摘要

摘要: 对滑带土加固改良有助于改善滑带土的工程性质，提高滑坡体抗滑稳定性能。以某移民迁建场地项目场区边坡为原型，根据相似理论构建边坡物理模型，利用人工降雨模拟装置对离子固化剂灌浆加固前后的边坡物理模型进行人工降雨试验，研究坡体示踪点应力和位移分布规律，分析降雨条件下坡体破坏模式及演化过程。试验结果表明：土压力及孔隙水压力受离子固化剂对边坡滑带层的加固效应影响明显；在滑带土灌浆加固后，边坡模型变形破坏的临界降雨总量与降雨强度明显增大，滑坡发生时累计降雨量约为加固前的9.14倍；边坡由整体性的滑动垮塌破坏变成局部性的蠕滑破坏，边坡滑移过程持续时间增长，蠕滑破坏后模型形态基本保持完整；在破坏持续时间内，离子固化剂可灌性良好，用离子固化剂灌浆加固后的边坡更为稳定，即离子固化剂加固改良滑带土可以有效地改善边坡的抗滑稳定性。

Abstract: Strengthening and improving the sliding zone soil is helpful to improve the engineering properties of the sliding zone soil and the anti-sliding stability of the landslide. Taking the slope of a resettlement site project as the prototype， the physical model of the slope was constructed according to the similarity theory， and the physical model of the slope before and after grouting with ionic soil stabilizer was reinforced by artificial rainfall simulation device. The stress and displacement distribution of the tracing point of the slope were studied， and the failure mode and evolution process of the slope in rainfall conditions were analyzed. The test results showed that the soil pressure and pore water pressure were obviously influenced by ionic soil stabilizer on the reinforcement effect of slope sliding zone. After the sliding zone soil was grouted and strengthened， the critical rainfall amount and rainfall intensity leading to the deformation and failure of the slope model obviously increased， and the cumulative rainfall when the landslide occurred was about 9.14 times that before the reinforcement； the whole sliding collapse of the slope changed into local creep failure， and the duration of the slope sliding process increased， and the model shape basically remained intact after the creep failure. During the duration of destruction， the ionic soil stabilizer had good injectability， and the slope strengthened by grouting with ionic soil stabilizer was more stable. The improvement of sliding zone soil by ionic soil stabilizer could effectively improve the anti-sliding stability of the slope.
