黄土崩塌

提出了陕北宅基边坡伤亡性黄土崩塌的防治措施。

The prevention-cure measure for the landfall is put forward .

计算结果表明：①宅基边坡伤亡性黄土崩塌的稳定性随谷缘坡体坡度的增大而降低；

The results indicate that the stability of the landfall reduces with the increase of gradient of it .

模拟再现了陕北宅基边坡伤亡性黄土崩塌的形成机制，验证了治理此类崩塌的有效措施&建成的宅基边坡谷缘坡度不得大于天然谷缘坡度。

The mechanism and main prevention-cure measure of cutting the top of loess slope according to its nature gradient for the landfall are quantitatively reformed and simulated .

以5个典型宅基边坡伤亡性黄土崩塌为例，利用塑性极限分析和极限平衡法，推导出了此类黄土崩塌的稳定性与其坡度之间的关系。

Taking five representative casualty loess landfalls on the house side-slope as examples , applying the method of limit analysis of soil plasticity and the ultimate equity method , the equation of the stability and gradient of the landfall is derived .

通过宅基边坡伤亡性黄土崩塌变形破坏的地质力学模式分析，将此类崩塌分为斜坡谷缘拉裂谷缘坡体蠕动短滑带形成并贯通崩塌土体剪出4个阶段。

On the basis of the geomechanical model for slope deformation and destruction , the developmental process of this landfall is divided into four stages , which are valley-side margin ripping , margin slope creeping , the short slip belt being formed and pierced , and the landfall befallen .

地表沉陷是由灌溉水的充填引起黄土结构崩塌造成的。

The ground subsidence was due to collapse of loess soil caused by applying irrigation water .

Reasons for the frequent occurrence of the collapse calamity to the loess cave dwelings in the Yulin area and the Prevention-cure Countermeasures

讨论了陕北黄土高原既毁窑又伤人的伤亡性黄土崩塌的类型、前兆、时空分布特征，着重分析了这类崩塌形成原因。

In this paper the casualty loess landfall are classified into two types according to their modes of development : tension-sliding loess landfall and collapsed earth cave dwelling .
