基于最小二乘法的低等级公路改扩建设计研究

随着我国经济的飞速发展,道路交通量及交通荷载得到快速增长,早期修建的公路出现交通拥挤,路面大面积破损的情况,许多等级公路渐渐进入改扩建阶段。其中低等级公路由于道路初期建设标准较低,道路病害严重,其改扩建设计更为复杂。现基于最小二乘法原理,对老路进行平面拟合设计和误差分析,为低等级公路水泥路面的改扩建工程提供参考和借鉴。

Study on Design of Low-grade Highway Reconstruction and Extension Based on Least Square Method

With the rapid development of economy in China,the traffic volume and traffic load of road have rapidly increased.The highways built in the early days are congested.The pavements are damaged in the large scale.Many grades of highways are gradually entering the stage of reconstruction and extension.Due to the lower standard of construction at an initial stage,the low-grade highways are seriously damaged.The extension design of these highways is more complex.Now based on the principle of the least square method,the plane fitting design and error design are carried out for the old roads.The reference can be provided for the reconstruction and extension of cement pavements of the low-grade highways.
