三峡库区重庆一巫山段崩塌滑坡的危险性评价

EVALUATION OF COLLAPSE AND LANDSLIDE RISK IN THE THREE GORGES RESERVOIR(FROM CHONGQING TO WIJSHAN)

摘要: 对三峡库区近千个崩滑体的数据运用SPSS统计软件及EXCEL统计表格进行处理、分析,得出一些有益的结论;在稳态(稳定程度)基础上,计算得出崩塌、滑坡的危险性指标,并运用每10 km以内崩塌、滑坡的平均危害面积,对库区(重庆主城区一巫山段)的崩塌、滑坡进行危险性评价;同时,也计算出重庆市各区县长江干流的崩塌、滑坡的危险性指标。

Abstract: To deal with the data of CAL files, SPSS and EXCEL software were used here. Some valuable conclusions and some risk index of collapses and landslides were obtained on the bases of the stability. The risk division was made,using the average disastrous area of collapses and landslides every 10 km along the Yangtz River ( from Chongqing to Wushan),at the same time this thesis calculated the risk index of collapses and landslides along the river.
