摘要
对陕南膨胀土分布区土坎梯地普遍存在的严重垮坎现象进行调查分析表明,膨胀土吸水膨胀、强度锐减的土质特性是土坎梯地垮坎毁坏的根本原因。为解决陕南膨胀土分布区土坎梯地垮坎问题,应采取防水防风化的综合性措施。
Analysis and investigation of severe dam collapse often existing in soil ridge terraced land of dilatable soil areas in south Shaanxi demonstrate that the essential cause for dam collapse is acute decrease of strength of dilatable soil with moisture absorption and consequent expansion. The comprehensive treatment of prevention of moisture and wind should be adopted to solve the problem.
