芯吸土工织物-泥岩混合土路基排水效果模拟研究OA

The drainage effect of wicked geotextile-mudstone mixed soil subgrade was quantitatively studied by nu-merical 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 con-struction of foundation engineering in mudstone areas.
