摘　　要：本文分析了广西桂林市雁山新城区防洪工程(二期)堤防工程的岩土体结构、物理力学性质、工程地质条件和水文地质条件。采用钻探、地质测量、室内试验等方法,研究了该工程的地质环境。结果表明,堤基地质条件为C类,具有多层结构;堤岸地质条件基本稳定,局部地段需采取植物防护措施;穿堤涵管、下堤踏步、上堤道路工程地质条件与相应位置防洪堤相一致。此外,确定了土料、砂砾料和石料等建筑材料的来源及质量标准。研究成果可为类似地层中岩土工程勘察提供参考。This study analyzed the geotechnical structure,physical-mechanical properties,engineering geological conditions,and hydrogeological conditions of the flood control project(Phase II)embankment in Yanshan New District,Guilin City,Guangxi Province.By drilling,geological survey,laboratory tests,and other methods,the geological environment of the project was systematically studied.The research results showed that the embankment foundation geological conditions belongs to Class C,with a multi-layer structure;The embankment geological conditions are basically stable,and vegetation protection measures need to be adopted in some local sections;The engineering geological conditions of the culvert through the embankment,the steps under the embankment,and the road on the embankment are consistent with the corresponding location of the floodwall.In addition,The paper determined the sources and quality standards of soil materials,sand and gravel materials,and stone materials.The research results can provide reference for geotechnical engineering surveys in similar strata in the future.
