Application Of Highway Reconstruction And Extension Technology In Ganzi Trunk Highway

In the road reconstruction and expansion project,the uneven settlement of the roadbed is inevitable,and the uneven settlement of the old and new roadbed is the root cause of the disease caused by the road reconstruction and expansion project.Therefore,reducing uneven settlement is the key to the roadbed widening technology of highway reconstruction and expansion projects.Based on the successful technology of highway reconstruction and expansion project,the method of determining the expansion and expansion plan by using the analytic hierarchy process and the fuzzy level comprehensive evaluation method is studied.According to the similarity and particularity of the mountain reconstruction and reconstruction road project,the following research work is completed in combination with the engineering example.According to the characteristics of mountain road engineering and the uneven settlement of post-construction roadbed,the basic characteristics of the uneven settlement of new and old roadbeds in mountainous roads are analyzed.The research is different in different width and width,different filling heights and new and old roadbeds.The settlement characteristics of uneven roadbed and the law of uneven settlement under the condition of stiffness modulus ratio are considered.At the same time,considering the characteristics of mountainous landforms,the difference between uneven settlement of roadbed under different engineering conditions in different mountainous sections and slope sections is discussed.Based on the damage theory of the combination of new and old roadbeds,the causes and common diseases of uneven settlement of new and old roadbeds in the reconstruction and expansion project of mountain roads are discussed.Combined with the reconstruction and expansion project of mountain roads in Wajiu Road,the reconstruction plan of mountain roads is discussed.Choice and construction process control,with one Engineering practice.
