The invention relates to a treatment and prevention method of saline soil on an airport runway, in particular to the technical field of airport runway construction. According to the technical scheme,the treatment and prevention method comprises the steps that the removal depth of saline soil is selected according to engineering geological conditions firstly, and original ground is rolled and leveled after the saline soil is removed; a waterproof curing layer is laid on the original ground and a composite geomembrane is laid on the waterproof curing layer; sand gravel cushion is laid on the composite geomembraneto fill and compact in layers; the top edge of the sand gravel cushion is covered by the composite geomembrane. The treatment and prevention method of saline soil on the airport runway has the effects of stable structure and long-term stable prevention function, and is used for the treatment and prevention of saline soil on the airport runway. 本发明涉及种机场场道盐渍土处理和防治方法，具体涉及机场场道建设技术领域。采用的技术方案是：先结合工程地质条件选取清除盐渍
