苏联流砂区从南到北延伸1,500公里,达到北纬48～52°,包括中亚各共和国,哈萨克斯坦和俄罗斯社会主义联邦共和国的下伏尔加。在这个不同气候条件的辽阔地区内,当流砂的外部相似时,公路的设计和建筑则有本质的差别。而哈萨克加盟共和国和俄罗斯社会主义联邦共和国的流砂区均属苏联的北方流砂分布区。
The USSR sand zone extends 1,500 km from south to north and reaches 48 to 52 degrees north latitude, including the Republics of Central Asia, Kazakhstan and the Lower Volga of the Russian Federation. In this vast area of different climatic conditions, there is an essential difference between the design and construction of a highway when the runoff is similar in its exterior. The fluvial sand areas of the Federated States of Accession to the Republic of Kazakhstan and the Socialist Federal Republic of Russia belong to the northern part of the Soviet Union where the sand is distributed.
