1 沙河堤防特点及隐患探测情况沙河堤防高一般2.5～5.5m,最高处达8～9m,顶宽6～8m。它是在原民堤基础上,经过50年代治淮及“75·8”大洪水后的大规模人工培修而成。其特点一是堤防傍河而建,堤基大多为砂基,局部堤防修建在古河道上,堤基条件差,且大多未作处理,隐藏着较大险情。二是堤身修筑质量差。沙河堤防是经多次人工培修加固而成,局部夯实质量不均匀,新老堤结合面不
1 Shahe dike characteristics and detection of hidden dangers Shahe dike height is generally 2.5 ~ 5.5m, the highest point of 8 ~ 9m, the top width of 6 ~ 8m. It is based on the original dam, after 50 years of governance and “75.8 ” flood after a large-scale artificial training made. One of the characteristics of the embankment is built near the river, embankment mostly sand-based, built on the ancient dikes in the embankment, embankment conditions are poor, and most are not dealt with, hidden with greater danger. Second, the dike build poor quality. Shahe embankment is a result of artificial training and reinforcement made several times, the partial compaction of uneven quality, old and new embankment with the surface is not
