Simulation Study on Drainage Effect of Wicked Geotextile-Mudstone Mixed Soil Subgrade

通过数值模拟定量研究了芯吸土工织物-泥岩混合土路基的排水效果,提出了具有最佳排水效果时的芯吸土工织物基质吸力和边坡植被吸力。研究结果表明:芯吸土工织物可以有效降低泥岩混合土路基体积含水率;随着芯吸土工织物基质吸力和边坡植被吸力的增加,路基排水效果逐渐增强。相关结论有助于指导泥岩地区基础工程的建设。

The drainage effect of wicked geotextile-mudstone mixed soil subgrade was quantitatively studied by numerical simulation.The matrix suction of wicking geotextiles and suction of slope vegetation were proposed with the best drainage effect.The results show that wicked geotextiles can significantly reduce the volumetric moisture content of mudstone mixed soil subgrade;With the increase of wicked geotextile matrix suction and slope vegetation suction,the drainage effect of the subgrade is gradually enhanced.The relevant conclusions are helpful to guide the construction of foundation engineering in mudstone areas.
