摘要

［目的］在不同的降雨条件下，对黄土浅层滑坡进行危险性分析，为评价黄土地区浅层滑坡提供有效手段。［方法］以甘肃省天水市为例，根据SHALSTAB模型，在ArcGIS中进行二次开发，编写不同降雨量时浅层滑坡危险性分析程序，计算不同降雨量下浅层黄土滑坡分布预测。［结果］随着降雨量的增加，浅层滑坡数量明显增多，所占面积比例从5 mm/d的0.166%增加为320 mm/d的3.624%，上升了20倍左右。［结论］当降雨量较小时，浅层滑坡分布于雨水集中汇积的区域，随着降雨的增加，浅层滑坡沿着黄土沟谷向上游延伸。通过和实际发生滑坡灾害进行对比分析，证明计算结果准确可信。

Abstract

[Objective] To analyze the risk analysis of loess shallow landslide under different rainfall conditions in order to provide an effective way for the loess shallow landslide hazard analysis and evaluation.[Methods] The paper took Tianshui City of Gansu Province as a case study and wrote a program to analyze the shallow landslide hazard according to SHALSTAB model under ArcGIS platform. Then the distribution of shallow loess landslide was predicted with consideration of different rainfall conditions.[Results] With the increase of rainfall

the shallow landslides increased significantly

and the proportion increased from 0.166% to 3.624% when the rainfall increased from 5 mm/d to 320 mm/d

increased by 20 times.[Conclusion] When the precipitation is low

shallow landslides area main distributed in rainfall concentrated area. When the precipitation increases

shallow landslides extend upward along the loess valley. The comparison with the actual landslide disasters showed that the calculation results are accurate and reliable.
