摘要
2010年,强降雨导致江西省部分进行了除险加固的水库发生滑坡。为找出滑坡产生的原因,防止类似情况再次发生,以滨田水库大坝滑坡作为典型实例,重点分析了造成滑坡的影响因素,运用层次分析理论,推测了大坝滑坡的过程,从宏观和微观两个方面深入剖析其机理,认为在强降雨入渗条件下,新老土层结合部位产生静态液化是导致滑坡的主要原因,并在此基础上提出了相应的防治对策。
The landslides occurred in partial reservoirs in Jiangxi Province in 2010,which have experienced strengthening and danger removing projects.In order to find out the causes of landslide and prevent their recurrence,we analyzed the influential factors on the landslide by taking landslide of Bintian reservoir dam as a typical example.According to the theory and method of analytic hierarchy process(AHP),the landslide process is presumed;and the landslide formation mechanism is analyzed from the macroscopic and microscopic views.It is considered that under the condition of strong rainfall,the static liquefaction in the bonding area of new and old soil is the main cause of the landslide.Therefore,the corresponding countermeasures are put forward.
