1 我国江河堤防的特点及隐患探测技术现状 我国现有的江河堤防特点有:一是堤基条件差。堤防傍河而建,堤线选择受到河势条件制约,堤防基础大多为沙基,而且绝大部分堤防未作基础处理,特别是有的堤防建在古河道或历史上决口后堵复的老口门上,堤基松软,容易出大险。二是堤身填土质量差。不少堤防是在原民堤的基础上,经历年逐渐加高培厚而成,往往质量不佳。有的因局
1 Characteristics of our country’s embankments and the status quo of hidden danger detection technology Existing embankments in our country are: First, the embankment conditions are poor. Embankments built near the river, the embankment line subject to the constraints of the river conditions, most of the foundation dike Shaji, and most of the embankments are not basic treatment, in particular, some embankments built in the ancient river or the historical burst after the old portruptcy The door, dykes soft, easy out of danger insurance. Second, the embankment filling quality is poor. Many embankments are built on the basis of the original embankment and are gradually becoming more and more developed through years of experience. They are often of poor quality. Some reason
