Abstract
A trial on the embankment construction by using fully lateral blasting for silt-squeezing was carried out firstly in the sea reclamation project of Lianyungang airport industrial park in China,a permanent section of revetment only required the dumping of stones and lateral blasting,which led to high efficiency.In the case,an introduction to the above method was made,including the main technical concepts,the design of blasting parameters,trial construction process,construction quality inspection and evaluation.Based on the detected section,Swedish slice method and finite element method were used to analyze and evaluate the stability and displacement of the section of the completed embankment.The conventional end blasting method was compared with fully lateral blasting for silt squeezing into order to analyze their characteristics.The results showed that fully lateral blasting for silt squeezing was of a higher efficiency and reduced the quantities of filling materials in the construction of embankment and revetment with a sludge treatment depth of less than 15 m and a bottom width of less than 30 m from the center of the embankment.In addition,and the method could also meet the requirements for the stability of the embankment.关键词
