边坡放样（包括填挖）一般是在已施测的断面上进行设计和放样，但在高速度进行施工的情况下，为了满足施工进展的需要，常须在一面施测断面，一面放样或在断面尚未施测即须根据设计进行放样。为此，有一些技术上的问题是值得加以研究的。 Slope lofting (including filling and excavation) is generally designed and laid out on the tested sections. However, in the case of high-speed construction, in order to meet the needs of the construction progress, it is often necessary to measure the section on one side and to stake out one side. When the section has not yet been tested, it must be laid out according to the design. For this reason, there are some technical issues that are worth studying.
