2.数据预处理：(1)对采集的数据进行去噪处理，确保数据准确性。(2)把历史采集的数据（包含本次采集）进行聚合，形成数据集X，并针对数据集X中的碎石化层施工平整度字段，计算出其平均值。
3.计算线性回归斜率a和截距b：基于数据集X（以碾压次数为自变量、碎石化层施工平整度为因变量），运用SLOPE函数，基于最小二乘法原理确定斜率a；运用INTERCEPT函数确定截距b。斜率a表示单位碾压次数变化对碎石化层施工平整度的影响程度，截距b表示基准碾压次数下碎石化层的施工平整度。
4.结果运用：（1）计算比例系数k：k=|a/碎石化层施工平整度平均值|×100%；（2）若k≥10%，则判定为“高影响”，若5%≤k＜10%，则判定为“中影响”，若k＜5%，则判定为“低影响”。

This dataset focuses on analyzing the impact of rolling pass count on the construction flatness of crushed stone layers, and reveals the quantitative relationship between rolling pass count and the construction flatness of such layers. Enterprises can use this dataset to study the influence law of different rolling pass counts on the construction flatness of crushed stone layers, accurately adjust the operating parameters of construction technology, and improve the quality of crushed stone construction. This dataset is applicable to relevant researchers, technical R&D personnel, project supervisors, and engineering quality inspectors in the crushed stone construction field, providing support for them to carry out related work such as predictive analysis, mechanism research, quality control, scientific research, and technical optimization of crushed stone engineering from the perspectives of rolling pass working conditions and construction flatness of crushed stone layers.
1. Data Collection: Record the test data of construction flatness of crushed stone layers under different rolling pass working conditions, including specific fields such as test point number, test time, rolling pass count (times), and construction flatness of crushed stone layers (unit: mm).
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 construction flatness field of crushed stone layers in dataset X.
3. Calculation of Linear Regression Slope a and Intercept b:
Based on dataset X (with rolling pass count as the independent variable and construction flatness of crushed stone layers as the dependent variable), use the SLOPE function to determine the slope a based on the principle of least squares; use the INTERCEPT function to determine the intercept b. The slope a represents the degree of influence of unit change in rolling pass count on the construction flatness of crushed stone layers, and the intercept b represents the construction flatness of crushed stone layers under the reference rolling pass count.
4. Result Application:
(1) Calculate the proportional coefficient k: k = |a / average value of construction flatness of crushed stone layers| × 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".
