研究目的:通过观察黄土的一些自然特征,探讨水对黄土的作用方式,分析黄土边坡坡度与水之间的作用关系,以便工程边坡设计时充分考虑水对边坡稳定的作用,安全合理地确定边坡坡率和防护措施。研究结论:黄土的结构强度和抗剪强度对水极其敏感,抗剪强度中粘聚力随含水量的增加而迅速降低;边坡稳定取决于能否形成坡面浸润带,浸润带的强度随含水量的增加而迅速减小;高角度针状孔隙的存在是黄土直立性的本质所在;稳定的自然黄土边坡和窑洞边坡是物竞天择的科学选择,值得我们借鉴。
Research purposes: By observing some natural features of loess, discussing the effect of water on loess, analyzing the relationship between loess slope and water, so that the effect of water on slope stability can be fully considered when designing slope, which is safe and reasonable Determine slope slope and protective measures. Research conclusions: The structural strength and shear strength of loess are extremely sensitive to water, and the cohesion in shear strength decreases rapidly with the increase of water content. The stability of slope depends on the ability of forming slope infiltration zone. The strength of infiltration zone The water content increases and decreases rapidly. The existence of high-angle acicular pores is the essence of loess erection. Stable natural loess slopes and cave slopes are the scientific choice of natural selection, which is worth learning from.
