摘　　要：新昌县玄武岩台地貌滑坡主要与地质特征和降雨强度、时长有关。通过资料收集整理、工程地质分析、数理统计分析和综合对比研究等方法,分别对玄武岩地区滑坡与地层岩性、工程地质条件以及降雨特征之间的关系进行分析,得出了适合于新昌县玄武岩台地滑坡的降雨阈值I-D曲线,并结合分段性降雨特征分析对其予以进一步修正。对于进一步准确揭示降雨条件下玄武岩台地区滑坡失稳阈值具有理论研究价值和现实指导意义。The basalt platform landslide in Xinchang County is mainly related to geological features,rainfall intensity and duration.By means of data collection,engineering geological analysis,mathematical statistical analysis and comprehensive comparative research,the relationship between landslide and stratigraphic lithology,engineering geological conditions and rainfall characteristics in the basalt area was analyzed,respectively.The I-D curves of rainfall threshold suitable for the basalt platform landslide in Xinchang County were obtained,and further modified based on combining the segmented rainfall characteristic analysis.It has theoretical research value and practical guiding significance for further accurately revealing the landslide instability threshold in basalt platform area under rainfall conditions.
