摘要;水对红层泥岩结构的破坏最为显著且不可逆,干湿循环作用会近一步加剧这种破坏,使红层泥岩发生变形,产生裂缝,导致红层泥岩内部结构损坏并不断累积,致使红层泥岩强度下降。因此,研究红层泥岩在干湿循环作用下的强度和变形特性的变化规律对分析边坡稳定、路基变形、地基稳定性等有积极作用。本文通过文献调研对红层泥岩在干湿循环条件下性质的变化进行了综合分析,总结了其在干湿循环条件下的强度衰减及变形发展规律,可为完善红层泥岩地区边坡设计、地基基础设计等提供参考.
Abstract: T'he damage of water to red mudstone structure is the most significant and irreversible, and the dry-wet cycle will furtheraggravate this damage. The red mudstone is deformed and cracks are producedl, which leads to the damage and accumulation of the intemalstructure of the red mudstone, resuling in the decrease of the strength of the red mudstone. Therefore,studying the strength and deformationcharacteristics of red mudstone under the action of dry-wet oycle has a positive effect on analyzing sope stability , sutbgrade deformation andfoundation stability. This paper comprehensively analyzres the propertis of red mudstone under dry-wet cycling through literature research,and summarizes the laws of strength attenuation and deformation development under dry -wet cycling conditions
which can provide
reference for improving slope design and foundation design in red mudstone area.
