淤泥的爆坑与表面条形药包装药处理软基的实验研究

提出用泥面爆炸填石排淤方法代替常用的泥下爆炸填石排淤。用模型实验研究了药量、水深和药包埋深之间的相互关系，给出了泥面爆炸的药量公式，揭示了覆盖水深和药包埋深与爆坑形状的关系。在此基础上可以进行爆炸处理软基的优化设计。

EXPERIMENTAL STUDY ON TREATMENT OF SOFT FOUNDATION OF BLASTING SLUDGE PIT BY LINEAR CHARGE SURFACE BLASTING

In this paper,a new method,in which squeezing the sludge by a blasting on sludge surface replaces the general method of blasting inside the sludge is introduced.A series model experiments on the relationship among the quantity of the charge,the depth of cover water and the depth of the charge under the surface of the sludge are carried out.The results of the model experiments give a charge formula of the surface blasting and the relationship between the shape of blasting pit and the depth of cover water and the depth of the charge under the surface of the sludge.Based on the results,design of the treating soft foundation by blasting can be optimized.
