堤防及穿堤建筑勘察与除险加固分析

Investigation and Risk Removal and Reinforcement Analysis of Embankment and Crossing Embankment Buildings

江河堤防作为抵御洪水的主要屏障,在防洪工程体系中发挥着重要作用。但在我国现有堤防工程中,普遍存在堤基地质条件差,堤身填筑质量差、堤后坑塘多等问题,高洪水时易发生管涌、塌岸和漫溢等险情。以庙潭围堤防为例,通过详细的地质勘察并从堤身现状、堤基地质结构、险情隐患部位等方面对工程进行病险分析,并对拟建穿堤建筑站址进行勘察,提出地基加固处理措施,为堤防的除险加固和穿堤建筑的建设施工提供了地质依据。

River embankment,as the main barrier against flood,plays an important role in the flood control engineering system.However,in the existing embankment projects in China,there are many problems,such as poor geological conditions of embankment base,poor quality of embankment filling and many pits behind embankment.During high flood,it is liable to occur dangerous situations such as piping,bank collapse and overflow.Taking Miaotanwei embankment as an example,through detailed geological investigation,this paper carries out risk analysis on the project from aspects of embankment body status,geological structure of embankment base,dangerous hidden parts,and carries out investigation on the proposed embankment crossing construction site,and puts forward foundation reinforcement treatment measures,which provide geological basis for embankment risk removal and reinforcement and construction of embankment crossing construction.
