摘要
我国西北地区湿陷性黄土分布广泛,而其作为一种特殊性土,在外部荷载及降雨的影响下,很容易发生强度破坏。鉴于此,以兰州地区某黄土基坑滑塌边坡为例,采用刷坡+实心钢管桩+土钉的治理措施,并通过数值模拟方法验证了该加固措施的合理性。其结果可以为同类地区相似工程边坡的治理提供有效的参考经验。
The collapsible loess is widely distributed in the northwest regions of China. As a kind of special soil, it is prone to strength failure under the influence of external load and rainfall. In view of this, taking a sliding slope of loess foundation pit in Lanzhou as an example, this paper introduces the application of the treatment measures of brushing slope + solid steel pipe pile + soil nail, and verifies the rationality of this reinforcement measures through the numerical simulation method. The results can provide the effective reference experience for the treatment of the similar engineering slopes in the similar areas.
