| 摘 要： | 研究了水位变化对山区沿河半填半挖路基稳定性的影响,水位变化速度越快,路基整体安全系数越小,路基填料渗透系数越大,路基整体安全系数越大。因此,设计沿河路基边坡支挡防护工程时,应考虑河道水位实际变化规律对路基整体稳定的影响;半填半挖路基填料宜采用渗透系数较大的填料。

| Abstract: | The impact of water-level fluctuation on part-cut and part-fill subgrade stability in mountain area along the river is studied.The faster water-level fluctuation rate is,the smaller the overall safety factor of subgrade is;the bigger the osmotic coefficient of subgrade fillings is,the bigger the overall safety factor of subgrade is.Therefore,when designing the slope retaining protection engineering of subgrade along the river,the impact of actual change rules of riverway water-level on the overall stability of subgrade shall be considered.Part-cut and part-fill subgrade fillings shall adopt fillings with bigger osmotic coefficient. |
