阳春市双滘镇大榜村背靠丘陵山坡,山体由寒武系的混合岩组成,表层风化岩土厚度较大,山势陡峭且发育有冲沟坳谷,岩土稳定性较差。本文通过充分分析评价区地质环境条件,通过采用定量计算及定性分析方法进行泥石流参数计算和危险性分析评价,为下一步对泥石流治理设计提供地质科学依据。 The village of Shuangliu Town in Yangchun City is backed by hilly slopes, and the mountains are composed of Cambrian mixed rocks. The surface weathering rock and soil thickness are larger, the mountainous steep and developed gully Au valley, rock and soil stability is poor. In this paper, by fully analyzing the geological conditions in the evaluation area, using quantitative analysis and qualitative analysis method to calculate the debris flow parameters and risk analysis and evaluation, it provides the geological scientific basis for the debris flow control design in the next step.
