不稳定边坡地质灾害危险性评估技术探讨

Discussion on Dangerous Assessment of Geological Hazard on Unstable Slope

地质灾害危险性评估因建设项目评估级别不同,评估深度和精度也不同。一级评估应有充足的基础资料,在定性分析的基础上,采用定量、半定量的评价方法,进行充分论证。本文以某规划建设场地地质灾害危险性评估为例,探讨了一级评估中的不稳定边坡灾害种类的地质灾害危险性现状评估、预测评估和综合评估的定量评价方法,在类似不稳定边坡地质灾害危险性评估中具有参考和借鉴价值。

The depth and accuracy of assessment is quite different as assessment scale for in dangerous assessment of geological hazard constructive site is different. For the first rank assessment scale, enough basic information is essential and the assessment based on quatitative analysis should be fully proved by means of semi-quantitative to quantitative method. In this paper the quantitative methods for present, predictive and synthetic evaluations on unstable slope dangerous assessment of geological hazard are applied to a practice construction site. These methods can be used for reference on unstable slope dangerous assessment of geological hazard in similar practice.
