地质灾害的发生除了地层岩性、地质构造、地形地貌等内在因素外,降雨量是常见和重要的诱发因素。不同的地质环境条件,诱发地质灾害的降雨量是不同的。本文根据不同的地质环境条件,将诸暨市地质环境分为脆弱区、较脆弱区、基本稳定区和稳定区4个区域,并分别建立了临界降雨量特征曲线,为预报预警提供科学依据。
The occurrence of geological disasters In addition to the formation of lithology, geological structure, topography and other internal factors, the rainfall is a common and important predisposing factors. Different geological conditions, the rainfall caused by geological disasters is different. According to different geological conditions, this paper divides the geological environment of Zhuji City into 4 regions: fragile zone, weaker zone, basic stable zone and stable zone, and sets up the critical rainfall characteristic curve separately, which provides scientific basis for forecasting and warning.
