Abstract
The highway alteration project of the section from Meilin to Shanheling in Ninghai urban areas involves a line with a total length of 11.235 km. The section is designed according to the standard for the first-class highway with 4–6 lanes; the design speed is 80 km/h; and the subgrade width is 26.5–45 m. The transportation of earthwork is restricted during highway excavation in urban areas. In addition, the outsourced fillers are also prohibited due to the difficulty in transportation. Therefore, it is more appropriate to use the undisturbed soil to carry out the construction after the undisturbed soil is treated by lime. Specific judgment can be made from an economical and environmental protection perspective, as shown in Tables 12.1 and 12.2.
