【摘要】 江西省境内水系发达,堤防工程繁多,圩堤一般修筑在河湖岸坡上,堤基多为二元地质结构,在高水头压力作用下堤基薄弱部位极易形成渗漏通道;堤身填土多为黏土和粉质粘土甚至杂填土,经洪水长时间浸泡,易产生散浸、滑坡等;在暴雨和洪峰的影响下,洪水还可能漫堤而过,影响堤身的稳定.因此在汛期,应根据圩堤产生的各种险情,制定处理方案.本文结合2016年7月江西境内圩堤防汛期间出现的险情及处理方案对各类圩堤险情及处理方案进行详细的介绍,并针对江西省圩堤工程中存在的主要问题提出了一些建议,以期能为我省的防汛抢险工作提供一些参考.更多还原

【Abstract】 River network are well-developed and embankment engineering are numerous in Jiangxi province. The embankments are generally built on the bank slope of lakes or rivers,and almost all of the dike foundation are binary geological structure. Under high water head pressure, the weak part of dike foundation are easy to form leakage passage. The dike body are usually filled by clay,silt clay or miscellaneous fill. It is easy to form piping and landslide in the action of long soaking duration. Under the influence of rainstorm and flood,the flood may overflow the dike and influence dike stability. Therefore,we should produce various schemes to deal with all kinds of dangerous situation in flood season. The types of and the corresponding treatment scheme are described in detail by combining the dangerous situation and its treatment schemes of the embankments in Jiangxi province during flood season in July 2016. In addition,aiming at the main problems in embankment engineering,this paper put forward some suggestions,hoping to provide some reference for the flood control and rescuing in our province.更多还原
