| Abstract: | The design and construction of mass volume high side slope cutting expansion of Hu-Hang-Yong highway,an existing one starting from Shanghai(Hu)through Hangzhou(Hang)to Ningbo(Yong),by deep hole water-pressure controlled blasting was introduced by focusing on the discussion of charging structure of borehole of deep hole water-pressure blasting,construction method of none-partition wall and none-lateral rack protection and achieved technological achievements plus their economic and social benefits.The present paper offered successful experience for similar engineering in the future. |
