摘　　要：保定地区新近沉积土的物理力学性能及工程地质性能差,对其宏观识别与物理力学特性的研究,有助于更好地为工程建设服务。野外调查与工程实践表明:保定地区新近沉积土分为山区新近沉积土、平原区新近沉积土、洼淀区新近沉积土,由于地貌差异造成沉积环境不同,进而形成新近沉积土不同的宏观特征与物理力学性能;通过与邻近区域新近沉积土物理力学参数的比较、分析,认为该地区新近沉积土的工程地质性能与北京地区相近,好于石家庄地区;同时,针对该地区的新近沉积土,提出了相应的工程处理措施。The physical mechanical properties and engineering geological properties of the recently deposited soil is poor in Baoding area ,The study of the macroscopic identification and physical mechanical characteristics of the deposited soil is beneficial for the engineering constructions .Field investigation and engineering practice indicate that the recently de-posited soil is divided into mountain region sedimentary soil ,plain region sedimentary soil ,and low-lying region sedimen-tary soil in Baoding area . Because the topographical differences result in different sedimentary environment , different macro characteristics and physical properties of recently deposited soil is formed thereafter .Through the comparison and analysis of physical and mechnical parameters of the recently deposited soil in adjacent areas around Baoding ,it is con-sidered that engineering and geological property of recently deposited soil in Baoding area is close to that in Beijing area , but better than that in Shijiazhuang .According to its current situation in Baoding area ,corresponding engineering treat-ment measures were put forward .
