盐渍土地区路基病害的防治措施

Prevention and Disposal Measures to Diseases of Highway Subgrade in Saline Soil Area

通过对盐渍土进行机理方面的深入研究,得出盐渍土路基中水分、盐分随温度的变化规律,通过在路基内不同深度设置不同类型的隔断,观测到水分、盐分随时间的迁移和聚集情况。这一研究结果有助于有效治理盐渍土地区的公路病害,延缓道路的早期破坏,延长盐渍土地区公路的使用寿命。

Through the in-depth research on the mechanism of saline soil, the changing rule of moisture and saline matter in saline soil subgrade with the change of temperature is founded. By setting different type of partition at different depths of subgrade, the transference and conglomeration of moisture and saline matter with time passing is observed. The study result helps to dispose the diseases of highway in saline soil area, delay its premature failure, and prolong its service life.
