摘　　要：以龙岩市永定区现代特色农产品科技产业基地(一期)启动区道路工程为研究对象,通过现场调查、工程地质分析与岩土测试等手段,查明了场地孕灾地质背景条件,分析了岩土工程效应,提出了区域岩土体设计参数建议取值,并对场地的适宜性以及可能造成的工程风险进行了评价,最终提出了工程措施建议。结果表明,场地位于花岗岩地区,无构造断裂通过,花岗岩残积土为区内不良性土。在施工过程中应避免因开挖和堆载等人类工程活动造成的危害,研究成果可为类似工程提供经验参考。Taking the road project in the start-up area of the Longyan City Yongding District Modern Characteristic Agricultural Product Science and Industry Base(Phase I)as the research object.Through on-site investigation,engineering geological analysis,and geotechnical testing,the geological background conditions of the disaster-prone site was identified,the geotechnical engineering effects were analyzed,and suggestions for the design parameters of the regional geotechnical mass were proposed.The suitability of the site and the potential engineering risks were evaluated,and engineering measures were suggested.The results show that the site is located in a granite area without any tectonic fractures passing through.The granite residual soil is a poor soil within the area.It is necessary to avoid hazards caused by human engineering activities such as excavation and loading during construction,and the research results can provide experience reference for similar projects.
