摘要：

The paper is concerned with design and construction of mountain roads in areas of high relief and steep mountain slopes, where the principal soil types are transported rather than residual and the landscape is shaped mainly by active erosion processes. In order to simplify the wide range of ground conditions encountered, the geology and geomorphology of typical mountain terrain are described and related to a five zone model. Geotechnical features within each zone are then considered so that the application of various investigation and construction techniques can be appreciated. The paper is primarily concerned with low-cost but well-trafficked primary roads where closure time due to slope failures or lack of maintenance are intended to be minimal. Refs.
