataset.

[0009] Step S4: Based on the foundation mechanical characteristic dataset and combined with the construction design reference parameters, generate foundation measurement and evaluation results, and output foundation correction parameters for construction control and correction.

[0010] Preferably, step S1 further includes:

[0011] Within the construction area, measurement points are arranged according to a pre-set measurement grid. A multi-source measurement array consisting of a total station, a laser scanning device, and a geological detection sensor is used to synchronously collect the foundation status of each measurement point, obtaining raw foundation measurement data including the spatial location information of the foundation surface, surface elevation information, underground medium response information, and corresponding measurement time information.

[0012] The multi-source measurement data collected from each measurement point are organized according to a unified data structure to form an original foundation measurement dataset containing data from multiple measurement points.

[0013] To address the differences in sampling times between different measuring devices, the time information in the original foundation measurement data is uniformly corrected based on the system's preset reference time, in order to eliminate time inconsistencies between multi-source measurement data.

[0014] After completing the time alignment process, based on the correspondence between the coordinate system of the measuring equipment and the engineering reference coordinate system, the spatial location information in the original foundation measurement data is uniformly transformed to eliminate the spatial reference differences between different measuring equipment and obtain a standardized foundation measurement dataset.

[0015] Preferably, step S2 further includes:

[0016] Based on the standardized foundation measurement dataset, a foundation spatial point set consisting of multiple discrete measurement points is constructed. The foundation spatial point set is used to characterize the spatial distribution characteristics of each measurement location within the construction area.

[0017] Based on the aforementioned set of spatial points of the foundation, a weighted spatial interpolation modeling method is used to perform spatial continuous modeling processing on discrete measurement points, generating a continuous foundation model to describe the changes in the spatial morphology of the foundation, thus transforming the foundation measurement results from discrete point form to a spatially continuous distribution form;

[0018] In the spatial interpolation modeling process, a spatial consistency constraint mechanism is introduced to suppress abnormal fluctuations in the interpolation results, so as to reduce the impact of measurement noise and local outliers on the overall modeling results.

[0019] Based on the deviation distribution between the interpolation modeling results and the actual measured data of the corresponding measurement points, the measurement reliability of each measurement point is evaluated, and the spatial reliability parameter corresponding to each measurement point is calculated.

[0020] Based on the spatial continuity modeling results and spatial credibility parameters, a three-dimensional foundation structure dataset containing spatial location, elevation information, and credibility information is generated.

[0021] Preferably, step S3 further includes:

[0022] Based on the aforementioned three-dimensional foundation structure dataset, the foundation within the construction area is divided into multiple spatial elements, which are used to describe the structural units of the foundation at different spatial locations.

[0023] For each volume element, a weighted analysis of its mechanical contribution in the bearing direction is performed based on its corresponding spatial reliability parameters to reflect the degree of influence of measurement results in different regions on the overall bearing capacity assessment.

[0024] Based on this, the bearing characteristics of each element are comprehensively analyzed, and the comprehensive bearing parameters characterizing the overall bearing capacity of the foundation are calculated.

[0025] Meanwhile, by comparing and analyzing the settlement differences of adjacent elements in the vertical direction, non-uniform settlement characteristic parameters reflecting the degree of uneven deformation of the foundation are extracted.

[0026] The final result is a dataset of foundation mechanical characteristics that includes the comprehensive bearing capacity and uneven settlement characteristics of the foundation.

[0027] Preferably, step S4 further includes:

[0028] The foundation mechanical characteristic dataset is compared and analyzed with the pre-set construction design benchmark parameters to assess the degree of deviation between the current foundation condition and the design requirements.

[0029] Based on the comparative analysis results, and taking into account the foundation bearing capacity and uneven settlement characteristics, foundation measurement and evaluation results are generated to characterize the overall applicability of the foundation conditions in the construction area.

[0030] Based on the foundation measurement and evaluation results, the foundation correction parameters used for construction adjustments are calculated in reverse.

[0031] The foundation correction parameters are output to the construction control stage to guide the adjustment and correction of subsequent foundation construction parameters.

[0032] This invention also discloses a foundation surveying system for building construction, comprising the following modules:

[0033] The multi-source foundation measurement and standardization module is used to perform multi-source synchronous measurement of the construction area, acquire raw foundation measurement data, and perform time alignment and spatial uniform calibration on the raw measurement data to generate a standardized measurement dataset.

[0034] The foundation 3D structure modeling module is used to construct a foundation spatial continuity model based on the standardized measurement dataset, perform spatial interpolation and error suppression processing on discrete measurement points, and generate a foundation 3D structure dataset containing spatial reliability parameters.

[0035] The foundation mechanics analysis and evaluation module is used to analyze the bearing characteristics and uneven settlement features of the foundation based on the three-dimensional foundation structure dataset, and generate foundation measurement and evaluation results and construction correction parameters in combination with construction design reference parameters.

[0036] The multi-source ground-based measurement and standardization module further includes:

[0037] The multi-source measurement data acquisition subunit is used to acquire ground surface spatial coordinate data, ground surface elevation data, underground response data and measurement time information through a multi-source measurement array consisting of a total station, a laser scanning device and a geological exploration sensor;

[0038] The time-space unified processing subunit is used to perform time alignment processing on raw measurement data from different measuring devices and to perform unified transformation of spatial coordinates based on the engineering reference coordinate system to form a standardized measurement dataset.

[0039] The foundation three-dimensional structure modeling module further includes:

[0040] The spatial continuity modeling subunit is used to construct a discrete spatial point set of the foundation based on a standardized measurement dataset, and to perform spatial interpolation processing on the discrete point set to form a spatial continuity structure model of the foundation.

[0044] The evaluation and construction correction output subunit is used to compare and evaluate the foundation mechanical feature dataset with the construction design reference parameters, generate foundation measurement evaluation results, and output foundation correction parameters to guide construction control and correction.

[0045] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0046] Improving the uniformity and reliability of foundation measurement data: This invention effectively eliminates the differences in sampling time and coordinate reference between different measurement devices by performing time alignment and spatial uniform calibration on foundation measurement data collected by multi-source measurement devices, thereby improving the consistency of multi-source measurement data in the time and spatial dimensions and providing a reliable data foundation for subsequent foundation modeling and analysis.

[0047] Enhancing the continuity and noise resistance of foundation spatial modeling: This invention performs spatial continuous modeling of discrete foundation measurement points and introduces spatial consistency constraints and measurement reliability evaluation mechanisms. This effectively suppresses local abnormal measurement values ​​and noise interference while maintaining the overall spatial morphological characteristics of the foundation, thereby improving the continuity and stability of the foundation three-dimensional structure modeling results.

[0048] Enhancing the guiding value of foundation assessment results for construction adjustments: Based on the three-dimensional structural modeling of the foundation, this invention further conducts a comprehensive analysis of the foundation bearing characteristics and uneven settlement features, and generates foundation measurement assessment results and construction correction parameters in combination with construction design benchmark parameters. This enables the foundation measurement results to directly serve the construction process control, improving the guidance and practicality of the foundation assessment results for adjusting actual construction parameters.
