近几年来随着交通事业的发展,二级公路的建设已比较普遍,并出现一级乃至高速公路的建设。由于一、二级公路路幅宽、路面厚、路基压实度高,也就产生了路基土方工程量计算方面的新问题。主要有:(1)填方地段土方工程数量计算能否沿用三、四级公路土方的计算办法。(2)填方工程中购买土方的费用在预算中列入哪项计算比较正确。(3)路基压实度高产生的土方差怎样计算和压路机台班差怎样调整。
In recent years, with the development of transportation, the construction of secondary roads has become more common and the construction of first-class and even highways has emerged. As the first and second class road width, thick pavement, subgrade compaction, also resulting in subgrade earthwork calculation of new problems. The main ones are: (1) Whether the calculation of the earthworks at the filling site can follow the calculation method of earthworks on the third and fourth class roads. (2) It is more correct to include the cost of purchasing earthwork in the project in the budget. (3) How to calculate the earthwork deviation caused by the subgrade compaction and how to adjust the shift of the roller machine.
