盐渍土由于具有特殊的物理化学性质,在自然条件下缺乏稳定性。因而使盐渍土地区修筑的道路经常发生盐胀、翻浆、淋溶湿陷等病害,使3公路路面出现网裂、变形、波浪和鼓包等破坏,严重影响交通运输和公路养护的正常进行,从而,导致了巨大的和间接经济损失。因此,改造和提高盐渍土地 Saline soil due to its special physicochemical properties, lack of stability in natural conditions. As a result, diseases such as salt expansion, leaching, leaching and collapsing often occur in the roads built in the saline soil so that the demarcation, deformation, waves and drum kits of the 3-lane road surface seriously affect the normal operation of transportation and road maintenance, As a result, huge and indirect economic losses result. Therefore, rebuilding and raising salty land
