含水量对边坡稳定性的影响分析

Analysis of the Influence of Water Content on Slope Stability

调查黄土地区的土壤含水量与边坡稳定性之间的关系.对土壤形式的样本数据进行测试,以获得塑性和液体边界,以便调查土壤强度及其与含水量的关系.通过确定初始条件下的样品强度参数进行试验,然后根据塑性和液体边界以及单位体积修改样品的含水量.试验结果表明,含水量是影响边坡稳定性的最重要因素.低于塑性极限的含水量也会导致重塑样品的土壤参数发生改变,导致土壤强度降低,边坡稳定性显著下降.为了减少边坡破坏,建议在该区域建立边坡含水量控制设施.

This paper investigates the relationship between soil moisture content and slope stability in loess areas.It tests sample data in soil form to obtain plastic and liquid boundaries,in order to investigate soil strength and its relationship with water content.This paper conducts experiments by determining the strength parameters of the sample under initial conditions,and then modifies the water content of the sample based on plasticity,liquid boundaries,and unit volume.The test results indicate that water content is the most important factor affecting slope stability.The moisture content below the plastic limit causes changes in the soil parameters of the reshaped sample,leading to a decrease in soil strength and a significant decrease in slope stability.In order to reduce slope damage,it is recommended to establish slope water content control facilities in this area.
