It provides key design optimization basis for the company (as a construction entity) and external relevant parties, holding significant engineering practical value, which is reflected in the following aspects: 1. Optimizing pile length design parameters: Construction entities can accurately determine pile length control standards by analyzing the influence law of different pile lengths on the bearing capacity of anchored static pressure piles, optimize construction efficiency while ensuring structural safety, thereby improving the economy of pile foundations and reducing the risk of excessive settlement. 2. Promoting the development of intelligent design technologies: This dataset provides basic support for geotechnical engineering research institutions and numerical analysis R&D units, helping them explore the correlation mechanism between pile length parameters and soil stress distribution, promoting the application of intelligent pile length optimization systems based on geological parameters in static pressure pile engineering, achieving collaborative optimization of bearing capacity requirements and project cost control, and leading pile foundation engineering towards digital design. 1. Data collection: Record the bearing capacity test data of anchored static pressure piles under different pile lengths, including specific fields such as test point number, test time, pile length/m, and bearing capacity of anchored static pressure piles/kN. 2. Data preprocessing: (1) Denoise the collected data to ensure data accuracy. (2) Aggregate the historically collected data (including this collection) to form dataset X, and calculate the average value of the bearing capacity field of anchored static pressure piles in dataset X. 3. Calculation of linear regression slope a and intercept b: Based on dataset X (with pile length as the independent variable and the bearing capacity of anchored static pressure piles as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares, and use the INTERCEPT function to determine the intercept b. The slope a represents the influence degree of unit pile length change on the bearing capacity of anchored static pressure piles, and the intercept b represents the bearing capacity of anchored static pressure piles under the reference pile length. 4. Result application: (1) Calculate the proportional coefficient k: k = |a / average bearing capacity of anchored static pressure piles| × 100%; (2) If k ≥ 10%, it is judged as "high impact"; if 5% ≤ k < 10%, it is judged as "medium impact"; if k < 5%, it is judged as "low impact".
