| 摘 要： | 大塘子滑坡属于我国西南地区典型的第四纪崩坡积松散堆积体滑坡.从滑坡的发育特征调查和资料收集入手,研究了该滑坡的形成条件和演化机制,分析认为降雨和地震联合作用诱发滑坡的产生,且滑坡具有明显的周期性,其形成过程经历"碎石体堆积-自然休止状态-显著滑动"3个演化阶段,存在再次滑动的可能性,其周期长短主要受降雨强度和地震活动的影响.这一结果对于合理部署区域防灾减灾具有指导意义.

| Abstract: | Datangzi landslide is a typical Quaternary period loose congeries landslide in Southwest China.The detailed studies of the forming condition and evolvement mechanism of Datangzi landslide were carried out based on in-situ surveys and data collection.It is shown that the combination of prolonged rainfall and the Lijiang earthquake should be the main cause of the landslide;and the landslide may revive in some day.One development process includes three main phases such as avalanche accumulation,nature inactivi... |
