防波堤基础的爆炸处理方法及应用

Blasting method of the breakwater groundwork and its application

为了快速有效地处理防波堤地基 ,采用了爆炸法处理地基的新方法 .包括堤端推进爆填、边坡拓宽爆填、加抛密实爆夯、边坡整理爆夯等方法 .通过玉环坎门防波堤工程中的应用、观察、比较 ,结果显示此方法费用省、工期短、沉移少、效益好 .能够比较彻底的置换淤泥层 ,夯实堆石体 。

In order to dispose the breakwater groundwork in a more rapid and efficient way, a new method of blast treatment is put to use. It includes blasting and filling of the end of the breakwater, blasting and filling of slope widening, blasting and tamping of consistence, blasting and tamping of slope renovation, etc. By observation and comparison of the method applied in the breakwater project at Kanmen, Yuhuan, the results reveal that this method can save the expense and time, reduce settlement and work efficiently. And it can replace silt more thoroughly, tamp enrockment and form the size and depth of every part according with the design.
