当一个越岭方案选定后,选线人员的工作就是实地如何定线,目前我们采用一次定线的方法。根据近年来林区公路选线的实践,我们认为,只要采取慎重的态度,一次定线是可行的。定线前首先应对越岭方案所经过的各个控制点之间高差做到心中有数,以便确定二相邻 When a ridge plan is selected, the job of the line selection personnel is how to set the line in the field. At present, we adopt a method of alignment. According to the practice of selecting roads for forest roads in recent years, we believe that as long as a cautious attitude is adopted, one-time alignment is feasible. Before the alignment, firstly deal with the height difference between the various control points passed by the ridge plan to be sure to determine the two neighbors.
