| 摘 要： | 位于砂岩地层上的堆积层斜坡是重庆开县广大农村居民的主要生活生产场所,其位移变形直接关系着住户的生命财产安全.根据现场调查指出人口密度大、过度开垦是导致斜坡变形的重要人为因素.通过专业监测资料分析和实地调研,揭示出该类斜坡具有阶段性蠕滑、位移在雨季增长明显的变形特点,滑面通常位于土岩接触面或堆积层中黏粒含量较高且相对隔水的层面.这些结论可为地质灾害治理和西南地区城镇建设提供依据.

| Abstract: | The mass of countrymen are living on the deposit slopes at sandstone bedrock in Kaixian,Chongqing.The deformation of slopes affects severely the safety of lives and properties of the inhabitants.On the basis of field investigation,it is shown that the man-made reason of slope deformation is population explosion and excessive reclamation.According to the analysis of professional monitoring data and field investigation,it could be illuminated that the deformation of slopes is intermittently developing,and the... |
