本文主要研究场区风化裂隙水对高填方稳定性的影响,通过几个红层地区的机场高填方实践研究,总结得出泥岩顶面溢出的风化裂隙水是西南红层地区高填方稳定性分析与评价的重要组成部分。研究思路是风化裂隙水渗入填筑体中,湿化、软化砂岩填料,通过分析填料的性质变化来研究填方边坡的稳定性。本次主要利用WDX-06剖面进行计算分析,根据现场调查研究得出:机场高填方地基工程地质条件差,多以崩洪积碎石土为主,在其下方往往分布有厚层状泥岩,地下水沿泥岩顶面溢出,渗入到填筑体内部,对填料进行湿化、软化,影响填方体的稳定性。
In this paper, we mainly study the effect of site fissure water on the stability of high fill. Through the practice of airport high fill in several red beds, we conclude that the weathering fissure water overflowing from the top of mudstone is the high fill of southwest red beds Stability analysis and evaluation of the important components. The research idea is to study the stability of filling slope by analyzing the infiltration of weathering fissure water into the infill body, wetting and softening the sandstone packing, and analyzing the change of packing properties. The main use of WDX-06 section of the calculation and analysis, based on the field survey found that: high-filled airport foundation engineering geological conditions are poor, mostly in the collapse of gravel, mainly in the distribution below the thick layer of mudstone , The groundwater overflows along the top of the mudstone, penetrates into the interior of the infilling body, humidifies and softens the packing, and affects the stability of the filling body.
