摘要
为探究影响锚杆腐蚀行为的主要因素以及锚杆腐蚀对锚固边坡稳定性的影响,对锚杆开展了不同腐蚀条件下的腐蚀性试验和受腐蚀锚杆拉伸试验,获得了不同腐蚀条件下锚杆的力学性能演化规律。研究发现,锚杆的力学性能与Cl-质量分数和腐蚀时间呈负相关。当锚杆处于干湿循环环境下,力学性能的影响主要与Cl-质量分数有关。在相同条件下,腐蚀时间对于锚杆力学性能的影响更为显著。此外,借助Geostudio软件开展了锚杆腐蚀对边坡稳定性的影响研究。结果表明,随着Cl-质量分数和腐蚀时间的增加,边坡稳定系数降低。
To investigate the key factors affecting the corrosion behaviour of anchor rods and the impact of anchor corrosion on the stability of anchored slopes,corrosion tests under different corrosion conditions and tensile tests of corroded anchors were carried out.Subsequently,the evolution laws of the mechanical properties of anchors under different corrosion conditions were acquired.It is found that the mechanical properties of anchor rods are inversely correlated with Cl-concentration and corrosion time.When the anchor rods are dry⁃wet cycle environment,the mechanical properties are affected by Cl-concentration.Under the same conditions,the effect of corrosion time on the mechanical properties of anchors is more significant.The impact of anchor corrosion on the stability of slopes was simulated using GeoStudio software.The results show that the slope stability coefficient decreases with the increase of Cl-concentration and corrosion time.
